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.
