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.
Platelet-rich plasma (PRP), also known as autologous conditioned plasma, is a concentrate of plasma protein derived from whole blood, centrifuged to remove red blood cells but retaining platelets. Though promoted for treating various medical conditions, evidence of its benefits was mixed as of 2020 , showing effectiveness in certain conditions ...
Platelet-rich fibrin (PRF) or leukocyte- and platelet-rich fibrin (L-PRF) is a derivative of PRP where autologous platelets and leukocytes are present in a complex fibrin matrix [1] [2] to accelerate the healing of soft and hard tissue [3] and is used as a tissue-engineering scaffold in oral and maxillofacial surgeries.
This procedure has been deemed controversial at times, especially when used by athletes.In 2005, the World Anti-Doping Agency ruled that blood-spinning could be used to introduce banned substances, [2] and in 2010 the agency went as far as banning the use of intramuscular injections of PRP in competitive athletes amid some concerns that it boosted performance-enhancing growth factors.

They are given by injection into a vein. [4] Side effects can include allergic reactions such as anaphylaxis, infection, and lung injury. [2] Bacterial infections are relatively more common with platelets as they are stored at warmer temperatures. [2] Platelets can be produced either from whole blood or by apheresis. [1]

Plateletpheresis (more accurately called thrombocytapheresis or thrombapheresis, though these names are rarely used) is the process of collecting thrombocytes, more commonly called platelets, a component of blood involved in blood clotting.
Platelet storage pool deficiency is a family of clotting disorders characterized by deficient granules in platelets.Individuals with these disorders have too few or abnormally functioning alpha granules, delta granules, or both alpha and delta granules and are therefore unable to form effective clots, which leads to prolonged bleeding.
