Psoriasis is an immune-mediated disease that causes raised, scaly patches on the skin due to systemic inflammation [1]. Symptoms of psoriasis vary and can include thick areas of discolored skin with silvery scales, itchy or sore patches of thick red skin, and bumps or rashes [4][5][6][8][9]. Commonly affected areas are the elbows, knees, scalp, lower back, face, palms and soles of feet [2], but it can affect any part of the body. Over 8 million people in the U.S. have psoriasis and nearly a third will develop psoriatic arthritis [3]. Treatment options for psoriasis include topical medications such as corticosteroids or vitamin D analogs; phototherapy; oral medications such as biologics; and lifestyle changes like stress management techniques [7].
