Psoriasis is a chronic, autoimmune disease that appears on the skin. It occurs when the immune system sends out faulty signals that speed up the growth cycle of skin cells. Psoriasis is not contagious.

Psoriasis is the most common autoimmune disease in the U.S. As many as 7.5 million Americans have psoriasis. Psoriasis has been linked to other serious health conditions, such as cardiovascular disease and depression. About 30 percent of people with psoriasis develop psoriatic arthritis.
