what treats psoriasis
There are several effective topical treatments for psoriasis. While many can be purchased over the counter (OTC), others are available by prescription only. Corticosteroids, or just steroids, are the most frequently used treatment for psoriasis. They are referred to as anti-inflammatory agents, because they reduce the swelling and redness of lesions. Anthralin, synthetic vitamin D3, and vitamin A are also used in prescription topical treatments to control psoriasis lesions. OTC topicals come in many different forms. Two active ingredients, salicylic acid and coal tar, are approved by the FDA for the treatment of psoriasis.
