Q: Will the sun help my psoriasis?

A: Those who have psoriasis find that the sun helps to improve their skin’s appearance. For some the change is dramatic, with red scaly patches almost disappearing altogether during summer months in a warm climate. Because ultraviolet light is so effective for so many with psoriasis, it is often used in various artificial forms by doctors. Ultraviolet treatment with a sun lamp is often given in hospitals for plaque psoriasis (the most common type) and guttate psoriasis. In severe cases of psoriasis, dermatologists may use a treatment known as PUVA – P for psoralens plus UVA. Psoralens are chemicals found in certain plants which make the skin respond to UVA, the least dangerous form of UV light.
