Psoriasis is a chronic skin disorder that causes itching and/or burning, scaling and crusting of the skin. Psoriasis cannot be cured but it can be treated successfully, sometimes for months or years at a time. The most common treatments are topical medications, phototherapy, photochemotherapy (PUVA), and oral or injectable medication (for severe symptoms). Dr. Prystowsky specializes in topical treatment of psoriasis, phototherapy, and oral treatment with acitretin or Otezla. If you require a biologic injectable agent, she will refer you to a specialist.
