Various treatment modalities have been applied to atrophic scars. Fractional CO₂ laser treatment has attracted increasingly more attention because of its quicker recovery time and fewer side effects. However, its limitation of sculpting the edge is an urgent shortcoming. In order to achieve a more effective result with fewer complications, we have integrated ultrapulse CO₂ and fractional CO₂ lasers to for the treatment of facial atrophic scars. The study included 25 patients (10 males and 15 females) diagnosed with moderate to severe atrophic scars between August 2020 and July 2022. All subjects underwent the same surgical treatment. The effects were assessed at baseline, 1 week, 1 month, and 3 months using photographic evidence. Objective evaluation of the results was conducted using a quartile grading scale, while the subjects’ satisfaction and any adverse events were also recorded. The patients in the study underwent more than two laser sessions (2–5), resulting in substantial improvement in their appearance. The time interval between each session was 3–6 months. The majority of the patients (19/25, 76%) had a significant or even excellent improvement. Any adverse events observed, such as erythema, superficial crusting, and PIH, were of a mild nature and temporary in duration. This treatment combined two CO₂ lasers is an effective and safe choice for atrophic scars in Asians.

各种治疗方式已应用于萎缩性疤痕。点阵CO ₂激光治疗因其恢复时间快、副作用少而受到越来越多的关注。然而，其雕刻边缘的局限性是一个紧迫的缺点。为了达到更有效、更少并发症的效果，我们整合了超脉冲CO ₂和点阵CO ₂激光来治疗面部萎缩性疤痕。该研究纳入了 2020 年 8 月至 2022 年 7 月期间被诊断患有中度至重度萎缩性疤痕的 25 名患者（10 名男性和 15 名女性）。所有受试者都接受了相同的手术治疗。使用照片证据在基线、1 周、1 个月和 3 个月时评估效果。使用四分位分级量表对结果进行客观评价，同时还记录受试者的满意度和任何不良事件。研究中的患者接受了两次以上的激光疗程 (2-5)，其外观得到了显着改善。每次疗程之间的时间间隔为3-6个月。大多数患者（19/25，76%）有显着甚至极好的改善。观察到的任何不良事件，如红斑、表面结痂和妊娠高血压综合征，性质轻微且持续时间短暂。这种结合两种 CO ₂激光的治疗方法是治疗亚洲人萎缩性疤痕的有效且安全的选择。
