PRP is the abbreviation of platelet-rich plasma, and its Chinese name is "high concentration platelet plasma". PRP is a kind of high concentration plasma rich in platelets, which is made from self-blood. Human platelets can produce protein (fibronectin, Chinese name: fibronectin) with cell adhesion function at high concentration, which can promote platelets to secrete a large number of nine growth factors to promote wound, tissue healing and cell regeneration, so PRP is also called "plasma rich in growth factors" [PRGFS]. PRP can quickly stop bleeding, relieve pain, accelerate wound healing, and greatly reduce postoperative scar formation. Since the mid-1990s, PRP has been widely used in various surgical operations, heart surgery and plastic surgery, as well as medical beauty.
