Treatment options for psoriasis can control it

Psoriasis is a chronic autoimmune skin disease that affects more than 7 million people in the U.S. and approximately 125 million people worldwide. There are five major types of psoriasis, with varying degrees of severity. The inflammatory condition occurs when overactive T-cells attack healthy skin cells, causing them to reproduce at an abnormally rapid rate, which results in irritation, scaly patches and thick, flaky lesions on the skin and scalp. Psoriasis also can affect joints, and up to 30 percent of people with psoriasis develop psoriatic arthritis as a result.
