Summary The 595‐nm pulsed dye laser (PDL) is one of the newest developments in the treatment for port‐wine stains (PWS). The aim of this study was to investigate the effectiveness of the treatment of PWS in Chinese patients using the 595‐nm PDL. In total, 184 patients with PWS over the face, neck and trunk or limbs were enrolled in the study. All the patients were treated with the 595‐nm PDL 3–6 times, with a 4‐week interval between each treatment. Treatment parameters varied for each patient according to the colour and location of the PWS. The efficacy of treatments and any side‐effects were evaluated. Results were graded as percentage resolution (0–25%, 25–50%, 50–75% and 75–100%). Of the 184 patients who completed the study, 115 (62.5%) achieved excellent improvement, 38 (20.7%) achieved good results, and 31 (16.8%) had an unsatisfactory outcome (moderate and poor response). We found > 75% improvement for 76% of facial PWS (95/125), 43% of neck PWS and 20.8% of trunk or limb PWS. Pain and topical erythema were commonly reported immediately after the laser treatments. Prominent hyperpigmentation occurred in only 11 cases (6.0%) with poor improvement, and resolved within 6 months. The 595‐nm PDL appears to be safe, effective and well tolerated in the treatment of PWS in Chinese patients.
