How does light therapy treat psoriasis?

ANSWER

Ultraviolet light targeted at problem areas can help control psoriasis outbreaks, but it should be done only under a doctor's care.

Common side effects include minor burns and a higher risk of skin cancer. It also can make you more sensitive to sunlight. With photochemotherapy, which includes a drug that makes the ultraviolet light work better, short-term side effects also include nausea, itching, and red skin.
