A comparative clinical trial to evaluate efficacy and safety of the 308‐nm excimer laser and the gain‐switched 311‐nm titanium:sapphire laser in the treatment of vitiligo

Abstract

Ultraviolet B (UVB) laser irradiation in a targeted manner is a reasonable treatment option for localized vitiligo. Recently, narrow‐band UVB gain‐switched 311‐nm titanium:sapphire lasers (TSL) were developed for the treatment of localized vitiligo. We aimed to compare efficacy, patient satisfaction, and safety between the conventional 308‐nm excimer laser (EL) and gain‐switched 311‐nm TSL in patients with vitiligo.
