What is Psoriasis?
Psoriasis is a common chronic skin disease that generally appears as patches of raised red skin covered by a flaky white buildup. More than 4.5 million adults in the United States have some type of psoriasis. In general, the condition is frequently found on the knees, elbows, scalp, hands, feet or lower back. Certain types of psoriasis may also have a bumpy appearance and cause intense itching and burning. The condition comes in different forms and varying levels of severity and is among the many conditions board-certified dermatologists treat.
