Background:
Microneedling (MN) has risen in popularity as a non-surgical treatment option for facial skin aging. We aimed to evaluate patient-reported outcomes (PROMs) and safety profiles associated with MN.
Methods:
A systematic review was conducted adhering to PRISMA guidelines. Articles were screened for relevance in a two-stage process. Descriptive statistics and a proportion meta-analysis was utilized for patient satisfaction using Stata statistical software.
Results:
Of 346 studies identified, a total of 21 articles reporting outcomes of 723 patients undergoing MN for facial rejuvenation were included for review and meta-analysis. The patient cohort was majority female (72%), and the average age was 48 years. The most common esthetic study endpoints were wrinkling (71%, 15/21), skin texture (33%, 7/21), photoaging (29%, 6/21), and skin laxity (14%, 3/21). The majority of trials (90%, 19/21) treated patients with multiple MN sessions, and these studies' treatment schedules also varied by number and timing of sessions. Pooled meta-analysis revealed that 83% of patients reported satisfaction with their treatment (95% CI [0.76; 0.88]). The most common reported adverse effects were transient erythema (6.8%), scaling (1.7%), burning sensation (1.5%), and pruritus (0.4%).
Conclusion:
Our meta-analysis revealed that MN is associated with high patient satisfaction and low rates of adverse events. High patient satisfaction coupled with a low incidence of adverse events supports MN as a viable non-surgical treatment option for facial rejuvenation. However, the lack of standardized measures for esthetic outcomes warrants continued research to better determine its efficacy in treating signs of facial aging.
