Narrow Band UVB
Narrow–Band UVB is a common form of phototherapy used to treat skin disorders. It was developed after PUVA, and has shown improvement in patient results. The narrow–band UVB works by releasing a small range of ultraviolet light through an apparatus onto the skin.
It is most commonly used for Psoriasis and eczema, which will decrease in thickness after 5-10 sessions (results vary).
Treatment results will vary, talk to a practitioner to see if this treatment or procedure is right for you.
