A 308 nm excimer light is an effective treatment for vitiligo, with fewer treatment times, rapid obvious effects, relatively complete pigment recovery, good patient compliance, and safe and effective treatment for children. The disadvantage of this treatment is that some patients have a plateau during which the skin lesion reduction rate slows down or stalls after multiple treatments. Treatment data were collected from all vitiligo patients in the Dermatology Department, distinguishing between those who underwent 308 nm excimer light treatment alone and those who received a combination of 308 nm excimer light and 2940 erbium laser treatment. Of the 104 patients, 60 were treated with 308 nm excimer light only, and 44 were treated with a combination of a 2940 erbium laser and 308 nm excimer light. In contrast to the treatment of 308 nm excimer light alone, the combined treatment of the 2940 erbium laser and 308 nm excimer light significantly increased the speed and degree of repigmentation in vitiligo. Our study demonstrates that the combination of 308 nm excimer light and 2940 nm erbium laser treatment can improve the treatment response for vitiligo, decrease the occurrence of treatment plateaus associated with 308 nm excimer light, and improve efficacy.
