The field of dermatology has seen numerous therapeutic innovations in the past decade, with platelet-rich plasma recently garnering significant interest in acne scarring. This review consolidates the available evidence on platelet-rich plasma for the practicing dermatologist and evaluates the current evidence up to May 31, 2018. A search was conducted in the PubMed database for the terms platelet-rich plasma or platelet releasate or platelet gel or PRP and dermatology or skin or acne or scar or cutaneous, with 13 articles meeting the inclusion criteria. The quality of each individual study was evaluated, and levels of evidence were assigned according to the Centre for Evidence-Based Medicine, Oxford, United Kingdom. This review reveals that activated, leukocyte- and platelet-rich plasma in combination with fractional ablative laser treatment administered in 2 or 3 sequential sessions 1 month apart improves the appearance of acne scars. The evidence for the use of platelet-rich plasma with microneedling is less supportive. Because of the heterogeneity of the studies and widely variable outcome measures, comparison between platelet-rich plasma treatments and subsequent statistical analysis could not be performed. Although these studies use various subjective and objective evaluation methods, the addition of platelet-rich plasma provides improvements in acne scarring, higher patient satisfaction, and decreased postprocedure downtime.

Platelet-rich plasma (PRP) has received attention for its ability to promote cell differentiation, proliferation, and regeneration.2,3 Many studies have evaluated the use of PRP for different dermatologic conditions, from androgenetic alopecia4 to acne scars.
