What is Narrow Band UVB?
Narrowband UVB 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. UVB phototherapy was formerly provided as a broadband source (290 to 320 nm).
Is Narrow Band UVB safe?

What is narrowband UVB phototherapy and how does it work?
However, it is also the waveband that is most effective in treating diseases of the skin. In narrowband UVB phototherapy, we aim to maximize the treatment benefits of UVB light and minimize the short and long-term problems that can result from exposure to this light.
What is the difference between uvnarrowband and UVB?
Narrowband refers to a specific limited set of wavelengths of UV light, 308 to 312 nm, that has proved to be the most beneficial component of natural sunlight for treating skin disease. UVB light is the portion of sunlight responsible for producing a sunburn, a suntan, burning of the eyes, skin cancer and aging changes in the skin.
