UVB Phototherapy

UVB is present in natural sunlight and is an effective treatment for psoriasis. UVB penetrates the skin and slows the growth of affected skin cells. Treatment using UVB can include UVB phototherapy, excimer laser, or in-office or home UVB phototherapy.

Treating psoriasis with home UVB phototherapy can be an economical and convenient choice. Like phototherapy in a health care provider`s office or clinic, it requires a consistent treatment schedule.
