About Psoriasis

Psoriasis is a chronic, autoimmune disease that appears on the skin. It occurs when the immune system sends out faulty signals that speed up the growth cycle of skin cells. Psoriasis is not contagious.

Plaque psoriasis is the most common form of psoriasis, and appears as raised, red patches covered with a silvery white buildup of dead skin cells. Psoriasis is associated with other serious health conditions, such as diabetes, heart disease, and depression. Psoriasis is the most common autoimmune disease in the U.S. As many as 7.5 million Americans have psoriasis.

Psoriasis can show up anywhere—on the eyelids, ears, mouth and lips, skin folds, hands and feet, and nails. The burden of psoriasis extends well beyond physical appearances and can impact activities of daily living. To learn more about Psoriasis, click here:
