Abstract A port‐wine stain (PWS) is a congenital capillary malformation that is seen in 0.3–0.5% of newborns. Although many types of lasers have been used to treat PWSs, few studies have investigated the efficacy of 577‐nm Pro‐Yellow lasers. The aim of this study was to establish the efficacy of Pro‐Yellow lasers in PWS treatment. In total, 26 patients, comprising 15 females (57.7%) and 11 males (42.3%) with a mean age of 24.7 ± 11.8 (range 1–50) years were included in the study. All were treated with a 577‐nm Pro‐Yellow laser at 4‐week intervals, 3–10 times. The sessions initially used scan mode and a fluence dose of 24 J/cm 2 per session, on average. The mean dose was increased by 4 J/cm each session and the maximum dose administered was 44 J/cm 2 . A mean regression of 68.8 ± 13.9% in the size of the lesions over 5.23 ± 2.7 sessions was observed. There was no statistically significant difference between the female and male patients when they were compared in terms of the number of treatment sessions ( p = .789) and treatment success ( p = .39). These case series demonstrate that the Pro‐Yellow laser is a safe and well‐tolerated treatment for PWSs. However, deep‐seated lesions required more treatment sessions and it was observed that clinically the lesions did not completely disappear.
