Abstract
Platelet preparations are autologous blood concentrates with supraphysiologic concentrations of platelets with or without leukocytes used in various clinical applications including regenerative medicine, wound healing, and facial rejuvenation. Their use harnesses the important role of platelets and their secretory products in immunoregulation, wound healing, angiogenesis, and tissue remodeling. The use of platelet preparations has been long documented in orthopaedic surgery, maxillofacial surgery, and other fields, but over the years research has increased in their application to facial plastic surgical techniques. Here we review the various formulations of platelet rich concentrates, their applications to facial skin rejuvenation, wound healing, scar reduction, and tissue fill as documented in the literature since 2018.
