Psoriasis is a chronic autoimmune skin condition that causes cells to build up rapidly on the surface of the skin, forming thick, silvery scales and itchy, dry, and red patches. Psoriasis affects about 2-3% of the global population. This condition can occur on any part of the body, including the scalp, face, hands, and feet. The exact cause of psoriasis is unknown, but it is believed to be a combination of genetic and environmental factors that trigger an overactive immune response, leading to inflammation and an excessive growth of skin cells. While there is no cure for psoriasis, there are various treatments available to manage symptoms. Let’s take a look at some of the most effective treatments for psoriasis.
Narrowband Ultraviolet B Therapy
Narrowband ultraviolet B (NB-UVB) therapy works by exposing the skin to a specific wavelength of ultraviolet light. This ultraviolet light slows down the growth of skin cells and reduces inflammation. During an NB-UVB session, a person stands in a light booth or sits in front of a light panel while their skin is exposed to UVB light. The skin is exposed for a short period of time, gradually increasing in duration over several weeks. The treatment is typically administered two to three times a week, and significant improvement can be seen after several weeks of treatment. NB-UVB therapy is a safe and effective treatment option for psoriasis and can be used alone or in combination with other therapies, such as topical medications or systemic treatments.
