Background: The emergence of acne scars due to skin damage in the acne healing process and causes psychological effects. The management of acne scars can be done in several methods. Microneedling is a very simple, safe, effective, and minimally invasive therapeutic technique compared to other therapeutic modalities in acne scars. The resulting wound is micro-sized, and promotes the growth of growth factors and collagen production. We aimed to assess the effectiveness of using microneedling as an acne scar treatment option. A systematic review and meta-analysis were qualitatively and quantitatively conducted from RCTs, assessing the effectiveness of microneedling in reducing the severity of acne scars according to Goodman and Baron in the treatment of acne scars.
Methods: Medline Pubmed, PMC, Scopus, Google Scholar, and JDC library, eligible search. Ten studies (n=514) were analyzed qualitatively with 2 studies (n=53 subjects) and quantitatively analyzed by 2 studies (n=90 subjects). Both analyzes were included in the meta-analysis. The mean age of the participants was 40.5 years. The application of microneedling intervention as monotherapy or a combination in patients with acne scarring was followed for at least 16 weeks, the results obtained were the mean reduction in the degree of acne scarring after microneedling.
Result: The combination of microneedling treatment obtained a qualitative decrease in the degree of acne scars according to Goodman and Baron with a Z value (-4.299) and P=<0.001 lower than the control (PRP) with a significant difference. The quantitative decrease in the degree of acne scars according to Goodman and Baron obtained a Z value (-4.681) and P=<0.001 lower than the control (PRP) with a significant difference. Quantitative reduction in the degree of acne scars according to Goodman and Baron on single therapy between treatment and control with a value of Z (-3.536) and P=<0.001 lower than control (fractional CO2) with a significant difference. The results of the degree of acne scars in the group treated with microneedling alone or in combination were lower than the control group. The mean before and after therapy compared to the control there was a significant difference.
Conclusion. The results of a systematic review, concluded that the group treated with microneedling had a decrease in the degree of acne scarring according to Goodman and Baron with P=<0.001 compared to before treatment. The decrease was shown in the difference in Z values, which was significantly greater than the control given other therapies. Microneedling therapy can be an alternative therapy option for acne scar patients who are unresponsive to previous therapy or in conditions where there are contraindications to other therapies.
