Psoriasis is a skin disorder that causes skin cells to multiply up to 10 times faster than normal. This makes the skin build up into bumpy red patches covered with white scales. They can grow anywhere, but most appear on the scalp, elbows, knees, and lower back. Psoriasis can’t be passed from person to person. It does sometimes happen in members of the same family.
Despite the fact that psoriasis is incurable, it responds well to many topical and systemic treatments. Even people with severe psoriasis can get relief during flare-ups in most cases.
