Poolsuwan P, et al. - In this randomized, single‐blind comparison study, researchers sought to compare the effectiveness of 308‐nm excimer light and 311‐nm NB‐UVB in patients with symmetrical vitiligo lesions. Thirty-six symmetrically paired vitiligo lesions were recorded in the same anatomical region. Localized 308 nm excimer light was treated on one side of the symmetrical lesions and targeted 311 nm NB-UVB assigned randomly by computer was treated on the opposite side. Thirty-six symmetrical vitiligo lesions were randomly treated, with 308-nm excimer light on one side and 311-nm NB-UVB on the opposite side. For the treatment of vitiligo, localized 308‐nm excimer light tends to be more powerful and also causes repigmentation more rapidly than targeted 311-nm NB-UVB.
