Narrowband ultraviolet B phototherapy and 308-nm excimer laser in the treatment of vitiligo: A review

Vitiligo is a common and chronic disease with a great impact on patients' quality of life. Phototherapy with narrowband ultraviolet B radiation and excimer laser are two treatment modalities that are used increasingly for the management of the disease with variable results. In this article, we review the efficacy, adverse effects, and possible mechanisms of action of narrowband ultraviolet B and excimer laser in the management of vitiligo. Available data concerning the follow-up of treated patients and some criteria for the selection of patients with a greater chance to respond satisfactorily to treatment are also presented.
