Platelet-rich plasma (PRP) has expanded its therapeutic applications into the field of aesthetic medicine. PRP is an autologous blood-derived product with an increased concentration of platelets to plasma relative to that of whole blood, which supports its therapeutic effects. Frequently promoted and marketed directly to consumers and patients, clinicians are often questioned on the efficacy and safety of PRP as a therapeutic modality. Given the rise in popularity of PRP, multiple clinical trials have been conducted to assess its application within the field of aesthetic medicine, particularly for hair loss con-ditions, skin rejuvenation, scarring, and conditions of dyspigmentation. We have reviewed the relevant research about the utility of PRP and associated evidence-based practices and discuss the direction for future research. (c) 2021 Elsevier Inc. All rights reserved.
