Platelet-rich fibrin matrix

The "platelet-rich fibrin matrix" (PRFM) method is a cosmetic surgery procedure involving plasma needling. It is a way of extracting platelets from the patient's own blood and using them as a dermal filler – that is, as a substance injected under the skin of the face to try to fill out wrinkles.
