Psoriasis affects the life cycle of skin cells. It causes cells to build up rapidly on the surface of the skin, forming thick silvery scales and itchy, dry, red patches that are sometimes painful.

Psoriasis commonly affects the skin of the elbows, knees, and scalp. Psoriasis has many different appearances. It may be small flattened bumps, large thick plaques of raised skin, red patches, and pink mildly dry skin to big flakes of dry skin that flake off.
