Top Outrageous TikTok Health Hacks (and Whether They Actually Work)

1. Chlorophyll Water for Clear Skin

One of TikTok’s most viral health hacks involves adding liquid chlorophyll—often a bright green supplement—to water, with the promise of achieving clear, glowing skin. Proponents claim that drinking chlorophyll detoxifies the body, reduces acne, and boosts overall skin health. The biological rationale is that chlorophyll, the pigment responsible for plants’ green color, possesses antioxidant and anti-inflammatory properties. Some users share dramatic before-and-after videos showing reduced breakouts and a brighter complexion within weeks.

However, experts urge caution. While limited studies suggest topical chlorophyll may help heal wounds and reduce acne, the benefits of ingesting it are less certain. According to Medical News Today, there is minimal scientific evidence supporting chlorophyll water as a miracle cure for acne or other skin issues. Some individuals may also experience side effects like digestive upset or allergic reactions.

Practical advice: If you’re considering chlorophyll water, consult a healthcare provider first. Focus instead on proven skin-health habits such as proper hydration, gentle cleansing, and balanced nutrition. Remember, what you see on TikTok often lacks the scrutiny of real scientific validation.

2. Dry Scooping Pre-Workout Powders

The “dry scooping” craze—where users gulp down pre-workout powder straight, without mixing with water—has exploded on TikTok. Believers claim this technique delivers a faster, more intense energy rush, resulting in better workouts. However, this method poses serious cardiovascular risks. Pre-workout powders are highly concentrated stimulants, often packed with caffeine and other energy-boosting ingredients. Consuming them without dilution can lead to rapid absorption, overwhelming the body’s systems.

Medical professionals warn that dry scooping can cause heart palpitations, elevated blood pressure, arrhythmias, and even heart attacks, especially in those sensitive to stimulants. A case detailed by the Healthline reported a 20-year-old experiencing a heart attack after dry scooping before exercise. In contrast, the standard usage—mixing powder with water—dilutes these ingredients, allowing for slower, safer absorption and reducing the risk of choking or aspiration.

Safety pointers: Always follow the manufacturer’s directions and never exceed recommended dosages. If you feel shaky, dizzy, or short of breath, stop immediately and seek medical attention. The risks of dry scooping far outweigh any perceived benefits, and the trend can be especially dangerous for teens and those with underlying heart conditions.

3. Garlic Cloves in the Nose for Congestion

One of the more eye-watering TikTok trends involves stuffing raw garlic cloves into your nostrils to “clear out” nasal congestion. Videos of users pulling out garlic and experiencing a sudden flow of mucus have sparked viral curiosity. The claim is that garlic’s natural compounds—particularly allicin—can reduce inflammation and help decongest sinuses. However, the actual mechanism is misleading: the mucus seen is often a rebound effect from blocking the nasal passage, not a sign of healing.

ENT specialists strongly warn against this hack. Inserting foreign objects like garlic can irritate the sensitive nasal lining, cause burns, trigger allergic reactions, or even lead to infection or airway obstruction. The Cleveland Clinic explicitly advises against this viral practice.

Safer alternatives: Use saline nasal sprays, humidifiers, or over-the-counter decongestants as recommended by healthcare professionals. Steam inhalation and staying hydrated are proven, gentle remedies for congestion. When in doubt, consult an expert rather than experimenting with risky home “hacks” seen online.

4. DIY Mole Removal with Apple Cider Vinegar

A particularly concerning TikTok trend promotes using apple cider vinegar (ACV) to remove moles at home. Advocates claim the acidity of ACV “burns off” moles, leaving behind clear skin. Chemically, ACV contains acetic acid, which can break down skin cells. However, this method is far from safe and carries significant risks.

Dermatologists warn that applying ACV directly to moles can cause chemical burns, severe irritation, infection, and scarring. Even more worrying, improper mole removal can mask the early signs of skin cancer, delaying essential medical intervention. According to the American Academy of Dermatology, only trained professionals should assess and remove suspicious moles.

Real-world cases have resulted in painful wounds and permanent disfigurement, sometimes requiring surgical correction. If a mole changes shape, color, or size—or bleeds—it’s crucial to seek professional evaluation, not a quick TikTok fix. Only a dermatologist can determine whether a mole is benign or requires biopsy. Don’t risk your health or appearance for a social media trend: leave mole removal to the experts.

5. Taping Mouth Shut for Better Sleep

Another TikTok-fueled trend involves taping the mouth shut before bed, with the idea that it encourages nose breathing, reduces snoring, and improves sleep quality. The physiological basis is that nasal breathing can humidify, filter, and regulate airflow more efficiently than mouth breathing. Some users report waking up feeling more rested and less congested after trying mouth taping.

However, experts caution that this hack is not a safe substitute for evidence-based sleep apnea treatments. Mouth taping can be dangerous—especially for individuals with undiagnosed obstructive sleep apnea or other breathing disorders. Blocking the mouth can worsen airflow restriction, increase the risk of suffocation, or exacerbate sleep-related breathing issues. The Sleep Foundation notes there is insufficient clinical evidence to support mouth taping as a sleep aid.

Practical evaluation: If you struggle with snoring or poor sleep, consult a sleep specialist. Proven treatments such as CPAP therapy, weight management, and positional therapy are far safer and more effective. TikTok trends may spark curiosity, but your nighttime breathing is not worth the gamble.

6. Lettuce Water for Sleep

Among TikTok’s more whimsical health hacks is the “lettuce water” trend, where users steep lettuce leaves in hot water and drink the resulting liquid to fall asleep faster. The theory is that lettuce—particularly varieties like romaine—contains lactucarium, a milky substance sometimes called “lettuce opium” for its supposed sedative effects. Videos claim this simple remedy brings on drowsiness within minutes.

However, scientific support is thin. While lettuce does contain certain compounds, including lactucin and lactucopicrin, their concentration in a cup of lettuce water is likely too low to make a noticeable difference. A study published in the National Institutes of Health database notes potential sedative properties in concentrated extracts, but not in the quantities found in a home brew. By contrast, herbal teas such as chamomile or valerian root have more established reputations for promoting relaxation.

For better sleep, evidence-based strategies—like maintaining a consistent sleep schedule, limiting screen time before bed, and creating a calm environment—are far more effective. While sipping lettuce water is unlikely to harm you, don’t expect it to be a miracle cure for insomnia.

7. Oil Pulling for Oral Detox

Oil pulling—swishing coconut or sesame oil in the mouth for up to 20 minutes—has found new life on TikTok as a supposed “oral detox” hack. Advocates claim this ancient practice draws out toxins, whitens teeth, and improves gum health. The mechanism is thought to involve the oil trapping bacteria and debris, which are then spit out, leaving the mouth fresher and healthier.

Scientific studies on oil pulling are limited and results are mixed. According to a review in the Journal of Traditional and Complementary Medicine, oil pulling may reduce oral bacteria and help with bad breath, but it is not superior to conventional mouthwash or brushing. Most evidence remains anecdotal, with little support for its ability to “detox” the body or significantly whiten teeth.

Oral hygiene guidance: For optimal dental health, stick with proven methods: brush twice daily with fluoride toothpaste, floss daily, and see a dentist regularly. Oil pulling is not harmful for most people, but it should never replace standard oral care practices recommended by dental professionals.

8. Sunscreen Contouring

A visually striking but risky TikTok trend is “sunscreen contouring,” where users apply sunscreen only to certain parts of their face—such as the nose bridge, cheekbones, and forehead—to create a naturally contoured look after tanning. The idea is to let the sun “highlight” and “shade” the face, mimicking makeup contour techniques. While this hack may produce temporary visual effects, it poses serious risks.

Dermatologists warn that skipping sunscreen on any part of the face leaves skin vulnerable to harmful UV radiation, increasing the risk of sunburn, premature aging, and skin cancer. According to the Skin Cancer Foundation, there is no safe way to tan, and partial application of sunscreen offers no protection to untreated areas. The cumulative effect of repeated, unprotected sun exposure can lead to long-term skin damage and even melanoma.

Better sun safety: For healthy, glowing skin, apply broad-spectrum SPF 30 or higher evenly to all exposed areas—no exceptions. Use bronzers or makeup for contouring, not the sun. Protecting your skin is always more fashionable than risking your health for a fleeting trend.

9. Rice Water Hair Rinses

Rice water hair rinses have become a viral sensation on TikTok, with users claiming that washing their hair with the starchy water left over from rinsing rice leads to rapid hair growth and extra shine. This practice actually traces back centuries to Asian beauty traditions, particularly among the Yao women of China, who are famous for their long, healthy hair. The appeal is rooted in rice water’s natural nutrients, including amino acids, B vitamins, antioxidants, and minerals.

Some studies and anecdotal reports suggest these nutrients can strengthen hair, reduce friction, and improve elasticity. However, there is limited scientific evidence supporting claims of dramatic hair growth. The Healthline notes that while rice water may condition and temporarily improve hair’s appearance, results will vary and major regrowth should not be expected.

Realistic expectations: Rice water rinses are generally safe and can complement a healthy hair routine, but they are not a miracle cure for hair loss or thinning. For significant hair concerns, consult a dermatologist or trichologist for advice tailored to your individual needs.

10. Lemon Coffee Weight Loss Hack

The “lemon coffee” weight loss hack has swept TikTok, with users mixing lemon juice into black coffee and claiming it melts away belly fat almost overnight. The logic behind this trend is that both lemon and coffee have metabolism-boosting properties: coffee contains caffeine, which can temporarily increase metabolic rate, while lemon is rich in vitamin C and antioxidants.

Despite these modest metabolic effects, there is no scientific evidence supporting the combination as a magic weight loss solution. According to the Cleveland Clinic, drinking lemon coffee won’t burn fat or lead to significant weight loss without other meaningful lifestyle changes. Clinical weight management is far more complex and involves personalized dietary planning, regular physical activity, and behavior modification.

Dietary advice: For safe and sustainable weight loss, focus on balanced nutrition, portion control, and consistent exercise. Quick fixes and viral hacks rarely deliver lasting results and may even cause digestive discomfort. If you’re serious about weight management, consult a registered dietitian or healthcare provider for evidence-based guidance tailored to your needs.

11. Raw Potato Slices for Eye Bags

One enduring TikTok remedy for puffy under-eye bags is the use of raw potato slices. The hack involves placing thin slices of potato directly beneath the eyes for several minutes, with users claiming almost instant reduction in puffiness and dark circles. The biological rationale is that potatoes have natural anti-inflammatory agents, as well as enzymes and vitamin C, which may help soothe skin and reduce swelling.

While the coolness of the potato can indeed temporarily constrict blood vessels and diminish puffiness, this effect is similar to that of a standard cold compress. According to the Cleveland Clinic, cold compresses—whether cucumber, potato, or ice pack—work by reducing fluid accumulation and inflammation, but the specific vegetable used matters little.

Safety: Raw potato slices are generally safe for short-term use, but always wash potatoes thoroughly and avoid placing them on broken or irritated skin. For chronic under-eye swelling, consult a dermatologist, as persistent puffiness can indicate underlying health issues or allergies that require professional attention.

12. Banana Peel Teeth Whitening

The TikTok trend of rubbing banana peels on teeth promises a brighter smile without chemicals. Advocates claim that the minerals in banana peel—such as potassium, magnesium, and manganese—are absorbed by the teeth, helping to lift stains and whiten enamel. After rubbing the inner side of the peel on teeth for a few minutes, users report a subtle whitening effect.

However, dental experts are skeptical. There is no scientific evidence that the minerals in banana peel can penetrate enamel or produce significant whitening. According to the American Dental Association, effective teeth whitening typically requires peroxide-based products, which are designed to break down stains at a molecular level. Banana peels may help remove superficial debris through gentle abrasion, but they cannot match the results of professional whitening treatments or even over-the-counter whitening toothpastes.

Oral care pointers: For noticeable and safe whitening, use ADA-approved products and maintain regular dental checkups. Always be wary of viral hacks that lack scientific backing—protecting your enamel is more important than chasing quick, unproven results.

13. Vicks VapoRub for Bigger Lips

A quirky beauty hack circulating on TikTok suggests applying Vicks VapoRub to the lips for a fuller, plumper appearance. The theory is that menthol, camphor, and eucalyptus oil in the rub cause mild irritation, increasing blood flow and temporarily swelling the lips. Users often share videos showing tingling sensations and a slight pout, likening the effect to that of expensive lip plumpers.

However, this method relies on irritation, not genuine volumizing. The swelling is a result of inflammation, which can lead to redness, dryness, and even allergic reactions. The Healthline warns that repeated use can cause more harm than benefit, especially for those with sensitive or chapped skin.

Comparison with cosmetic fillers: Unlike injectable fillers, which add volume safely when performed by professionals, Vicks offers only a fleeting and potentially risky effect. If you desire fuller lips, consult a licensed provider for safe, lasting options. Chasing trends with household products often leads to more irritation than enhancement.

14. Onion Water for Hair Growth

Onion water rinses have become a popular DIY solution on TikTok for those seeking to boost hair growth. The hack involves blending or juicing onions and applying the pungent liquid to the scalp, with claims that it stimulates hair follicles and encourages thicker, faster growth. The reasoning lies in onions’ high content of sulfur compounds, which are believed to support keratin production and improve blood circulation to hair roots.

Some small studies, such as one referenced by the National Institutes of Health, show potential benefits for patchy hair loss (alopecia areata), but the evidence is far from robust. Medicated treatments like minoxidil and prescription therapies remain the gold standard for clinically proven results and are much more thoroughly researched.

Allergy considerations: Onion water can trigger skin irritation, rashes, and allergic reactions, especially for those with sensitive or broken skin. Always perform a patch test before applying any new substance to your scalp. For persistent hair loss or scalp concerns, consult a dermatologist to explore safe, effective treatment options backed by science.

15. Ice Bath Challenges

TikTok’s “ice bath challenge” dares users to plunge into tubs filled with freezing water, often for several minutes, in pursuit of supposed health and mental benefits. Proponents claim that ice baths enhance circulation, speed muscle recovery, boost metabolism, and build mental resilience. Athletes have long used cold immersion for post-workout recovery, as the shock of cold water can constrict blood vessels, reduce inflammation, and temporarily numb soreness.

However, these benefits come with risks. The Johns Hopkins Medicine notes that sudden cold exposure can cause rapid heart rate, blood pressure spikes, and dangerous drops in core body temperature, especially for those with underlying heart or metabolic conditions. While brief, supervised ice baths may help well-conditioned athletes, unsupervised challenges can result in hypothermia, fainting, or cardiac events.

Cold exposure safety: Always consult a healthcare provider before attempting extreme cold therapy. Limit immersion time, avoid full-body submersion if inexperienced, and never attempt ice baths alone. Sensible use, rather than viral dares, is key to safe and beneficial cold exposure.

16. Scented Wax for Appetite Suppression

A peculiar TikTok trend involves inhaling scented wax—such as from candles or wax melts—to reduce appetite and curb cravings. The premise is that strong, pleasant aromas can stimulate olfactory pathways, which are closely linked to the brain’s hunger and satiety centers. Some users claim that certain scents, like vanilla or cinnamon, help distract them from snacking or overeating.

There is a scientific basis for the idea that smell influences appetite. According to research highlighted by the National Institutes of Health, food-related scents can increase cravings, while some non-food scents may diminish them by reducing the salience of hunger cues. However, the effect is usually modest and temporary, and inhaling wax directly or excessively can expose you to potentially harmful chemicals or irritants.

Managing hunger healthily: Sustainable appetite management relies on balanced meals, mindful eating, adequate hydration, and regular physical activity. Instead of following viral hacks, focus on proven strategies to support healthy metabolism and long-term weight control. If hunger feels overwhelming or unmanageable, consult a nutritionist or healthcare professional for guidance.

17. Cabbage Leaves for Breast Pain

A surprising TikTok remedy for breast pain, particularly engorgement related to breastfeeding, is the application of chilled cabbage leaves directly to the breasts. This hack has actually been around for decades, with many lactation consultants recommending it as a home comfort measure. The cooling sensation of cabbage leaves is soothing, while the leaves themselves contain phytochemicals that may have mild anti-inflammatory effects, helping to reduce swelling and discomfort.

Studies referenced by the National Institutes of Health suggest that cabbage leaves can be as effective as cold compresses for relieving breast engorgement and short-term pain. The leaves are typically washed, chilled, and placed over the breast for 20 minutes at a time. This method is generally considered safe for short-term use and does not interfere with breastfeeding.

Medical context: While cabbage leaves can offer temporary relief, persistent or severe breast pain should always be evaluated by a healthcare professional to rule out infection or other complications. For ongoing discomfort, lactation support and proper breast care remain essential.

18. Sun Gazing for Eye Health

The TikTok trend of “sun gazing”—deliberately staring at the sun, often at sunrise or sunset, to allegedly improve vision and boost mood—has alarmed eye health experts. Some users claim that short periods of direct sun exposure can “energize” the eyes or regulate circadian rhythms. However, this practice is extremely dangerous and can result in permanent retinal damage.

Direct sunlight contains powerful ultraviolet and infrared rays that can burn the retina, leading to a condition called solar retinopathy. The American Academy of Ophthalmology warns that even brief unprotected exposure can cause irreversible vision loss, blind spots, and distorted vision. In contrast, safe light therapy for mood or circadian health uses filtered, indirect light and never involves looking directly at the sun.

Eye protection advice: Never look directly at the sun, even during sunrise or sunset. Wear UV-blocking sunglasses outdoors and use appropriate safety glasses for solar events. When it comes to eye health, trust medically sound advice—not viral trends that can put your vision at risk.

19. Crystal Face Rollers for Detox

Crystal face rollers—typically made from jade or rose quartz—are promoted on TikTok as miracle tools for “detoxing” the skin, reducing puffiness, and sculpting facial features. The rolling action is said to boost lymphatic drainage, which can temporarily move excess fluid away from the face. Some users claim that regular use leads to clearer skin, fewer toxins, and a youthful glow.

While the gentle massage provided by face rollers can stimulate blood flow and help with short-term puffiness, there’s little scientific evidence that they remove toxins or fundamentally change skin health. According to the Harvard Health Blog, the benefits of crystal rollers are comparable to those of manual facial massage—both can be relaxing and mildly reduce swelling, but neither offers a true “detox.”

Realistic outcomes: Crystal face rollers can be a soothing addition to your skincare routine, but don’t expect dramatic results. For actual skin transformation, stick to evidence-based skincare products and practices. Enjoy the ritual if it feels good, but know its limits.

20. Cinnamon Water for Blood Sugar

On TikTok, drinking cinnamon water is often recommended as a natural way to stabilize blood sugar levels, especially for those concerned about diabetes or insulin resistance. The appeal lies in cinnamon’s active compounds, such as cinnamaldehyde, which have been studied for their potential effects on glucose metabolism and insulin sensitivity.

Some research, including findings discussed by the Mayo Clinic, suggests that cinnamon may have a modest effect on fasting blood sugar, particularly in people with type 2 diabetes. However, results are mixed and the effects are generally not strong enough to replace proven diabetes treatments or lifestyle interventions. The amount of cinnamon in most TikTok recipes is unlikely to make a significant clinical difference.

Moderation advice: Cinnamon water is generally safe in small amounts, but consuming large quantities can be harmful, especially due to compounds like coumarin. For real blood sugar management, rely on evidence-based dietary choices, medication when prescribed, and regular medical care. Always consult your healthcare provider before using supplements or “hacks” as part of your diabetes routine.

21. DIY Ear Candling

Ear candling, a trend that resurfaces regularly on TikTok, involves inserting a hollow, wax-coated fabric candle into the ear canal and lighting the outer end. Proponents claim the resulting suction draws out earwax and toxins, leading to improved hearing and ear health. Videos often show what appears to be extracted wax after burning the candle, fueling the illusion of effectiveness.

However, medical evidence strongly refutes these claims. The American Academy of Otolaryngology-Head and Neck Surgery warns that ear candling is not only ineffective, but also poses significant risks—including burns, ear canal obstructions, and even eardrum perforations. The “debris” seen after candling is usually melted candle wax, not removed earwax.

Safe ear care alternatives: Most people do not need to remove earwax, as the ear is self-cleaning. If you experience blockage or discomfort, use over-the-counter ear drops or seek professional medical assistance. Avoid inserting objects or candles into your ears—safe ear care always prioritizes evidence-based methods over viral fads.

22. Blackout Sleep Masks for Deep Sleep

Blackout sleep masks are a TikTok favorite for those seeking deeper, more restorative sleep. The concept is rooted in circadian rhythm science: exposure to even small amounts of light during sleep can disrupt the body’s natural production of melatonin, the hormone that signals sleepiness and helps regulate the sleep-wake cycle.

According to the Sleep Foundation, using a blackout mask can improve both sleep quality and duration, particularly for people who cannot fully control bedroom lighting—such as shift workers or city dwellers. While making changes to the sleeping environment (like blackout curtains or removing electronic devices) can also help, masks provide a portable, affordable solution for blocking light.

Use tips: Choose a comfortable, breathable mask that fits well without putting pressure on the eyes. Clean it regularly, and use it as part of a consistent bedtime routine. While blackout masks are safe and effective for most people, anyone with eye infections or certain skin conditions should consult a healthcare provider before use.

23. DIY Nose Lifting Clips

DIY nose lifting clips, which promise a reshaped or “lifted” nose without surgery, have captured TikTok’s imagination. These plastic devices are worn over the nose for minutes to hours daily, with claims they can mold cartilage and alter nose shape over time. Videos often show before-and-after shots, fueling hopes for a non-invasive alternative to rhinoplasty.

However, the biology of cartilage makes such transformations highly unlikely. Cartilage in the nose is flexible but not easily reshaped by external pressure, especially in adults where it has fully developed. According to the American Society of Plastic Surgeons, only surgical procedures can permanently modify nasal structure. Temporary indentation or redness may occur with clips, but any “results” quickly fade once the device is removed.

Expectations: While nose clips may give the sensation of doing something, they won’t deliver lasting changes. If you are considering altering your nose’s appearance, consult a board-certified plastic surgeon for safe, realistic options. Viral gadgets cannot replace medical expertise or the precision of professional cosmetic procedures.

24. Papaya Seed Cleanses

TikTok videos touting papaya seeds as a gut “cleanse” have surged in popularity, with claims that eating the peppery seeds can detoxify the digestive tract and eliminate parasites. Papaya seeds do contain certain compounds, such as carpaine and benzyl isothiocyanate, which have demonstrated anti-parasitic properties in laboratory settings. Some small studies, like one referenced by the National Institutes of Health, suggest possible benefits against intestinal parasites.

However, the digestive effects of eating papaya seeds can also include nausea, diarrhea, and abdominal cramping, particularly if consumed in large quantities. The seeds are not a proven substitute for medically prescribed anti-parasitic treatments, which are rigorously tested for safety and efficacy. Relying on papaya seeds in place of proper medication can delay effective treatment and lead to complications.

Safety: Papaya seeds are generally safe in small amounts for most people, but excessive consumption can be toxic and may affect fertility. Always consult a healthcare provider before trying any “cleanse” or remedy, especially for suspected parasites or chronic digestive issues.

25. Salt Water Flushes for Detox

Salt water flushes have gone viral on TikTok as a supposed way to “detox” the digestive system and induce rapid bowel movements. The method involves drinking a mixture of warm water and a large amount of salt—often sea salt—on an empty stomach. Users report experiencing quick, forceful trips to the bathroom, claiming it cleanses the colon and removes toxins.

However, this practice is not without significant risks. Consuming salt water disrupts the body’s natural electrolyte balance and can lead to dehydration, nausea, vomiting, and even dangerous complications like sodium toxicity or kidney damage. Medical colon cleanses, used before certain procedures like colonoscopy, rely on carefully formulated solutions and are administered under medical supervision. The Johns Hopkins Medicine warns against unregulated home detoxes, which can do more harm than good.

Hydration tips: For a healthy digestive system, drink plenty of water, eat fiber-rich foods, and exercise regularly. Avoid extreme or unproven “flushes”—your body is naturally equipped to detoxify itself when supported by balanced hydration and nutrition.

26. Toothpaste on Pimples

The idea of dabbing toothpaste on pimples as a quick fix for breakouts has been a staple of home remedies for years, recently revived on TikTok. Toothpaste is thought to dry out pimples due to its ingredients, including baking soda, hydrogen peroxide, and menthol. However, these substances are not designed for use on facial skin and can cause more harm than good.

Dermatologists caution that the chemical irritants in toothpaste can lead to redness, peeling, burning, and even chemical burns, especially on sensitive or inflamed skin. According to the American Academy of Dermatology, over-the-counter acne treatments containing benzoyl peroxide or salicylic acid are safer and more effective for targeting pimples.

Skin safety advice: Instead of reaching for toothpaste, use products formulated for acne-prone skin and avoid picking or squeezing pimples. If breakouts are persistent or severe, consult a dermatologist for tailored advice. Viral hacks may appear harmless, but your skin deserves evidence-based care.

27. Belly Button Oil Application

A TikTok trend that has gained traction is the practice of putting oils—such as mustard, coconut, or castor oil—directly into the belly button, with claims it can improve skin, digestion, or even hormonal balance. This hack is rooted in the ancient belief that the navel is an “absorption center” for the body, supposedly delivering nutrients and healing compounds throughout the system.

However, the idea that oil applied to the navel can be absorbed and provide widespread health benefits is largely a myth. The belly button is a scar with no direct internal connection to organs or blood vessels. While oil may hydrate the local skin and possibly soothe mild irritation, it does not act as a delivery system for the rest of the body. According to Healthline, topical oils are most effective when massaged onto areas needing moisture or care, such as dry elbows or cuticles.

Evidence: There is no scientific research supporting extraordinary health benefits from belly button oiling. For real improvements in skin or digestion, focus on proven topical or dietary interventions, and approach viral “navel hacks” with skepticism.

28. Black Coffee Before Exams

Drinking black coffee before exams is a popular TikTok study hack, promoted for its supposed ability to boost memory, sharpen focus, and enhance alertness. The science behind this trend is rooted in caffeine’s action on the nervous system: caffeine blocks adenosine receptors in the brain, reducing fatigue and temporarily improving concentration and reaction time.

Research, such as reviews by the National Institutes of Health, supports moderate caffeine intake for increased alertness and attention. However, high doses can lead to jitteriness, anxiety, increased heart rate, and poor sleep, all of which can undermine exam performance. Caffeine does not directly improve memory retention or learning—its benefits are mainly in helping you feel more awake in the short term.

Effective study habits: Combine strategic caffeine use with solid study techniques: space out your learning, practice active recall, and get adequate sleep. Don’t rely on coffee alone to carry you through exams—a balanced approach is key to academic success and long-term brain health.

29. DIY Alkaline Water

The creation of DIY alkaline water—by adding baking soda, lemon, or other ingredients to regular water—has gained popularity on TikTok, with claims that it balances the body’s pH, boosts energy, and prevents disease. The idea is that alkaline water (with a higher pH than standard tap water) can neutralize acidity in the body and promote better health.

However, human blood pH is tightly regulated by the kidneys and lungs, regardless of what you drink or eat. Scientific evidence does not support the notion that alkaline water significantly affects systemic pH or provides major health benefits. According to the Mayo Clinic, there is no robust research showing that alkaline water protects against disease or improves hydration compared to plain water.

Hydration recommendations: The best way to stay healthy is to drink enough water—plain or mineral—throughout the day. DIY “alkaline” recipes offer no clear advantage and may even upset stomach balance if overused. Trust your body’s own sophisticated systems, and hydrate sensibly.

30. Ice Cubes for Jawline Definition

A TikTok beauty hack suggests that rubbing ice cubes along the jawline can create a sharper, more defined facial contour. The cooling effect is thought to reduce swelling, tighten the skin temporarily, and highlight the jawline, giving the illusion of a more sculpted face. Many users post before-and-after videos, attributing visible changes to this cold therapy.

While applying ice can decrease puffiness by constricting blood vessels and reducing inflammation, the effects are temporary and mostly superficial. According to dermatologists interviewed by Health.com, icing may offer mild, short-term benefits for swelling or redness but does not actually alter bone structure or melt facial fat.

Comparison with facial exercises: Facial exercises may help tone underlying muscles, but neither ice nor exercise can drastically change your jawline’s shape. Realistic results: For lasting definition, consider healthy weight management and, if desired, consult a cosmetic professional. Viral beauty tricks might provide a fleeting boost, but true facial structure is determined by genetics and overall health.

31. Baking Soda Masks for Acne

Baking soda masks are another TikTok-fueled remedy touted for quick acne relief. The logic is that baking soda’s mild abrasiveness and alkaline pH can exfoliate dead skin and neutralize excess oil, supposedly clearing breakouts. Users often mix baking soda with water or lemon juice to form a paste, applying it as a mask for several minutes.

However, dermatologists strongly caution against this practice. Baking soda can disrupt the skin’s natural protective barrier and alter its normal acidic pH, making it more prone to dryness, irritation, and even worsening of acne. According to the American Academy of Dermatology, harsh DIY masks can strip the skin and lead to inflammation, ultimately causing more harm than good.

Safe alternatives: Stick to gentle, evidence-based treatments such as cleansers containing salicylic acid or benzoyl peroxide, and moisturize with non-comedogenic products. If your acne is persistent or severe, consult a dermatologist for tailored therapies. When it comes to skincare, less is often more, and professional guidance always beats viral improvisation.

32. Mustard Plaster for Chest Colds

Mustard plasters—pastes made from powdered mustard seed, flour, and water, spread on cloth and applied to the chest—have made a TikTok comeback as a folk remedy for chest colds and congestion. The practice dates back centuries, rooted in the belief that mustard’s warming sensation can ease coughs, stimulate circulation, and break up mucus.

When placed on the skin, mustard plasters create a strong heating effect by irritating the skin and increasing local blood flow. This may provide a temporary feeling of relief, but the benefits are mostly anecdotal and not supported by modern clinical research. According to Mount Sinai, mustard plasters can cause burns, blisters, or severe skin irritation—especially if left on too long or applied to sensitive skin.

Safety warnings: If you try a mustard plaster, always use a cloth barrier and check your skin frequently. Discontinue use immediately if you feel burning or discomfort. Seek medical care for persistent coughs or chest pain, and rely on evidence-based remedies for respiratory health instead of unproven, potentially hazardous home treatments.

33. TikTok ‘Internal Shower’ Chia Drink

The “internal shower” drink—made by mixing chia seeds with water and sometimes lemon juice—has gained massive attention on TikTok as a supposed fix for digestive sluggishness and constipation. Chia seeds are rich in soluble fiber, which absorbs water and forms a gel-like substance that can help bulk up stool and promote regular bowel movements.

According to the Healthline, fiber from chia seeds supports gut health and can relieve mild constipation, but results are not immediate and depend on overall diet and hydration. Unlike stimulant laxatives, which force the bowel to contract, fiber works more gently and is less likely to cause cramping or dependence. However, consuming chia seeds dry or without enough water can lead to choking or digestive discomfort.

Usage guidelines: Always soak chia seeds thoroughly before drinking and increase fiber intake gradually to avoid bloating or gas. For persistent digestive issues, consult a healthcare provider. While chia drinks can be a healthy addition to your diet, they are not a cure-all—maintain a balanced diet and drink plenty of fluids for optimal gut health.

34. Aspirin Masks for Glowing Skin

Aspirin masks—made by crushing aspirin tablets and mixing them with water or honey—are promoted on TikTok as a way to achieve glowing, clear skin. Aspirin contains acetylsalicylic acid, a compound related to salicylic acid, which is known for its anti-inflammatory and exfoliating properties. The idea is that applying aspirin topically can reduce redness, calm inflammation, and unclog pores.

While there is some logic behind this, dermatologists generally prefer products specifically formulated with salicylic acid for acne and exfoliation. Over-the-counter skin care products contain precise concentrations and are tested for safety and efficacy, while DIY aspirin masks may have unpredictable results or cause irritation. According to the American Academy of Dermatology, aspirin masks are not recommended due to potential skin reactions and the risk of allergy, particularly for those sensitive to nonsteroidal anti-inflammatory drugs (NSAIDs).

Allergy risks: Aspirin can provoke allergic reactions and should be avoided by anyone with an aspirin allergy or asthma. For glowing skin, stick to proven, dermatologist-recommended products and consult with a professional for persistent skin issues.

35. ‘Nature’s Cereal’ Breakfast

The “Nature’s Cereal” trend on TikTok features a bowl of fresh fruit—typically berries, pomegranate seeds, and sometimes kiwi—topped with coconut water instead of milk. This vibrant breakfast has been celebrated for its hydrating, nutrient-rich profile and its ability to offer a refreshing start to the day. Fans claim it boosts energy, supports digestion, and even clears skin.

Nutritionally, Nature’s Cereal provides antioxidants, vitamins, minerals, and fiber from the fruit, while coconut water adds electrolytes like potassium and magnesium. Compared to many standard cereals, which may be high in added sugars and processed grains, this fruit-based breakfast is a lower-calorie, whole-food alternative. According to EatRight.org, building breakfast around whole fruits can support overall wellness.

Balanced diet tips: While Nature’s Cereal is a healthy option, it lacks protein and healthy fats. For a balanced meal, consider adding yogurt, nuts, or seeds. Variety and moderation are key to meeting your daily nutritional needs—don’t be afraid to adapt viral recipes for a more complete breakfast.

36. Vaseline Eyelash Growth

The idea that applying Vaseline (petroleum jelly) to eyelashes will make them grow longer or thicker has gained traction on TikTok, with users posting before-and-after videos claiming dramatic lash improvements. Vaseline is an occlusive moisturizer that can help soften and protect hair, preventing breakage and making lashes appear glossier and healthier.

However, there is no scientific evidence that Vaseline stimulates actual eyelash growth. Unlike prescription lash serums containing bimatoprost or over-the-counter serums with peptides and botanical extracts, petroleum jelly does not affect the growth cycle of hair follicles. According to Healthline, Vaseline may improve the appearance of lashes by conditioning them, but results are temporary and purely cosmetic.

Eye safety: When using Vaseline near the eyes, apply sparingly and avoid getting it into the eyes, as it can cause irritation or blurred vision. For those seeking true lash growth, consult a dermatologist or ophthalmologist for medically approved solutions. Prioritize eye safety and be skeptical of viral beauty shortcuts.

37. Activated Charcoal for Hangovers

Some TikTok users tout activated charcoal as a hangover cure, suggesting that taking charcoal capsules after drinking alcohol will “soak up toxins” and prevent or mitigate hangover symptoms. Activated charcoal works by adsorption—it binds to certain substances in the gut, preventing their absorption into the bloodstream. This property makes it useful in emergency medicine for specific types of poisoning or drug overdoses.

However, activated charcoal is not effective for alcohol or most hangover-causing compounds. According to the National Capital Poison Center, charcoal does not bind well to ethanol (the main component of alcoholic drinks) and is not recommended for hangover prevention or treatment. Medical detoxification for alcohol poisoning involves supportive care, not charcoal capsules.

Effectiveness: There is no scientific basis for using activated charcoal as a hangover remedy. The best ways to prevent hangovers are to drink alcohol in moderation, stay hydrated, and eat before drinking. If you experience severe symptoms after alcohol use, seek medical attention rather than relying on viral “cures.”

38. Egg White Face Masks

Egg white face masks are a classic DIY skincare remedy, now trending on TikTok for their supposed skin-tightening and pore-minimizing effects. The rationale is that as egg whites dry on the skin, they create a temporary tightening sensation, and the proteins may lightly nourish the surface. Some users claim their skin looks smoother and more lifted after application.

While egg whites contain proteins that can form a thin, temporary film over the skin, the effects are fleeting and largely superficial. Commercial masks often use similar film-forming agents but are formulated for safety and efficacy, reducing the risk of irritation. According to Healthline, there is little evidence that egg white masks provide lasting benefits or outshine professional skincare products.

Salmonella risk: Using raw eggs on the face carries a risk of bacterial contamination, especially if the egg comes into contact with the mouth, eyes, or broken skin. For effective and safe skin tightening, opt for dermatologist-approved products and avoid raw eggs in your beauty routine.

39. Potato Juice for Sunburn

Potato juice is a TikTok remedy for soothing sunburned skin, with users grating raw potato or applying its juice directly to inflamed areas. The starchy liquid is said to provide a cooling effect and help reduce redness and discomfort. Potatoes contain vitamins, antioxidants, and natural anti-inflammatory compounds, which may offer mild relief when applied topically.

While the immediate cooling and moisturizing sensation of potato juice may calm the skin, there is little evidence that it outperforms traditional remedies like aloe vera. Aloe vera gel, as noted by the American Academy of Dermatology, is clinically proven to reduce sunburn-related pain and inflammation. It is formulated for safe, effective skincare and is less likely to cause irritation or allergic reactions.

Sunburn care tips: For sunburn, use cold compresses, gentle moisturizers, and over-the-counter anti-inflammatories if necessary. Avoid further sun exposure and keep the skin hydrated. When trying home remedies, always patch-test first—and for severe or blistering burns, seek medical attention.

40. Aloe Vera Juice for Digestion

Aloe vera juice has become a popular TikTok health trend, touted for its ability to soothe the digestive tract, relieve heartburn, and promote regularity. The juice is rich in compounds like aloin, polysaccharides, and antioxidants, which are believed to reduce inflammation and support gut health. Many users claim that a daily shot of aloe vera juice helps with bloating, constipation, and even irritable bowel syndrome (IBS).

Scientific evidence on aloe’s digestive benefits is mixed. While some studies suggest aloe vera may have a mild laxative effect and offer relief for certain digestive complaints, most findings are based on short-term use and involve specific, decolorized preparations. According to the Mayo Clinic, excessive consumption can cause diarrhea, cramping, and electrolyte imbalances, especially if the juice contains aloin.

Dosage caution: If you want to try aloe vera juice, choose products labeled as “purified” or “decolorized” and stick to recommended serving sizes. Always consult a healthcare professional before adding new supplements to your routine, particularly if you have underlying digestive or kidney conditions.

41. Hot Pepper Patches for Pain Relief

Hot pepper patches, inspired by TikTok trends and traditional remedies, are used for localized pain relief—thanks to capsaicin, the compound that gives chili peppers their heat. Capsaicin works by overstimulating pain receptors in the skin, eventually reducing their ability to transmit pain signals to the brain. This mechanism is why capsaicin creams and patches are often recommended for arthritis, nerve pain, or sore muscles.

Prescription-strength capsaicin patches, such as those used in clinics for neuropathic pain, are carefully formulated and supervised by healthcare professionals. Over-the-counter products can provide mild relief, but DIY patches using raw hot peppers or homemade mixtures pose a significant risk of skin burns, irritation, and allergic reactions. According to the Mayo Clinic, improper use of capsaicin can cause intense burning, redness, and even blistering.

Irritation risk: Always follow the instructions for any topical pain product and do not apply to broken or sensitive skin. If you experience severe irritation, wash the area thoroughly and seek medical advice. For persistent pain, consult a healthcare provider for safe and effective treatment options.

42. DIY Cough Syrup with Onion and Honey

DIY cough syrups made from onions and honey have gained popularity on TikTok as a natural remedy for soothing sore throats and calming coughs. The mixture is prepared by slicing onions, covering them with honey, and allowing the combination to sit until a syrup forms. Both ingredients possess antimicrobial and soothing properties—honey, in particular, has been shown to coat the throat and reduce cough frequency, while onions contain compounds with mild antibacterial effects.

While homemade syrups like this can offer comfort for mild coughs, their effects are generally modest compared to over-the-counter medicines containing ingredients like dextromethorphan or guaifenesin. According to Mayo Clinic, honey may be as effective as some commercial cough remedies for children over one year old, but onions’ benefits are less well established.

Use guidelines: Never give honey to children under one year due to the risk of botulism. Use onion and honey syrup as a supplementary comfort measure, not a replacement for medical treatment. For persistent or severe coughs, consult a healthcare provider to rule out underlying conditions.

43. Tanning with Baby Oil

A dangerous TikTok trend encourages users to apply baby oil to their skin while tanning, promising a quicker, deeper bronze. Baby oil intensifies the sun’s rays by creating a reflective layer, causing the skin to absorb more ultraviolet (UV) radiation in less time. While the immediate result may be a rapid tan, the long-term consequences are far more serious.

Dermatologists warn that using baby oil for tanning dramatically increases the risk of sunburn, premature aging, and most importantly, skin cancer. According to the Skin Cancer Foundation, there is no safe way to tan, and oils that lack sun protection factor (SPF) provide zero defense against harmful UV rays. In contrast, broad-spectrum sunscreen shields the skin from both UVA and UVB radiation, reducing the risk of cellular damage and disease.

Sun safety: The best way to protect your skin is to use SPF 30 or higher, seek shade during peak hours, and wear protective clothing. Embrace your natural skin tone and avoid risky tanning hacks that compromise your long-term health for short-term aesthetics.

44. Apple Cider Vinegar Shots for Weight Loss

Drinking undiluted apple cider vinegar (ACV) shots has become a popular weight loss hack on TikTok, with claims that it “burns fat,” boosts metabolism, and suppresses appetite. ACV contains acetic acid, which may have a modest effect on insulin sensitivity and blood sugar regulation. Some small studies suggest it might help with feelings of fullness, but there is no solid evidence that ACV alone leads to significant, sustainable weight loss.

Compared to balanced dietary changes—such as reducing processed foods, increasing fiber, and controlling portions—ACV offers little in the way of lasting results. The Cleveland Clinic warns that undiluted ACV can erode tooth enamel, irritate the esophagus, and cause digestive discomfort.

Dental warnings: If you choose to consume apple cider vinegar, always dilute it in water and drink through a straw to minimize contact with teeth. For safe and effective weight loss, focus on proven lifestyle strategies and consult with a healthcare professional before adding any new supplement to your routine.

45. ‘Sniffing’ Essential Oils for Immunity

The TikTok trend of “sniffing” essential oils—such as eucalyptus, tea tree, or lemon oil—to boost immunity has gained widespread attention. Proponents claim that inhaling these potent plant extracts can bolster the immune system by stimulating olfactory pathways and reducing exposure to airborne pathogens. The nose and immune system are indeed linked, as the nasal passages filter and react to environmental substances.

However, scientific evidence supporting the idea that inhaling essential oils directly increases immune function is limited. According to the National Center for Complementary and Integrative Health (NCCIH), while aromatherapy may help with relaxation and mood, claims about preventing illness or enhancing immunity are not substantiated by robust clinical trials. Essential oils are not substitutes for vaccination, proper hygiene, or evidence-based medical care.

Safe aromatherapy practice: Use essential oils in a diffuser or diluted with a carrier oil, and avoid direct, prolonged inhalation. Some oils can cause allergic reactions or respiratory irritation. Always follow manufacturer guidelines and consult a healthcare provider if you have asthma or other chronic respiratory conditions.

46. DIY Freckle Tattoos with Sewing Needles

A particularly alarming TikTok trend is the attempt to create DIY freckle tattoos at home using sewing needles and ink—or sometimes even household dyes. This method involves puncturing the skin with a needle dipped in pigment to mimic natural freckles. While the viral appeal is understandable, the risks far outweigh any aesthetic reward.

Home tattooing with unsterilized equipment introduces a high risk of bacterial infection, scarring, allergic reactions, and the transmission of bloodborne diseases. The American Academy of Dermatology strongly warns against DIY tattooing, emphasizing that professional tattoo artists follow strict sterilization protocols and use safe, approved pigments. Even with professional procedures, complications can occur, but the risks are exponentially greater at home.

Wound care: If you attempt any form of skin puncture and notice redness, swelling, pus, or fever, seek medical attention immediately. For those interested in semi-permanent freckles, consult a licensed aesthetician or cosmetic tattoo artist. Never compromise your health and safety for a fleeting trend—leave tattoos to the professionals.

47. TikTok ‘What I Eat in a Day’ Diets

The “What I Eat in a Day” videos on TikTok have become a major source of diet inspiration, especially among teens and young adults. These influencers showcase visually appealing meals and snacks, often touting extreme restriction, “clean eating,” or trendy superfoods as the secret to their physique or wellness. While these videos can provide recipe ideas, they rarely offer a nutritionally balanced or sustainable blueprint for viewers.

Nutritional adequacy is highly individual—what works for one person may not meet another’s needs, especially given differences in age, metabolism, activity level, and health conditions. According to EatRight.org, following generic or influencer-driven diets can lead to nutrient deficiencies, disordered eating, and unhealthy body image pressures.

Critical viewing advice: Approach viral diet content with skepticism and avoid copying someone else’s meal plan without considering your own health needs. If you want to change your diet, consult a registered dietitian or healthcare provider for a personalized, evidence-based plan that supports your goals and well-being.

48. DIY Blackhead Removal with Glue

A risky TikTok hack involves applying school glue as a peel-off mask to extract blackheads and clear pores. Inspired by the adhesive nature of commercial pore strips, some users claim that glue dries into a flexible film that can “lift out” blackheads when peeled away. While this may seem like an easy shortcut, the risks far outweigh any potential benefit.

School glue is not designed for use on the skin and contains chemicals that can cause irritation, allergic reactions, or even chemical burns. According to the American Academy of Dermatology, commercial blackhead strips are tested for safety and skin compatibility—while DIY glue masks are not. The harsh removal process can also damage the skin barrier, increasing sensitivity, redness, or even small wounds.

Skin protection tips: For blackhead removal, use products formulated for facial care, such as gentle exfoliants or salicylic acid-based cleansers. Avoid using household items on your skin, and always patch-test new products before widespread use. Prioritize safety and consult a dermatologist for stubborn or persistent blackheads.

49. Tooth Gem Application at Home

Applying tooth gems at home is a growing trend on TikTok, with users gluing rhinestones or decorative gems directly onto their teeth for a flashy, temporary look. While professional dental offices offer safe, reversible tooth gemstone bonding, DIY methods often involve household adhesives or nail glue, which are not intended for use in the mouth.

These unregulated adhesives can damage enamel, irritate gum tissue, and even cause the gem to dislodge and become a choking hazard. According to the American Dental Association, at-home tooth gem application can lead to cavities, infection, and irreversible harm to teeth. Dental professionals use specialized bonding agents and ensure the tooth’s surface is properly prepared to minimize risk.

Oral health advice: If you want a tooth gem, always see a licensed dental professional and avoid home kits or DIY attempts. Maintain good oral hygiene and monitor the area for any signs of discomfort or damage. Prioritize your dental health over fleeting trends—your teeth are meant to last a lifetime.

50. TikTok ‘Detox Foot Pads’

Detox foot pads, which claim to draw toxins out of the body overnight through the soles of your feet, have gone viral on TikTok. These adhesive pads often contain ingredients like bamboo vinegar, tourmaline, and herbs, and users are encouraged to marvel at the darkened, “toxin-laden” residue left behind in the morning. The supposed mechanism is that the pads stimulate sweat glands and absorb harmful substances directly from the body.

Despite the dramatic visual results, scientific evidence does not support any detoxifying effect. Studies, including investigations reviewed by Healthline, have found that the color change is due to a reaction with sweat and air, not actual toxins being removed. The human body naturally detoxifies via the liver, kidneys, and skin—not through superficial foot applications.

How to spot pseudoscience: Be wary of products that promise quick, dramatic results with little credible evidence. Look for peer-reviewed research, beware of anecdotal testimonials, and consult healthcare professionals for true detoxification or wellness needs. Your feet—and your health—deserve better than viral pseudoscience.

Conclusion

TikTok’s viral health hacks are captivating, but their popularity underscores a pressing need for vigilance and discernment. As we’ve seen, what trends online can range from harmless to seriously hazardous—sometimes with lasting consequences. Misinformation spreads rapidly on social platforms, making it vital to critically assess every claim, fact-check with authoritative sources, and consult qualified health professionals before trying new remedies. Reputable resources such as the Centers for Disease Control and Prevention (CDC) and the Mayo Clinic should be your go-to guides. Prioritize your well-being by making informed decisions, not just following the latest fad. Your health deserves careful, evidence-based care—on and off social media.
