Both PRP (platelet rich plasma), and PRF (platelet rich fibrin) are platelet based growth factor treatments that are extracted using centrifuge. PRF is different from PRP in that there is no anticoagulant added during the spin, the avoidance of clotting is physiological and is achieved through negative charge of the collecting tube to mimic the conditions within our own blood vessels (their lining is negatively charged) that prevent fibrin from creating a clot within them, thus, obtaining a platelet rich injectable fibrin. Once PRF is injected in the tissue it transforms from liquid into a gel, which not only lead to filling of voids in folds and wrinkles but also provide a powerful regenerative matrix that releases platelets’ growth factors in a physiological controlled slow manner that enhances tissue regeneration is a better way than PRP. In addition, the enrichment of platelets in these two products is not the same. In PRP, the platelets are enriched two to four times above the physiological concentrations available in blood and there are very few circulating blood stem cells. In contrast, PRF contains all the platelets with no elimination of the powerful regenerative matrix (fibrin) in addition to another very rich source of growth factors and tissue regeneration: the circulating blood regenerative cells.
