Verruca plana is a cutaneous infection caused by the human papilloma virus. Although various treatment methods are currently available, most have limitations due to the risk of complications such as hyperpigmentation, edema, and scarring. Moreover, as the infection tends to spread easily, new verrucae can potentially develop, and treatment procedure times tend to be lengthy. Thus, novel treatment methods are required. The 2790­nm wavelength erbium:yttrium–scandium–gallium–garnet (Er:YSGG) laser is a superficial resurfacing laser. Here, we present a case of a 25­year­old woman with multiple verrucae treated using a 2790­nm Er:YSGG laser. Compared to traditional methods, this novel laser is convenient, produces better cosmetic outcomes, and is less time­consuming; it is therefore suitable for the treatment of facial verruca plana.
