What Is Platelet-Rich Fibrin (PRF) Therapy?

Platelet-Rich Fibrin (PRF) is prepared from peripheral blood using centrifugation designed to create a platelet- and cell-containing fibrin matrix. Unlike many PRP methods, PRF commonly omits anticoagulant, so collection-to-spin timing and time-to-use strongly affect whether it remains injectable or forms a clot, membrane, or gel.

Not one standardized product

Leukocyte-PRF, advanced PRF, injectable PRF, and concentrated growth factor reflect different tubes, speeds, forces, times, and harvest layers. RPM alone is insufficient because rotor radius changes relative centrifugal force.

Evidence depends on use

PRF has established research and clinical use in parts of oral and maxillofacial care, while musculoskeletal, hair, and aesthetic evidence is less standardized. A dental membrane cannot automatically support an injectable joint or facial product.

PRF versus PRP

PRP typically uses anticoagulated blood and remains liquid unless activated. PRF develops a fibrin network and may contain more leukocytes depending on protocol. Neither is uniformly better.

Safety

Autologous blood reduces donor-disease and some allergy concerns but does not prevent contamination, wrong-patient errors, bleeding, infection, nerve or vessel injury, or reactions to additives.
