Psoriasis is considered an autoimmune disease that causes inflammation and makes skin grow at an accelerated rate. Psoriasis flare-ups are most likely caused by a combination of genetics and environmental triggers such as stress, infection, cold weather, and diet.

Psoriasis symptoms vary widely, depending on the type of psoriasis and where it appears on the body. The disease often cycles between flare-ups in which psoriasis symptoms are most pronounced, and periods of remission that can last for several months. In psoriasis severe cases, smaller patches of inflamed, scaly skin grow together or overlap to cover large areas of the body.

• Red patches of skin covered with thick white scales
