Background: Acne scars are frequent and result in impairment of mental health and quality of life among affected individuals. The use of platelet-rich plasma (PRP) has been recently proposed as part of acne scarring management. Objective: To synthesize the primary evidence regarding the efficacy and safety of PRP as an adjuvant treatment of atrophic acne scars. Methods: We carried out a systematic review and meta-analysis of controlled clinical trials. We performed a primary search on PUBMED-MEDLINE, WEB OF SCIENCE, WEB OF SCIENCE-MEDLINE, EMBASE, SCOPUS, and CENTRAL. Moreover, we searched clinical trial registries from the United States of America, Europe, and of the World Health Organization (WHO) as well as gray literature repositories until December 2019. We used the Cochrane tool for assessing risk of bias. We estimated relative risks (RR) with 95% confidence interval (CI) using random-effects models. Results: From 547 registers, we included 14 clinical trials (n=429). The PRP group showed a significantly higher clinical improvement compared to the control group in the studies using quartile grading scales (RR=1.79; 95%CI 1.39–2.31; I2=21.7%; p<0.001) and in the studies using the qualitative scarring grading system of Goodman and Baron (RR=4.34; 95%CI 1.60-11.76; I2=29.1%; p<0.001). Furthermore, the patient satisfaction was higher in the PRP group compared to the control group (RR=1.52; 95%CI 1.20-1.93; I2=51.1%; p=0.001). In the subgroup analysis, the PRP group with microneedling obtained a larger effect size in terms of clinical improvement and patient satisfaction (RR=2.66; 95%CI 1.72-4.11; I2=0.0%; p<0.001; RR=1.67; 95%CI 1.09-2.54; I2=69.9%; p<0.05, respectively). In addition, the split-face group had a larger effect size in terms of patient satisfaction (RR=1.58, 95%CI 1.11-2.24; I2=65.6%; p<0.05). Regarding the safety of the PRP, we did not perform a meta-analysis due to the high clinical and methodological heterogeneity in the reporting of adverse effects. Seven publications concluded that the duration and intensity of erythema, edema, and pain was less in the PRP group, while four investigations reported no significant difference for both groups. Conclusions: Evidence from controlled clinical studies suggests that in the management of atrophic acne scars, the use of PRP as an adjuvant treatment is more effective and safer than receiving monotherapy. Also, the combination of PRP with micro-needles has more effect than other combinations. The occurrence, duration, and intensity of adverse effects are equal or less with the use of PRP as an adjuvant therapy compared to receiving monotherapy. There is a need for further randomized controlled trials with larger sample sizes, standardized protocols for the use of PRP, and uniform outcome measurement scales.
