Abstract

Background: Multiple treatments are used to treat acne scars, but comparing the effectiveness of these treatments have not been studied yet. This research aimed to conduct a complete analysis of the effectiveness of commonly used therapies in acne scars.

Methods: PubMed, Embase, and Cochrane's Library (Cochrane Center Register of Controlled Trials) databases were searched through May 2023. We used patient satisfaction score as the primary outcome and Goodman Baron qualitative scar grading system as the secondary outcome to evaluate the effectiveness of different commonly used therapies for acne scarring, including laser, microneedling (MN), platelet-rich plasma (PRP), autologous fat grafting and combined therapies.

Results: Herein, 495 patients from 13 studies were included. Our results showed that PRP combined with laser was the most effective among therapies in treating acne scars. Ranking of effectiveness by the surface under the cumulative ranking (SUCRA) curve for patient satisfaction score was as following: PRP + laser (96.2%) > laser (71.2%) > MN (45.5%) > MN + PRP (42.0%) > autologous fat grafting (24.5%) > PRP (20.5%). Additionally, ranking of effectiveness by the SUCRA curve for Goodman Baron qualitative scar grading system was as following: PRP + laser (86.3%) > laser (64.2%) > MN + PRP (54.2%) > MN (37.2%) > PRP (8.1%).

Conclusion: This network meta-analysis indicated that the combined therapy of PRP and laser might be the most effective. Additionally, more high-quality randomized controlled trials are needed to verify our findings.
