Psoriasis is a common skin disorder that produces thick, pink to red, itchy patches of skin covered with silvery scales.
It speeds up the life cycle of skin cells. It causes cells to build up rapidly on the surface of the skin
The rash usually occurs on the scalp, elbows, knees and lower back. And in the same place on both sides of the body. It can also occur in fingernails.
Psoriasis has no cure, but treatment greatly improves it, even in severe cases.
Common treatments include steroid creams, vitamin D derivatives. And topical retinoids – these may also be used with ultraviolet light therapy for severe cases.
For severe disease, there are a number of effective therapies taken in pill form or by injection.
