Psoriasis is an immune condition, which causes symptoms on the skin and sometimes the joints. When a person has psoriasis, their skin replacement process speeds up, taking just a few days to replace skin cells that usually take 21-28 days. This abundance of skin cells builds up to form raised ¡®plaques¡¯ on the skin, which can also be flaky, scaly, red on caucasian skin, darker patches on darker skin tones, and itchy. Psoriasis can occur on any area of the body, including the scalp, hands, feet and genitals, although different types tend to occur on different areas.
