Phototherapy is the use of ultraviolet (UV) light to slow the rapid growth of new skin cells.
Who gets it?
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.
