Phototherapy is a form of light treatment which involves exposing diseased skin to ultraviolet light via a phototherapy booth. Phototherapy has known benefits for the treatment of psoriasis, eczema and other inflammatory or itchy conditions.
This is helpful in treating psoriasis, which causes skin cells to grow too rapidly.
Treatment involves exposing the skin to an artificial UVB light source for a set length of time on a regular schedule. UV psoriasis light treatment, also known as UV Phototherapy, exposes the T-cells, causing them to die. In this way, the light therapy reduces inflammation, and slows the rate of skin cell production.
