What Is Psoriasis?

Psoriasis is a skin disease that causes itchy or sore patches of thick, red skin with silvery scales. A problem with your immune system causes psoriasis. In a process called cell turnover, skin cells that grow deep in your skin rise to the surface. Normally, this takes a month. In psoriasis, it happens in just days because your cells rise too fast.

Psoriasis can last a long time (even a lifetime). It can occur at any age, but it usually occurs in adults. It sometimes runs in families.
