Also referred to as light treatments, phototherapy is a dermatology-directed use of narrow band ultraviolet B light to treat a variety of skin conditions. In fact, it is a reason that other dermatologists refer patients to our office. Some conditions that are treated with phototherapy include psoriasis, vitiligo, eczema, itching, and T-cell skin lymphomas. Phototherapy is administered in a stand-up unit in our office. At times, patients will purchase a phototherapy unit for their home. Narrow Band UVB is safer and more effective than tanning beds.
