Narrowband Ultraviolet Light Therapy
Narrowband Ultraviolet Light B Therapy (NBUVB) is the most common form of phototherapy used to treat skin diseases. “Narrowband” refers to a specific wavelength of ultraviolet (UV) radiation, 311 to 312 nm. These wavelengths have the most benefit in treating skin conditions. This treatment is administered in our office by a medical assistant or a nurse. Typically, the patient undresses to expose the affected areas of their skin to the ultraviolet light. The patient stands in a treatment booth called a light box, the walls of which are lined with UVB bulbs. Narrowband UVB treatments are short – they typically last seconds to minutes. Narrowband UVB treatment is typically done 2-3 times per week and is used for a variety of skin conditions including psoriasis, eczema, mycosis fungoides, and itching.
