Microneedling is a popular, minimally invasive skin rejuvenation modality for acne scarring. Recent reports have evaluated the efficacy and safety of microneedling monotherapy and combination treatment for scarring.
This review aims to systematically analyze the current literature on microneedling techniques used for acne scarring.
A PubMed search (2009-current) was used to identify literature on microneedling treatment for acne. All randomized and nonrandomized clinical trials, case cohorts, case reports, and case series were included with the exception of 2 studies, which were excluded due to unavailability.
All 33 articles evaluated showed improvement of acne scar appearance after microneedling treatment. Evidence was inconsistent when comparing microneedling monotherapy to dual therapy or to fractional laser treatment.
Microneedling improves acne scarring, and further studies are needed to compare microneedling with other minimally invasive treatments.
微针是一种流行的微创皮肤年轻化方法，可用于治疗痤疮瘢痕。最近有报道评估了微针单独治疗和联合治疗瘢痕的疗效和安全性。
本综述旨在系统分析微针技术治疗痤疮瘢痕的现有文献。
使用 PubMed 检索（2009 年至今），以确定有关微针治疗痤疮的文献。所有随机和非随机临床试验、病例队列、病例报告和病例系列均被纳入，仅有 2 项研究因无法获取而被排除。
所有 33 项评估研究均表明，微针治疗后痤疮瘢痕外观得到改善。当比较微针单独治疗与双治疗或与分激光治疗时，证据并不一致。
微针可改善痤疮瘢痕，需要进一步的研究来比较微针与其他微创治疗方法。
