Abstract

Background - Platelet-rich plasma (PRP) as a non-surgical therapy for facial rejuvenation is increasingly adopted. This article aims to review the literature and critically appraise the available evidence regarding the efficacy and safety of PRP for facial rejuvenation.

Material and methods - An overview of systematic reviews (SRs) of PRP use for facial rejuvenation. The methodological quality of the SRs was assessed using the AMSTAR-2 checklist; quality of the evidence from the trials included in each SR was appraised following the GRADE approach.

Results - Thirteen SRs published between 2015 and 2023, reporting data from 114 overlapping reports, based on 28 individual primary studies (18 uncontrolled reports), were included in this umbrella review. Eight primary studies evaluated PRP in combination with other treatments (laser therapy, fat grafting, hyaluronic acid, basic fibroblast growth factor), and 20 PRP monotherapy. Meta-analysis conducted in only 1 of the 13 SRs, showing that patients treated with PRP as an adjunct treatment have increased satisfaction over controls without PRP (mean difference, 0.63; 95% confidence intervals (CIs) 0.25/1; p=0-001; low certainty of evidence due to risk of bias (ROB) and inconsistency). No other quantitative data were available from the SRs, although 4 SRs reveal that PRP combined with laser therapy increased subject satisfaction and skin elasticity and decreased the erythema index (very low certainty of evidence due to imprecision, unsystematic clinical observations, and ROB). Adverse events was a predefined outcome in only 2 SRs (15%). Almost all the SRs demonstrated poor compliance with the AMSTAR 2 items, and the confidence in the results of SRs was graded as low or critically low in 12 of the 13 SRs.

Discussion - The available evidence is insufficient to suggest firm conclusions about the use of PRP, alone or in combination with other treatments, in promoting facial rejuvenation.
