Acne scars are an unwanted reminder of past acne. They constitute a significant esthetic and psychosocial problem, negatively affecting the quality of life of patients. There are many methods used to treat acne scars. One of them is fractional CO laser treatment, which stimulates the skin to produce collagen. The main aim of this study was to verify, based on the available literature, the effectiveness of fractional CO laser treatment of acne scars and to determine the potential risk associated with the use of this therapeutic method. The literature review includes English-language articles selected using keywords and inclusion and exclusion criteria. In order to select appropriate sources, databases such as PubMed and Google Scholar were searched. The systematic review included seven studies that assessed the effectiveness of fractional CO laser therapy for acne scars. Most patients experienced a 30% to 70% improvement in the appearance of their scars. The most commonly reported adverse events during treatment were transient erythema, edema, and post-inflammatory hyperpigmentation, which resolved within a few weeks. Fractional CO laser therapy is an effective and safe treatment for acne scars. However, despite the abundance of evidence, there is a need for further studies focusing on long-term monitoring of patients.
痤疮疤痕是过去痤疮留下的令人烦恼的痕迹。它们构成了一个重大的美学和心理社会问题，对患者的生活质量产生负面影响。治疗痤疮疤痕有许多方法。其中之一是分次二氧化碳激光治疗，它能刺激皮肤产生胶原蛋白。本研究的主要目的是根据现有文献验证分次二氧化碳激光治疗痤疮疤痕的有效性，并确定与使用这种治疗方法相关的潜在风险。文献综述包括使用关键词以及纳入和排除标准筛选出的英文文章。为了选择合适的来源，检索了诸如PubMed和谷歌学术等数据库。系统评价纳入了七项评估分次二氧化碳激光治疗痤疮疤痕有效性的研究。大多数患者的疤痕外观改善了30%至70%。治疗期间最常报告的不良事件是短暂性红斑、水肿和炎症后色素沉着，这些在几周内就会消退。分次二氧化碳激光治疗是一种治疗痤疮疤痕有效且安全的方法。然而，尽管有大量证据，但仍需要进一步开展侧重于对患者进行长期监测的研究。
