[摘 要]目的 探究痤疮后凹陷性瘢痕患者采用果酸联合CO2点阵激光治疗的效果。方法 选取2023年2月-2024年2月我院收治的痤疮后凹陷性瘢痕患者70例作为研究对象，以随机抽签法分为对照组和研究组，每组35例。对照组采用CO2点阵激光治疗，研究组采用果酸联合CO2点阵激光治疗，比较两组治疗效果、不良反应发生率、GAGS评分。结果 研究组治疗总有效率为97.14%，高于对照组的80.00%(P<0.05)；研究组治疗后GAGS评分低于对照组(P<0.05)；研究组不良反应发生率为5.71%，低于对照组的22.86%(P<0.05)。结论 果酸联合CO2点阵激光治疗痤疮后凹陷性瘢痕的效果良好，能避免患者出现皮疹、皮肤红肿、色素沉着等情况，减轻患者痤疮后凹陷性瘢痕症状。
