Light Therapy: A Brighter Future with Psoriasis?
Many people with psoriasis use light therapy to help clear up hard-to-treat patches of skin, as well as larger areas of the body affected by the condition. Light therapy, or phototherapy, is an option when topical treatments alone don’t work. People like it because it can clear up psoriasis for as long as six to 12 months.
The standard light therapy devices use ultraviolet B (UVB) rays, which are also found in natural sunlight. When exposed to the skin, UVB rays slow the abnormally rapid turnover of skin cells that constitutes psoriasis.
