Treatment of Acne Scars with Microneedling

Background: Inflammatory acne lesions can result in permanent scars, the severity of which may depend on delays in treating acne patients. Over the years, various descriptive terms have been used to classify different types of acne scars. The simplest and most universally accepted classification system categorizes acne scars into three main types: icepick scars, rolling scars, and boxcar scars. Different treatment modalities are available with variable efficacies. Aim of the work: The aim of this study is to evaluate the efficacy of microneedling in the treatment of acne scars. Materials and methods: The study was conducted on 20 volunteers expressing various types of acne scars. Their ages ranged from 27 to 39 years. Patients were subjected to 6 sessions of microneedling at 2-week intervals. Results: There was statistically significant difference as regards the number of rolling, icepick and boxcar scars when compared to baseline. Facial swelling, mild discomfort and erythema were observed by all patients following the treatment; however, these side effects subsided within one day. Conclusion: In treatment of atrophic acne scars, this study demonstrated that microneedling was effective with mild transient side effects.
