UV Light Treatment for Psoriasis
Millions of people suffer from psoriasis, a condition that causes thick patches of skin, covered with silvery scales. According to the American Osteopathic College of Dermatology, UV light treatment is an effective treatment for psoriasis because it stimulates the production of vitamin D and suppresses the immune system cells in the skin. With the aid of a doctor, light treatment can be done at home or in an office.

UVB
-
Patients benefit from consistent exposure to UVB light because it penetrates the skin and slows down the growth of cells. The treatment should be done under a doctor's guidance in an office, psoriasis day-care center or clinic, or with a phototherapy unit at home.
UVB Side Effects
-
The appearance of psoriasis can worsen while undergoing UV light treatment, before it improves. Exposure to UVB light can cause your skin to get red and itchy. If it continues, lower the amount of exposure.

UVA
-
Ultraviolet light A or UVA can be used in conjunction with a medication called psoralen to treat psoriasis. Usually 25 treatments within 2 to 3 months are needed to clear psoriasis; 30 to 40 per year will keep it under control.
UVA Side Effects
-
UVA treatment can cause nausea, redness of the skin and itching. If this occurs, drink ginger ale or milk to reduce nausea and apply ointments with capsaicin to help your skin.
Phototherapy
-
People with psoriasis typically need between two and five phototherapy treatments each week with a special lamp or laser that emits light. There are two highly effective types but each have potential drawbacks: broadband phototherapy does not reach the scalp and areas where there are skin folds whereas narrowband phototherapy may cause severe burning.
Types
-
Your doctor will teach you how to use an at-home phototherapy unit. It requires a consistent schedule and regular check-ups. Some insurance companies will cover the cost of equipment.
