In-Office Treatments We can discuss the new immune system modifiers for psoriasis and the accepted immune suppression treatments for your disease. There are multiple topical options including steroids and retinoids that can be offered and discussed. Narrow Band UVB: Sunlight and ultraviolet light slow the rapid growth of skin cells. Psoriasis patients are directed to carefully sunbathe. People with psoriasis all over their bodies may require treatment with light boxes for full body exposure. Our office is equipped with the latest light treatment technology available. PUVA/UVA PUVA: When psoriasis has not responded to other treatments or is widespread, PUVA is effective in 85 to 90 percent of cases. The treatment name comes from “Psoralen + UVA,” the two factors involved. Patients are given a drug called Psoralen, and are then exposed to a carefully measured amount of a special form of ultraviolet (UVA) light. excimer Laser: Topical targeted phototherapy (excimer laser) is indicated for adult and pediatric patients with mild, moderate, or severe psoriasis with <10% BSA involvement. Light Therapies take approximately 25 treatments, over a two- or three-month period, before clearing occurs. About 30-40 treatments a year are usually required to keep the psoriasis under control. Over a long period, light therapy increases the risk of skin aging and skin cancer. Our dermatologists monitor light treatments very carefully.
