Narrowband UVB is a type of light therapy, or phototherapy, that uses a specific wavelength of ultraviolet light to calm inflammation in the skin. It is a well-established treatment for several skin conditions, and it does not require medicine by mouth or injection.
Narrowband UVB is offered at our Upper East Side and Greenvale offices.

What to expect
You stand in a light booth, or place a hand or foot in a smaller unit, for a short treatment that starts at seconds and builds up to a few minutes. You wear goggles to protect your eyes. Most people come 2 to 3 times a week. Improvement usually shows after several weeks.

Q&A
Does it hurt?
Treatment is usually painless while the light is on, but redness, itching or burns can occur afterward. Tell your provider about any reaction before your next session.
Does it raise my skin cancer risk?
Long-term risk is not fully established and depends on factors such as cumulative exposure and prior skin cancer. Your provider will review your history, track treatment exposure and discuss monitoring.
Is it covered by insurance?
Many plans cover phototherapy for approved conditions. We can help you check.
