GlossaryNarrowband UVB (Narrowband Ultraviolet B)

specific UVB light therapy for treating skin conditions

Narrowband UVB (NB-UVB) refers to a specific type of ultraviolet light therapy that uses a narrow range of UVB wavelengths, typically around 311-313 nanometers. This treatment is commonly used to manage skin conditions such as psoriasis, vitiligo, and certain types of eczema, as it can reduce inflammation and promote repigmentation with fewer side effects compared to broadband UVB therapy.
