Psoriasis is an autoimmune disease that results in red, scaly, itchy patches of skin that often recur even after successful treatment.

The condition tends to show up from the ages of 20 to 30 and then again, sometimes for the first time, from ages 50 to 60. Psoriasis is one of the best understood skin diseases, and a number of proven therapies are available. 

Yale Medicine has leading experts in this condition who take on the most challenging cases, using precision and creativity to help people recover.
