Narrowband UVB is a newer method of laser therapy that minimizes side effects by using a more specific UV radiation of 310-315 nm, which is concentrated more in the therapeutic range, therefore reducing sunburn and overall exposure to ultraviolet light. It is used for a wide range of treatments and is regarded safer than the prior broadband UVB.

Advantages of Narrowband UVB

- Shorter, safer exposure time

- More effective in treating skin conditions

- Produces longer remissions
