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.
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.
