Dermatologist-Approved Tips for Choosing a Safe and Effective Sunscreen

19. Reapply Regularly Consistent reapplication is crucial for maintaining sunscreen’s protective benefits throughout the day. Even the most effective sunscreen can lose potency due to sweat,… Alina Yasinskaya - August 22, 2025

Skin cancer is the most common cancer in the United States, with over 5 million cases diagnosed each year, according to the American Cancer Society. Despite growing awareness, only about 30% of Americans regularly use sunscreen, as revealed by a CDC report. As the body’s largest organ, the skin plays a vital protective role. However, under-protection and late detection remain serious challenges, underscoring the importance of effective sun protection habits for long-term skin health.

1. Check for Broad-Spectrum Protection

When selecting a sunscreen, it is essential to choose one labeled as “broad-spectrum.” This designation means the product protects against both UVA and UVB rays, which are the primary contributors to skin damage and skin cancer. UVA rays penetrate deeply, accelerating skin aging and increasing the risk of melanoma, while UVB rays cause sunburn and play a key role in developing skin cancers. According to the U.S. Food and Drug Administration (FDA), only sunscreens explicitly marked as “broad-spectrum” have demonstrated effective protection against both types of radiation.

When comparing sunscreen labels, look for the term “broad-spectrum” on the front of the packaging. Products that do not carry this label may only shield against UVB rays, leaving your skin vulnerable to the long-term effects of UVA exposure. The Skin Cancer Foundation recommends broad-spectrum sunscreens for comprehensive sun defense. To ensure optimal protection, always verify this wording before purchasing, and avoid products that list only a Sun Protection Factor (SPF) rating without mention of broad-spectrum coverage.

2. Opt for SPF 30 or Higher

Sun Protection Factor (SPF) measures how effectively a sunscreen protects the skin from UVB rays, the main cause of sunburn and a contributor to skin cancer. An SPF rating indicates how much longer it would take for skin to burn compared to unprotected exposure. For example, SPF 30 filters out about 97% of UVB rays, while SPF 50 blocks approximately 98%. Although the increase in protection above SPF 30 is marginal, dermatologists recommend using SPF 30 or higher for reliable coverage, especially during prolonged outdoor activities.

According to the American Academy of Dermatology (AAD), SPF 30 is the minimum level recommended for daily use. Lower SPFs, such as SPF 15, only block about 93% of UVB rays, leaving more room for cumulative damage. It’s important to remember that no sunscreen offers 100% protection, so a higher SPF complements, but does not replace, other sun-safe behaviors. When choosing a sunscreen, check the label for SPF 30 or greater to ensure adequate defense for all skin types, as supported by the Centers for Disease Control and Prevention (CDC).

3. Understand Physical vs. Chemical Sunscreens

Sunscreens are typically divided into two main categories: physical (mineral) and chemical. Physical sunscreens, which use active ingredients like zinc oxide or titanium dioxide, act as a shield on the skin’s surface, reflecting and scattering UV rays—much like a mirror bouncing sunlight away. Chemical sunscreens, on the other hand, contain ingredients such as oxybenzone, avobenzone, or octinoxate that absorb UV rays, converting them into harmless heat, similar to how a sponge soaks up water.

Physical sunscreens are often recommended for sensitive skin or young children because they are less likely to cause irritation and provide immediate protection upon application. Their visible white cast can be a drawback for some, though newer formulations have improved in this regard. Chemical sunscreens are generally lighter and more cosmetically elegant, making them ideal for daily wear or under makeup. However, some ingredients may cause sensitivity in certain individuals. According to the American Academy of Dermatology, both types offer effective protection when used correctly. Choose a physical sunscreen for water activities or sensitive skin, and opt for a chemical formula for lightweight, invisible coverage during everyday use.

4. Read the Active Ingredients

Understanding the active ingredients in sunscreen is crucial for both safety and efficacy. Common physical (mineral) filters include zinc oxide and titanium dioxide, both recognized by the U.S. Food and Drug Administration (FDA) as safe and effective. These minerals sit on top of the skin, physically blocking and scattering UV rays. Chemical filters, such as oxybenzone, avobenzone, octinoxate, and homosalate, absorb UV radiation and convert it into heat. Some, like oxybenzone, have raised concerns about skin sensitivity and environmental impact, though they remain widely used in the U.S.

To choose a safe product, review the active ingredients listed on the packaging. The Environmental Working Group (EWG) suggests opting for mineral-based formulas if you have sensitive skin or wish to avoid certain chemicals. Look for sunscreens labeled “zinc oxide” or “titanium dioxide” as the sole active ingredients for the gentlest option. Always check expiration dates, and avoid products with fragrances or parabens if you have allergies or sensitivities. Reading labels carefully ensures you’re making an informed, dermatologist-approved choice for your skin.

5. Avoid Oxybenzone and Octinoxate

Oxybenzone and octinoxate are common chemical sunscreen ingredients, but recent research has raised concerns about their safety for both humans and the environment. According to the FDA, additional studies are underway to assess the long-term health effects of these chemicals, as they can be absorbed into the bloodstream after topical application. Some individuals may experience allergic reactions or hormonal disruptions from oxybenzone, making it a less desirable choice for sensitive skin or children.

Environmental organizations have also flagged oxybenzone and octinoxate for their potential to damage coral reefs and marine life. As reported by the National Geographic, locations such as Hawaii and Key West have banned sunscreens containing these compounds to help protect fragile ocean ecosystems. Dermatologists and the Environmental Working Group (EWG) recommend choosing mineral-based sunscreens with zinc oxide or titanium dioxide as safer alternatives. These ingredients offer broad-spectrum protection without the environmental or health risks associated with certain chemical filters, making them the preferred option for conscientious consumers.

6. Look for Water Resistance

6. Look for Water Resistance

Water resistance is a critical feature to consider when choosing a sunscreen, especially for outdoor activities involving swimming, sweating, or sports. The term “water-resistant” on a sunscreen label means the product maintains its SPF protection for a specified period—either 40 or 80 minutes—while you are in the water or perspiring. According to the FDA, no sunscreen is truly waterproof or sweatproof, and brands are prohibited from making such claims. Instead, the label should clearly state the duration of water resistance.

For beach days, pool outings, or intense workouts, dermatologists recommend selecting a sunscreen labeled “water-resistant (40 minutes)” or “water-resistant (80 minutes)” for reliable protection. Even with these products, it is crucial to reapply sunscreen after swimming, towel drying, or heavy sweating. The American Academy of Dermatology emphasizes reapplying every two hours as well, regardless of water exposure. By choosing a water-resistant formula and following reapplication guidelines, you can help ensure continuous protection against sunburn and long-term skin damage during all your outdoor activities.

7. Consider Sensitive Skin Formulas

7. Consider Sensitive Skin Formulas

Individuals with sensitive skin should seek sunscreens specifically labeled as “hypoallergenic” and “fragrance-free.” Regular sunscreen formulas often contain added fragrances, preservatives, or certain chemical filters that can trigger irritation, redness, or allergic reactions. According to the American Academy of Dermatology, mineral-based sunscreens using zinc oxide or titanium dioxide are less likely to cause sensitivity and are typically recommended for those with reactive skin.

Sensitive skin formulas are carefully crafted to minimize harsh additives. In comparison to regular sunscreens, they frequently omit parabens, oxybenzone, and artificial scents. You’ll often find such products labeled as “gentle” or “for sensitive skin” on their packaging. Before fully incorporating a new sunscreen into your routine, dermatologists recommend performing a patch test: apply a small amount to a discreet area, like the inside of your elbow, and wait 24 hours to observe any adverse reactions. If no irritation occurs, the product is likely safe for broader use. For more information on choosing sunscreens for sensitive skin types and reading ingredient labels, consult the National Eczema Association‘s sunscreen guide.

8. Choose Fragrance-Free Options

Fragrances are among the most common causes of irritation and allergic reactions in skincare, including sunscreens. While scented sunscreens may offer a pleasant aroma, the added fragrance chemicals can trigger contact dermatitis, redness, or itching—especially in individuals with sensitive skin, eczema, or allergies. According to the American Academy of Dermatology, fragrance-free sunscreens are preferable for anyone prone to skin sensitivity or for use on children and infants.

When comparing scented and unscented sunscreens, fragrance-free options are formulated without added perfume or masking scents. This significantly lowers the risk of skin irritation and allergic response. While some unscented products may still carry a mild natural scent from their base ingredients, they are unlikely to provoke the same reactions as artificially fragranced varieties. Vulnerable groups—such as children, individuals with atopic dermatitis, or those undergoing dermatological treatments—should always opt for fragrance-free formulas for safer, gentler protection. For further guidance on identifying and avoiding potentially irritating ingredients in sunscreens, consult resources from the Allergy UK, which offers tips for selecting suitable sun protection for sensitive or allergy-prone skin.

9. Be Aware of Expiration Dates

9. Be Aware of Expiration Dates

Sunscreen effectiveness declines over time as the active ingredients break down, reducing their ability to protect against harmful UV radiation. Using expired sunscreen can significantly increase your risk of sunburn, skin damage, and long-term health issues. The FDA requires that all sunscreens retain their original strength for at least three years, but exposure to heat or sunlight can accelerate ingredient degradation, causing potency to wane sooner.

Always check the expiration date printed on the sunscreen bottle before use. If the date is missing or illegible, a good rule of thumb is to discard any sunscreen more than three years old or if you notice changes in color, smell, or texture. Proper storage is essential to maintain effectiveness—keep your sunscreen in a cool, shaded place and avoid leaving it in hot environments like cars or direct sunlight. For more information on sunscreen storage and expiration guidelines, refer to the American Academy of Dermatology. Staying vigilant about expiration dates ensures you’re always protected with a product that works as intended.

10. Mind the Texture and Finish

The texture and finish of a sunscreen can greatly impact how likely you are to use it consistently. Sunscreens come in various forms, including gels, lotions, creams, sprays, and sticks. Gels are lightweight and often preferred for oily or acne-prone skin, as they leave a matte finish and absorb quickly. Lotions and creams are more hydrating, making them ideal for dry or sensitive skin, and are easy to spread over larger areas. Sprays offer quick and convenient application but require careful use to ensure even coverage and adequate protection, as noted by the American Academy of Dermatology.

Texture also affects the finish—whether it is matte, dewy, or leaves a white cast. Mineral sunscreens, for instance, can sometimes leave a visible residue, while chemical sunscreens tend to blend in seamlessly. The best way to find your ideal sunscreen is to try several types and see which texture and finish you enjoy most, as personal preference plays a major role in adherence. For more advice on choosing the right sunscreen format for your lifestyle and skin type, consult the Skin Cancer Foundation.

11. Select Non-Comedogenic Formulas

11. Select Non-Comedogenic Formulas

The term non-comedogenic refers to products specifically formulated not to clog pores, which is vital for individuals with acne-prone or oily skin. Standard sunscreens, especially those that are thick or contain certain oils, can sometimes contribute to breakouts by trapping sweat, bacteria, and sebum, leading to blackheads and pimples. Non-comedogenic sunscreens, on the other hand, are designed with lighter ingredients and avoid pore-blocking substances, making them safer for daily use on breakout-prone skin.

According to the American Academy of Dermatology, choosing non-comedogenic products helps reduce the likelihood of acne flare-ups while still providing essential sun protection. When comparing formulas, look for “non-comedogenic” clearly marked on the label and avoid ingredients like heavy oils, lanolin, or artificial fragrances. Gel-based or water-based sunscreens are often less likely to cause congestion than creamier variants. For those with acne-prone skin, patch test new sunscreens before full application and consult a dermatologist if you’re unsure which products are best. For more guidance and a list of recommended non-comedogenic sunscreens, visit the Healthline guide to acne-friendly sun protection.

12. Prioritize Pediatric-Friendly Formulas

Children’s skin is more delicate and sensitive than that of adults, requiring extra care and attention when choosing sun protection. Pediatric-friendly sunscreens are formulated to minimize irritation and allergic reactions, often avoiding harsh chemicals and unnecessary additives. According to the American Academy of Dermatology, the best sunscreens for kids are those containing mineral-based ingredients like zinc oxide and titanium dioxide, which provide broad-spectrum protection while being gentle on sensitive skin.

Families should look for formulas labeled “tear-free,” “fragrance-free,” and “hypoallergenic” to further reduce the risk of discomfort or rashes. Creams and sticks are preferable over sprays for children, as they allow for more controlled and even application. The Centers for Disease Control and Prevention (CDC) also advises that infants under six months should be kept out of direct sunlight and dressed in protective clothing, reserving sunscreen for small exposed areas. For older children, remember to reapply sunscreen every two hours and after swimming or sweating. Establishing sun-safe habits early helps protect children’s skin now and reduces their long-term risk of skin cancer.

13. Don’t Skip Your Lips

13. Don't Skip Your Lips

The lips are often overlooked when it comes to sun protection, yet they are highly susceptible to UV damage due to their thin, delicate skin and lack of melanin. Prolonged sun exposure can lead to painful burns, chapping, premature aging, and even increase the risk of lip cancers, particularly on the lower lip, as noted by the Skin Cancer Foundation. Regular lip balms typically provide moisture but lack the necessary UV protection to defend against harmful rays.

For effective sun safety, opt for a specialized lip balm with an SPF of 30 or higher. These products are formulated to not only hydrate but also shield the lips from both UVA and UVB rays. Ingredients such as zinc oxide or titanium dioxide are recommended for sensitive lips and provide broad-spectrum coverage. It’s important to reapply lip sunscreen every two hours, and more frequently after eating, drinking, or swimming. For further tips on protecting your lips from sun exposure, explore the American Academy of Dermatology’s recommendations at this resource. Don’t neglect your lips—make SPF lip care a daily habit for complete sun protection.

14. Protect the Eyes and Surrounding Skin

14. Protect the Eyes and Surrounding Skin

The skin around the eyes is among the thinnest and most sensitive on the body, making it particularly vulnerable to sun damage, premature aging, and even skin cancers such as basal cell carcinoma. According to the American Academy of Ophthalmology, UV rays can also contribute to eye conditions like cataracts and macular degeneration if proper protection isn’t used. While regular facial sunscreens offer some defense, they can sometimes cause stinging, irritation, or watery eyes if accidentally applied too close to the lash line or eyelids.

To safely protect this area, look for sunscreens specifically labeled as “eye-safe,” “ophthalmologist-tested,” or “for sensitive skin.” These formulations are less likely to migrate or cause discomfort. Mineral-based sticks or creams containing zinc oxide or titanium dioxide are popular choices because they stay put and are gentle on delicate tissue. When applying, use your ring finger to gently dab a small amount around the orbital bone, avoiding direct contact with the eyes. For additional protection, pair sunscreen with broad-brimmed hats and UV-blocking sunglasses. For more guidance, visit the Skin Cancer Foundation’s eye sun protection guide.

15. Recognize Spray and Stick Sunscreens’ Limitations

15. Recognize Spray and Stick Sunscreens' Limitations

Spray and stick sunscreens offer convenience and portability, but their application methods can affect the level of protection they provide. Sprays are popular for quick coverage and hard-to-reach areas, but it can be difficult to ensure even, adequate application. Windy conditions can disperse the product, and the fine mist may lead to inhalation risks. The FDA cautions users to spray sunscreen onto hands first before applying to the face and to avoid inhaling the aerosol.

Stick sunscreens are mess-free and ideal for small, targeted areas like the nose, ears, and around the eyes. However, their thick consistency can make it challenging to achieve full, even coverage over larger areas. In real-world scenarios, such as beach outings or sports, users often under-apply sprays and sticks compared to lotions, potentially leaving parts of the skin unprotected. To maximize effectiveness, apply spray sunscreen until the skin glistens, then rub it in for uniform coverage. With sticks, make multiple passes over each area and blend well. For more details on proper usage and limitations, consult the American Academy of Dermatology’s sunscreen application tips.

16. Check for Eczema and Allergy Certifications

16. Check for Eczema and Allergy Certifications

For those with eczema, allergies, or highly sensitive skin, choosing sunscreens with specific certifications can make a significant difference in comfort and safety. Organizations like the National Eczema Association (NEA) and Allergy UK offer seals of approval for products rigorously tested to be free of known irritants, fragrances, and harsh preservatives. These certifications signal that a sunscreen is less likely to provoke flare-ups, itching, or allergic reactions, compared to standard products that may contain a broader range of chemicals and additives.

Certified sunscreens are formulated with gentle, non-irritating ingredients—often favoring mineral filters like zinc oxide and titanium dioxide. When comparing with standard sunscreens, these products typically avoid parabens, oxybenzone, and other common triggers. To ensure you’re selecting a safe option, look for the NEA Seal of Acceptance or allergy certification logos directly on the packaging. Carefully review ingredient lists for the absence of fragrances, dyes, and alcohols, which can exacerbate symptoms. For a comprehensive list of recommended sunscreens for sensitive or eczema-prone skin, visit the NEA’s sunscreen directory. Choosing certified products provides peace of mind for those needing extra skin protection.

17. Mind the Price vs. Quality Balance

When selecting sunscreen, it’s natural to weigh the cost against quality. Premium sunscreens often boast advanced ingredients, elegant textures, and specialized formulations, but many store brands offer comparable protection at a fraction of the price. According to Consumer Reports, several affordable, drugstore sunscreens perform just as well—if not better—than more expensive alternatives in terms of UV protection and water resistance. The key is to ensure the product is broad-spectrum, SPF 30 or higher, and suitable for your skin type.

Store brands, which typically meet FDA standards, are often tested alongside premium options and can be a budget-friendly solution for families or frequent users. To maximize value, consider buying larger bottles, looking for multi-packs, or shopping during seasonal promotions. Don’t compromise on safety to save a few dollars; instead, focus on reading ingredient labels and checking for necessary certifications. If you have specific skin concerns, investing in a dermatologist-recommended formula for the face while using a more economical option for the body can balance quality and cost. For more insights on finding effective sunscreens at every price point, visit the Consumer Reports sunscreen guide.

18. Use Enough Product

18. Use Enough Product

Proper sunscreen application is just as important as choosing the right formula. Dermatologists emphasize that most people use far less sunscreen than needed, which significantly reduces its effectiveness. The American Academy of Dermatology recommends applying about one ounce (a shot glass full) of sunscreen to cover the entire body for each application. For the face alone, a nickel-sized dollop is generally sufficient. Under-application—such as a thin layer or quick spritz—can leave skin vulnerable to UV damage.

Common mistakes include missing spots like the ears, back of the neck, tops of the feet, and the part in your hair. Visual cues can help: use enough sunscreen so that it’s visible on the skin before rubbing it in, and don’t forget to reapply every two hours, or immediately after swimming or heavy sweating. For sprays, apply until the skin glistens and rub in for even coverage. According to the CDC, consistent and generous use is key to achieving the level of protection promised on the label. Using the correct quantity ensures you’re fully shielded from harmful UV rays.

19. Reapply Regularly

19. Reapply Regularly

Consistent reapplication is crucial for maintaining sunscreen’s protective benefits throughout the day. Even the most effective sunscreen can lose potency due to sweat, water exposure, or simple absorption into the skin. The American Academy of Dermatology recommends reapplying sunscreen at least every two hours, and immediately after swimming, towel drying, or heavy sweating. Failing to reapply can leave your skin exposed and significantly increase your risk of sunburn and long-term damage.

Activity level plays a significant role in how often you should reapply. For example, if you’re swimming, exercising outdoors, or sweating heavily, sunscreen needs to be reapplied more frequently—even if you’re using a water-resistant formula. In contrast, those in shaded or indoor environments for extended periods may not need to reapply as often, but should still follow the two-hour guideline when exposed to sunlight. Setting phone reminders or keeping a bottle of sunscreen easily accessible in your bag can help you remember. For more practical tips on proper sunscreen use and reapplication, check out this resource from the Centers for Disease Control and Prevention, which reinforces the importance of regular reapplication for optimal sun protection.

20. Watch for White Cast

20. Watch for White Cast

One of the most common complaints about mineral sunscreens is the white cast they can leave on the skin, a result of physical UV filters like zinc oxide and titanium dioxide sitting on the surface and reflecting light. This residue can be particularly noticeable on medium to deep skin tones, sometimes discouraging individuals from consistent use. According to the American Academy of Dermatology, newer formulations have improved their blendability and transparency, but some products may still be more cosmetically elegant than others.

For those concerned about white cast, look for mineral sunscreens labeled “sheer,” “invisible,” or “tinted.” Tinted mineral formulas often use iron oxides, which help blend the product seamlessly into a wider range of skin tones and provide additional protection against visible light. To reduce white residue, warm the sunscreen between your fingers before applying, and take extra time to rub it in thoroughly. For more product comparisons and recommendations tailored to different complexions, visit the Skin Cancer Foundation’s guide for mineral sunscreens on dark skin. Choosing the right sunscreen ensures both effective protection and a comfortable, natural finish.

21. Choose Reef-Safe Formulas

The environmental impact of sunscreen has become an increasing concern, especially for those who swim in oceans or visit coral reefs. Certain chemical ingredients, most notably oxybenzone and octinoxate, have been shown to contribute to coral bleaching and harm marine ecosystems, according to research cited by the National Geographic. As a result, destinations like Hawaii and parts of the Caribbean have enacted bans on sunscreens containing these harmful chemicals to protect their reefs.

“Reef-safe” or “reef-friendly” sunscreens typically avoid oxybenzone, octinoxate, and other ingredients like octocrylene and certain parabens. Instead, they rely on non-nano mineral filters such as zinc oxide and titanium dioxide, which are less likely to damage marine life. However, the terms “reef-safe” and “reef-friendly” are not regulated, so consumers should always check ingredient labels for assurance. For environmentally conscious sun protection, choose mineral-based sunscreens clearly free from prohibited chemicals. For more detailed guidance and a list of recommended reef-safe products, visit the Environmental Working Group’s reef-safe sunscreen guide. Choosing eco-friendly formulas protects both your skin and our precious aquatic environments.

22. Consider Tinted Sunscreens

Tinted sunscreens offer unique advantages by combining broad-spectrum UV protection with cosmetic coverage and additional defense against visible light. Unlike untinted formulas, which rely solely on mineral or chemical filters to block UVA and UVB rays, tinted sunscreens often contain iron oxides that protect against high-energy visible (HEV) light—an emerging concern in skin aging and pigmentation, especially for individuals with melasma or darker skin tones. The American Academy of Dermatology recommends tinted sunscreens for those seeking to reduce hyperpigmentation and even out complexion.

In comparison, untinted sunscreens provide excellent UV protection but offer no coverage for skin imperfections or visible light. Tinted options can double as lightweight foundation, offering a natural glow and minimizing redness, blemishes, or uneven skin tone. When applying, use a generous amount to ensure both cosmetic and sun-blocking benefits, and blend thoroughly for a seamless finish. Reapply every two hours, as you would with any sunscreen. For more information and a list of dermatologist-recommended tinted sunscreens, explore the Skin Cancer Foundation’s guide to tinted sunscreens. Tinted sunscreens are a practical, stylish way to elevate your daily sun protection routine.

23. Look for Antioxidant Boosts

Some modern sunscreens are formulated with added antioxidants such as vitamins C and E, green tea extract, or niacinamide. These ingredients provide an extra layer of defense by neutralizing free radicals generated by UV exposure, which can accelerate skin aging and increase the risk of cellular damage. According to the American Academy of Dermatology, antioxidants complement the protective effects of sunscreen by reducing oxidative stress and inflammation caused by sunlight and environmental pollutants.

Basic sunscreens offer reliable UV protection, but those enhanced with antioxidants may further guard against premature aging and support overall skin health. When comparing products, look for labels mentioning antioxidants or “broad-spectrum protection with antioxidant defense.” For optimal results, apply antioxidant-enriched sunscreen to clean skin every morning, allowing it to absorb fully before layering makeup or other skincare products. For additional protection, pair your sunscreen with antioxidant serums or moisturizers. While these boosted formulas are beneficial, they should not replace other sun-safe behaviors, such as seeking shade and wearing protective clothing. To learn more about the benefits and science behind antioxidants in sunscreen, visit the Dermatology Times’ overview of antioxidants in sun care.

24. Understand the Role of PA Ratings

The PA rating system, originally developed in Japan and now widely used in Asia and beyond, measures a sunscreen’s level of protection against UVA rays, which are responsible for skin aging and long-term cellular damage. Unlike SPF, which only indicates protection against UVB rays (the primary cause of sunburn), the PA system uses a scale of “+” signs to denote the degree of UVA defense—ranging from PA+ (some protection) to PA++++ (very high protection). According to The Skin Cancer Foundation, both UVA and UVB protection are essential for comprehensive sun safety.

When comparing products, SPF tells you how long you’re protected from burning, while PA ratings indicate how well your skin is shielded from the aging and deep-penetrating effects of UVA rays. Many global sunscreens, especially those from Europe and Asia, display both SPF and PA ratings, providing clearer guidance for consumers seeking broad-spectrum coverage. If purchasing international products, look for a high PA rating (PA+++ or PA++++) in addition to a minimum SPF 30. For a deeper dive into reading these labels and understanding international sunscreen standards, refer to this Healthline guide to PA ratings in sunscreen.

25. Verify Pediatrician or Dermatologist Endorsements

25. Verify Pediatrician or Dermatologist Endorsements

Professional endorsements from pediatricians or dermatologists provide valuable reassurance that a sunscreen has undergone rigorous evaluation for safety and efficacy. These endorsements differ from generic marketing claims like “doctor-recommended” or “trusted by experts,” which may not be supported by formal review or clinical testing. According to the American Academy of Dermatology, products bearing endorsements from reputable medical organizations or professionals are more likely to meet quality and safety standards, especially for sensitive populations such as children or individuals with skin conditions.

To verify a product’s endorsement, look for seals or logos from recognized organizations, such as the American Academy of Dermatology (AAD) or the National Eczema Association (NEA), directly on the packaging. Some sunscreens will also reference specific pediatrician or dermatologist involvement in their testing process or formulation. Be cautious of vague claims not backed by verifiable sources. When in doubt, check the official websites of professional organizations to confirm whether a particular product is genuinely endorsed. For further guidance on finding professionally recommended sunscreens, consult the AAD’s trusted sunscreen selection resource or ask your healthcare provider for personalized recommendations.

26. Consider Your Primary Activities

26. Consider Your Primary Activities

Your daily activities and lifestyle play a significant role in determining the most suitable sunscreen for your needs. Sunscreens designed for sports or outdoor adventures are typically water-resistant, sweat-proof, and formulated to stay in place during vigorous movement. These products often come in stick or spray forms for quick, mess-free application and are ideal for athletes, runners, or anyone spending extended time outdoors. For beach outings or swimming, opt for broad-spectrum sunscreens labeled “water-resistant (80 minutes)” and ensure regular reapplication, as recommended by the American Academy of Dermatology.

For everyday use, especially for those primarily indoors or commuting, lightweight lotions or creams that blend well under makeup may be more appropriate. Consider non-comedogenic and fragrance-free formulas if you have sensitive or acne-prone skin. If you’ll be exposed to visible light (from screens or through windows), tinted sunscreens offer added protection. Tailoring your sunscreen choice to your routine helps ensure you’re both comfortable and adequately protected. For more practical advice and product suggestions for specific activities, consult the Skin Cancer Foundation’s sunscreen FAQ, which addresses sun safety for every lifestyle.

27. Be Cautious with DIY Sunscreens

The popularity of natural skincare has led some people to experiment with making their own sunscreens at home. However, homemade sunscreens pose significant risks and are not recommended by dermatologists or public health organizations. Unlike regulated commercial products, DIY sunscreens lack standardized testing for SPF and UVA/UVB protection, making it impossible to guarantee their effectiveness. According to the FDA, sunscreens must undergo rigorous evaluation and meet strict labeling requirements to ensure safety and efficacy—standards homemade recipes cannot match.

Common DIY sunscreen ingredients, such as coconut oil, shea butter, or essential oils, offer little to no proven sun protection and can give a false sense of security. In comparison, regulated sunscreens are formulated with scientifically validated active ingredients and are subject to quality control measures. Relying on untested homemade recipes can lead to serious sunburn, premature aging, and increased risk of skin cancer. For comprehensive protection, always choose a broad-spectrum, FDA-approved sunscreen from a reputable manufacturer. For more information on sunscreen safety and the dangers of DIY alternatives, visit the American Academy of Dermatology’s warning on DIY sunscreens.

28. Notice Packaging for Portability

Packaging plays a pivotal role in how likely you are to reapply sunscreen throughout the day, especially when you’re on the go. Portable, user-friendly packaging—such as travel-sized tubes, sticks, or compact sprays—makes it easier to keep sunscreen handy in your bag, car, or pocket. According to the Skin Cancer Foundation, the convenience of smaller packaging increases the chances that you’ll remember to reapply, which is essential for sustained protection.

Travel-sized sunscreens (usually under 3.4 ounces or 100 mL) are especially useful for air travel, complying with TSA regulations and fitting easily into purses, backpacks, or even the glove compartment. Sticks and roll-ons are ideal for targeted touch-ups, while mini sprays cover larger areas quickly. When comparing packaging options, consider your typical activities and storage preferences. To avoid leaks, choose products with secure caps and sturdy materials. For best results, stash sunscreen in multiple locations—such as your gym bag, office desk, or stroller—so you’re never caught without it.

Tanning oils with low SPF—often SPF 15 or below—pose significant risks to your skin’s health. These products are formulated to intensify sun exposure, promoting a darker tan but offering minimal protection against harmful UV rays. According to the Skin Cancer Foundation, using low-SPF tanning oils can result in severe sunburn, accelerated skin aging, and a heightened risk of skin cancer, including melanoma. In comparison, sunscreens with SPF 30 or higher are proven to block a greater percentage of UVB rays, dramatically reducing the chances of DNA damage and long-term consequences.

While the allure of a quick tan may be tempting, the outcomes can include painful burns, uneven skin tone, premature wrinkles, and dangerous cumulative UV exposure. High-SPF sunscreens, especially broad-spectrum formulas, provide effective protection without sacrificing your skin’s appearance or safety. If you desire a sun-kissed look, consider self-tanning products that do not involve UV radiation. For more information on the dangers of tanning oils and how to make safer sun protection choices, consult the American Academy of Dermatology’s tanning prevention guide. Prioritizing high-SPF sunscreens is a smart step for lifelong skin health.

Your skin type plays a crucial role in determining the best sunscreen for your daily routine. Oily or acne-prone skin often benefits from lightweight, gel-based, or water-based sunscreens labeled “oil-free” and “non-comedogenic,” which help prevent clogged pores and breakouts. Look for matte finishes or ingredients like silica for shine control. Dry skin, on the other hand, may require creamier, moisturizing formulas that contain hydrating ingredients such as hyaluronic acid, glycerin, or ceramides, which help soothe and prevent flakiness.

Combination skin can be more challenging, but selecting a balanced sunscreen—neither too greasy nor too drying—ensures comfort and protection. Consider layering a hydrating sunscreen on dry areas and a mattifying formula on oilier zones, or opt for multi-benefit products. Sensitive skin types should prioritize mineral sunscreens with zinc oxide or titanium dioxide, as these are less likely to cause irritation. For more tailored tips and product recommendations, visit the American Academy of Dermatology’s sunscreen selection guide. Matching sunscreen features to your skin type not only improves comfort and appearance but also increases the likelihood of consistent, effective use for optimal sun safety.

31. Don’t Rely on Makeup SPF Alone

Many foundations, tinted moisturizers, and powders now include SPF, but relying solely on makeup with sun protection is not sufficient for effective UV defense. According to the American Academy of Dermatology, the SPF in makeup is often much lower than what is recommended for daily use and is rarely applied in the thick, even layer required to achieve the labeled sun protection. In real-world scenarios, most people use only a fraction of the amount of makeup necessary to reach the advertised SPF level, leaving skin exposed to harmful rays.

Dedicated sunscreens are formulated to provide reliable, broad-spectrum protection and are tested for efficacy at the concentrations recommended by dermatologists. For optimal coverage, apply a broad-spectrum sunscreen (SPF 30 or higher) as the last step in your skincare routine and allow it to fully absorb before layering makeup on top. This ensures consistent defense across all areas of the face, including spots that makeup might miss. For touch-ups throughout the day, consider using a powder or spray sunscreen in addition to your makeup. For more layering tips, visit the Skin Cancer Foundation’s advice on SPF in makeup.

32. Use Sunscreen Year-Round

32. Use Sunscreen Year-Round

Many people mistakenly believe sunscreen is only necessary during the summer, but UV exposure occurs throughout the year—even on cloudy, cold, or snowy days. Up to 80% of UV rays can penetrate clouds, and surfaces like snow, sand, and water reflect sunlight, increasing the risk of skin damage. According to the American Academy of Dermatology, winter sports enthusiasts are especially vulnerable, as UV exposure intensifies at higher altitudes and is magnified by snow reflection.

While summer brings higher UV indexes and more direct sun, winter risks include prolonged outdoor activities, such as skiing or hiking, without adequate protection. Year-round habits should include applying a broad-spectrum sunscreen with SPF 30 or higher to all exposed skin—face, neck, ears, and hands—regardless of the season. Reapply every two hours when outdoors, and complement sunscreen use with protective clothing and sunglasses. For more tips on staying protected no matter the weather, visit the CDC’s sun safety recommendations. Consistent, year-round sunscreen use is essential for preventing premature aging, sunburn, and skin cancer.

33. Beware of Spray Inhalation Risks

33. Beware of Spray Inhalation Risks

Spray sunscreens offer convenience and speed, but they come with the potential hazard of inhaling fine particles during application. The U.S. Food and Drug Administration (FDA) has raised concerns about the possibility of respiratory irritation and unknown long-term effects, particularly for children and individuals with asthma or other respiratory conditions. In contrast, creams and lotions are applied directly to the skin, eliminating the risk of airborne particles and ensuring more controlled coverage.

To minimize inhalation risks when using spray sunscreens, avoid spraying near the face or mouth and do not use sprays in enclosed or windy areas. Instead, spray the sunscreen onto your hands first, then rub it onto your face and other sensitive areas. Always supervise children during application and encourage them to look away or hold their breath if spraying is necessary. For more guidelines on safe use, consult the American Academy of Dermatology’s sunscreen application tips. While spray sunscreens can be effective when used properly, taking precautions ensures protection without compromising respiratory health.

34. Watch for Claims Like ‘Sport’ or ‘Baby’

34. Watch for Claims Like 'Sport' or 'Baby'

Marketing labels such as “Sport,” “Baby,” or “Sensitive” are commonly used to attract consumers, but it’s important not to rely solely on these terms when selecting a sunscreen. While products labeled “Sport” often tout water and sweat resistance, the FDA mandates that all water resistance claims be substantiated, regardless of the product’s branding. “Baby” sunscreens may imply added gentleness, but their actual formulations can vary significantly between brands.

True formulation differences may exist, such as the use of mineral-only filters (zinc oxide or titanium dioxide) in many “baby” or “sensitive” products, which are less likely to cause irritation. However, not all products labeled for babies or sports are free from fragrances, parabens, or other potential irritants. To ensure the sunscreen’s safety and efficacy, always read the ingredient list and look for key features such as “broad-spectrum,” “SPF 30 or higher,” and hypoallergenic claims. For additional assurance, check for endorsements from reputable organizations like the American Academy of Dermatology. Informed label reading is essential to find the best match for your skin’s needs.

35. Consider Sunscreen Powders

35. Consider Sunscreen Powders

Sunscreen powders have gained popularity for their convenience and ease of reapplication, especially over makeup throughout the day. These products are typically mineral-based, using ingredients like zinc oxide or titanium dioxide to provide broad-spectrum protection. One of the main benefits of powder sunscreens is their lightweight, non-greasy finish, which helps control shine and is well-suited for oily or combination skin types. They are also portable, making touch-ups simple while on the go.

However, sunscreen powders have limitations. According to the Skin Cancer Foundation, it can be difficult to apply a sufficient and even layer of powder to achieve the SPF indicated on the packaging. In comparison, liquid or cream sunscreens are easier to apply generously and ensure full coverage, making them preferable for initial application. To use powders effectively, apply them as a convenient supplement for midday touch-ups, not as your sole form of sun protection. For best results, start with a traditional sunscreen in the morning and use powder sunscreen throughout the day to maintain coverage, especially on the face and scalp. For more on safe and effective sunscreen powders, visit the American Academy of Dermatology’s guide.

36. Be Wary of ‘Natural’ and ‘Organic’ Labels

36. Be Wary of 'Natural' and 'Organic' Labels

The terms “natural” and “organic” are often used on sunscreen packaging to appeal to health-conscious consumers, but these labels are not strictly regulated by the FDA in the context of sun protection products. According to the FDA, there is no formal definition for “natural” in cosmetics, and “organic” only holds meaning if the product is certified by the U.S. Department of Agriculture (USDA). This means products labeled as “natural” or “organic” may still contain synthetic ingredients or lack proven efficacy for UV protection.

When comparing efficacy, mineral sunscreens using zinc oxide or titanium dioxide—sometimes advertised as “natural”—can offer excellent broad-spectrum protection if formulated and tested properly. However, some “natural” or “organic” sunscreens may rely on plant oils or herbal extracts, which do not provide sufficient UV defense. To make evidence-based choices, look for products with verified SPF ratings, broad-spectrum claims, and recognized endorsements from organizations like the American Academy of Dermatology. Always read ingredient lists and prioritize products with clinical testing and regulatory approval over loosely defined marketing terms.

37. Check Compatibility with Other Skincare

37. Check Compatibility with Other Skincare

Sunscreen is most effective when it works harmoniously with other skincare products, such as moisturizers and makeup. The order of application and compatibility of formulas can impact absorption, finish, and protection. According to the American Academy of Dermatology, sunscreen should be applied as the final step in your morning skincare routine, after serums and moisturizers but before makeup. This ensures it forms a protective barrier without being diluted or disturbed by subsequent products.

Water-based or gel moisturizers layer well under most sunscreens, while oil-rich creams may cause some mineral sunscreens to pill or separate. For makeup, silicone-based or lightweight foundations generally blend smoothly over sunscreen. To avoid clumping, allow each layer to fully absorb before applying the next and pat, rather than rub, makeup onto the skin. For added sun defense, consider setting your makeup with a powder or spray sunscreen. If you’re using active treatments like retinoids or exfoliating acids, mineral sunscreens are less likely to cause further irritation. For more on integrating sunscreen into your daily skincare routine, visit the Healthline guide to layering skincare.

38. Understand UVA Aging Risks

38. Understand UVA Aging Risks

UVA rays penetrate the skin more deeply than UVB rays, playing a major role in premature skin aging, including wrinkles, sagging, age spots, and loss of elasticity. Unlike UVB, which is primarily responsible for sunburn, UVA exposure is constant throughout the year and can pass through clouds and glass, making protection essential even indoors or on overcast days. According to the Skin Cancer Foundation, UVA rays account for up to 95% of the UV radiation reaching the Earth’s surface and are a leading cause of photoaging.

When comparing UVB and UVA, UVB’s effect is more immediate and visible, while UVA’s damage accumulates over time, often presenting as fine lines, uneven tone, and rough texture. To protect against aging, select a sunscreen labeled “broad-spectrum,” which guards against both UVA and UVB. For enhanced anti-aging benefits, consider formulas with added antioxidants or DNA-repair enzymes. Daily, year-round application is key, as UVA rays penetrate windows and contribute to cumulative skin aging. For more information on UVA, photoaging, and choosing the best sunscreen for anti-aging, consult the American Academy of Dermatology’s UVA/UVB guide.

39. Watch for Allergic Reactions

While sunscreen is essential for skin health, some individuals may experience allergic reactions or sensitivities to certain ingredients. Common signs of a sunscreen allergy include redness, itching, swelling, rash, or hives shortly after application. In more severe cases, blisters or peeling may occur. According to the American Academy of Dermatology, chemical filters like oxybenzone, avobenzone, and fragrances are frequent triggers, whereas mineral-based sunscreens with zinc oxide or titanium dioxide are less likely to cause irritation.

Patch testing is a helpful strategy to prevent widespread reactions: apply a small amount of the sunscreen to a discreet area, such as the inside of your forearm, and wait 24 to 48 hours. If no symptoms develop, the product is generally safe for broader use. Those with a history of allergies or sensitive skin should seek sunscreens labeled “hypoallergenic,” “fragrance-free,” or those with eczema or allergy certifications. If you experience an adverse reaction, discontinue use immediately and consult a healthcare provider or dermatologist. For more information on sunscreen allergies and ingredient safety, visit the WebMD sunscreen allergy resource.

40. Don’t Skip Application on Cloudy Days

It’s a common misconception that sunscreen isn’t necessary on cloudy or overcast days, but up to 80% of ultraviolet (UV) rays can penetrate through clouds and reach your skin. According to the Skin Cancer Foundation, this hidden exposure can increase your risk of sunburn and contribute to long-term skin damage, including premature aging and skin cancer. Sunburn can still occur even when the sun isn’t visible, and people often underestimate the need for protection during milder weather, leading to unexpected burns.

Comparatively, UV risk on cloudy days remains significant, especially during midday hours or at higher altitudes. The danger lies in the fact that you may not feel hot or see the sun, so you’re less likely to notice overexposure. To develop safe habits, apply a broad-spectrum sunscreen with SPF 30 or higher to all exposed skin every day, regardless of the weather. Make sunscreen application a part of your morning routine, just like brushing your teeth. For more information on UV exposure in different weather conditions, visit the CDC’s sun safety resource. All-weather application ensures consistent, long-term skin protection.

41. Note Country-Specific Regulations

Sunscreen standards and regulations differ significantly around the world, which can impact the types of products available and their labeled protection. In the United States, the FDA classifies sunscreens as over-the-counter (OTC) drugs, requiring rigorous testing for SPF and water resistance, but currently approves a limited range of active ingredients. In contrast, the European Union allows a broader array of UV filters and mandates robust UVA protection, often ensuring more comprehensive broad-spectrum coverage. The EU also uses the UVA circle logo and additional labeling systems that may not appear on US products.

For international travelers, it’s important to be aware of these differences. A sunscreen purchased abroad may have unfamiliar ingredients or different SPF/UVA labeling conventions. When traveling, opt for products with clear broad-spectrum claims and, if possible, check for local regulatory seals or endorsements. If you have sensitive skin or allergies, review ingredient lists carefully, as filters approved in one country may not be present or tested in another. For more guidance on choosing and using sunscreen across borders, consult the Skin Cancer Foundation’s overview of global sunscreen standards.

42. Choose Suitable Sunscreen for Hairy Areas

42. Choose Suitable Sunscreen for Hairy Areas

Applying sunscreen to hairy areas—such as the scalp, arms, legs, or chest—presents unique challenges, as thick creams can be difficult to spread and may leave a greasy residue or clump in hair. The scalp, in particular, is highly vulnerable to sunburn and skin cancer, especially where hair is thinning or parted. According to the Skin Cancer Foundation, using the right sunscreen type is crucial to ensure adequate protection without discomfort.

Spray or powder sunscreens are often the best choices for hairy areas, as they are lightweight, easy to apply evenly, and less likely to mat hair. For the scalp, sunscreen sprays or brush-on powders can be applied along the part or directly onto exposed skin. Gel-based sunscreens are also less sticky and absorb quickly, making them suitable for areas with dense body hair. When possible, wear a wide-brimmed hat or cap for additional protection. For body hair, rub in the sunscreen thoroughly to ensure it reaches the skin beneath. For more practical advice and product suggestions for hairy areas, visit the American Academy of Dermatology’s scalp and hair sun safety guide.

43. Be Mindful of Staining Clothing

Certain sunscreen ingredients, especially those found in chemical formulas, can cause unsightly stains on clothing. Avobenzone is a common culprit, as it can react with minerals in water (like iron) to create orange or yellow discoloration, particularly on light fabrics. According to the Consumer Reports, mineral-based sunscreens with zinc oxide or titanium dioxide are less likely to stain, but their thicker texture may still leave white marks if not thoroughly rubbed in.

To minimize the risk of stains, allow sunscreen to fully absorb and dry before dressing. Opt for fragrance-free, mineral-based sunscreens if staining is a frequent issue, as these are usually less oily and less likely to interact with fabrics. When using sprays or lotions, apply them generously and wait a few minutes before putting on clothes, especially swimwear or light-colored garments. If stains occur, pretreat them promptly with a stain remover or a mixture of dish soap and baking soda before laundering. For more tips on preventing and removing sunscreen marks, consult the Good Housekeeping sunscreen stain removal guide.

44. Check for Alcohol Content

44. Check for Alcohol Content
A close-up of a sunscreen bottle’s ingredient label highlights alcohol content, emphasizing its potential to cause dry skin. | Generated by Google Gemini

Alcohol is often included in sunscreen formulations to help the product dry quickly, feel lightweight, and improve absorption. However, certain types of alcohol, such as denatured alcohol (alcohol denat.), can strip the skin’s natural oils and lead to dryness, irritation, or flaking—especially in individuals with sensitive or dry skin. According to the American Academy of Dermatology, frequent use of alcohol-heavy products may exacerbate conditions like eczema or rosacea.

When comparing sunscreens, sprays and gels often contain higher amounts of alcohol to ensure quick drying and a matte finish, which some people with oily skin may prefer. Creams and lotions, on the other hand, are generally lower in alcohol and provide more moisture. For those with sensitive, dry, or allergy-prone skin, it is best to choose formulas labeled “alcohol-free” or to carefully check ingredients for ethanol, denatured alcohol, or isopropyl alcohol. Instead, look for hydrating sunscreens containing glycerin, hyaluronic acid, or ceramides. For more information on how alcohol affects skin and tips for choosing the right sunscreen, visit the Healthline guide to alcohol in skincare.

45. Watch for Nanoparticles in Mineral Sunscreens

Mineral sunscreens often use zinc oxide or titanium dioxide as active ingredients, and these are sometimes formulated using nanoparticles—ultra-fine particles designed to improve spreadability and reduce the visible white cast. While nanoparticles make sunscreens more cosmetically elegant, their safety has been a topic of debate. According to the U.S. Food and Drug Administration (FDA), current research suggests that nanoparticles in sunscreen do not penetrate healthy skin, remaining on the surface and providing effective UV protection without systemic absorption.

When comparing traditional (non-nano) mineral sunscreens with nano formulas, non-nano products may leave a more noticeable white residue but are often preferred by those seeking the “most natural” option. Nano formulas, on the other hand, feel lighter and blend more easily, making them suitable for a wider range of skin tones. Recent safety reviews by the American Cancer Society and Australia’s TGA confirm that nanoparticles in sunscreens are considered safe for topical use. If you have concerns, check product labels for “non-nano” designations or consult with your dermatologist for personalized guidance.

46. Use Sunscreen Under Makeup

46. Use Sunscreen Under Makeup

Applying sunscreen beneath makeup is a fundamental step in any effective skincare routine. Sunscreen should always be the last step of your skincare regimen—after moisturizer but before foundation or other makeup products. According to the American Academy of Dermatology, this order ensures that the sunscreen creates a uniform, protective barrier without being diluted or disrupted by subsequent products.

Routines can vary: some prefer lightweight, fluid sunscreens that absorb quickly and don’t interfere with makeup application, while others opt for hydrating formulas that double as a primer. Silicone-based sunscreens often work well under makeup because they create a smooth, matte canvas. To maximize protection, let each layer of skincare fully absorb before applying makeup, and use gentle patting motions instead of rubbing to avoid disturbing the sunscreen. For touch-ups throughout the day, consider using a powder or spray sunscreen specifically formulated for use over makeup. For more on layering techniques and product recommendations, visit the Healthline guide to sunscreen and makeup. Proper layering ensures both UV defense and a flawless finish.

47. Seek Out Non-Greasy Formulas

47. Seek Out Non-Greasy Formulas

Non-greasy sunscreens are designed to absorb quickly without leaving a shiny, heavy, or oily residue on the skin. These formulas often use lightweight, water-based, or gel-like ingredients to provide a matte finish, making them especially appealing for those with oily or acne-prone skin. In contrast, traditional or oil-rich sunscreens may feel thick, sticky, or leave a visible sheen—factors that can deter consistent use, particularly in hot or humid environments.

In oily or humid climates, sweat and excess sebum can exacerbate the feeling of heaviness, making non-greasy sunscreens a practical choice for comfort and adherence. According to the American Academy of Dermatology, look for labels such as “oil-free,” “matte,” “dry-touch,” or “non-comedogenic.” Gel or fluid-based mineral sunscreens with zinc oxide or titanium dioxide are excellent options. For those prone to breakouts, avoid ingredients like mineral oil or lanolin. For more tips and product suggestions tailored to oily or humid conditions, see Healthline’s guide to sunscreens for oily skin. Non-greasy formulas support both skin health and daily sun safety.

48. Test New Sunscreens Before Full Use

Patch testing new sunscreens is a proactive step to prevent adverse skin reactions, especially if you have sensitive skin or a history of allergies. Even dermatologist-recommended products can trigger unexpected irritation or allergic responses in some individuals. Signs of a reaction may include redness, itching, swelling, hives, or even blistering—symptoms that can occur within minutes or develop over several hours. Real-world examples include individuals who develop contact dermatitis from chemical filters or fragrances, or experience stinging from alcohol-based sprays, as highlighted by the American Academy of Dermatology.

To patch test a new sunscreen, apply a small amount to a discreet area, such as the inside of your forearm or behind your ear. Wait 24 to 48 hours, monitoring for any signs of irritation or discomfort. If the area remains clear, the product is likely safe for broader use. Best practices also include testing one product at a time and avoiding application to broken or irritated skin. For those with a history of eczema or allergies, look for sunscreens labeled “hypoallergenic” or with certifications from organizations like the National Eczema Association. For additional guidance on patch testing and skin safety, visit this National Eczema Association resource.

49. Remember Sunscreen for All Skin Tones

A common misconception is that individuals with darker skin do not need sunscreen, but this is far from the truth. While higher melanin levels do offer some natural protection against UV rays, no skin tone is immune to sunburn, photoaging, or skin cancer. In fact, people of color are often diagnosed with skin cancer at later, more dangerous stages, leading to poorer outcomes and higher mortality rates, as highlighted by the Skin Cancer Foundation.

Health disparities in awareness and access to sun protection contribute to these risks. Sunscreen is essential for everyone, regardless of complexion, to prevent hyperpigmentation, melasma, and cumulative sun damage. Inclusive protection means choosing sunscreens that work well for all skin tones—tinted mineral formulas or newer sheer mineral options can help minimize white cast on deeper complexions. The American Academy of Dermatology offers advice on selecting effective, cosmetically elegant products for darker skin. Promoting universal sunscreen use and education helps close the gap in skin cancer outcomes and ensures healthy, protected skin for all.
