Most studies evaluating platelet-rich plasma (PRP) injection for facial rejuvenation and other cosmetic procedures have reported positive results, according to a critical review in the May issue of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons (ASPS).

But the research evidence supporting PRP for facial aesthetic procedures has important limitations Рespecially a lack of standardized PRP preparation and injection techniques, concludes the report by ASPS Member Surgeon Alexes Hazen, MD, and colleagues of the Hansjörg Wyss Department of Plastic Surgery at NYU Langone Health, New York.

“More studies are needed to optimize PRP treatment techniques,” Dr. Hazen comments, “Until that time, our paper may be useful in guiding clinical practice.”
