Narrow-Band Ultraviolet B Light Therapy

Narrow-band ultraviolet B (NB-UVB) is a type of light therapy used in the treatment of certain skin conditions including psoriasis, mycosis fungoides, chronic dermatitis, and others. NB-UVB light treatments are given 2-3 times per week in the office. UVB light is naturally produced by the sun and is the type of light responsible for sunburns. To protect our patients we use a very controlled and narrow band of UVB light.

In our office we use a standing light cabinet with special bulbs that emit UVB rays. Patients stand unclothed in the light cabinet for the amount of time necessary to receive their calculated dosage of UVB light. Male patients must keep their genitalia covered at all times during treatment in the light booth. An athletic supporter is sufficient for coverage during treatments. Special glasses must be worn during the treatments and can be purchased from the office when starting your treatments.

Generally patients will receive about 6-8 weeks of treatment before seeing the doctor to check your progress. UVB light therapy is usually attempted after failures of other conventional therapies, such as topical ointments and creams. These therapies can also be used in conjunction with light therapy depending on the protocol established by your physician.

Treatments start at a very low dosage, usually only lasting a few seconds, and builds over time. The amount of UVB light you receive is carefully calculated to prevent burns, however they can still occur. Limiting exposure to sunlight can help reduce your chances of burning. If you feel you have been burned, please alert the nurse before taking your treatment.
