Autologous platelet-rich plasmaPRP is your own blood, drawn and spun to concentrate the platelets and the growth factors they carry, then re-injected. It is used for skin quality, under-eye hollowing and early hair thinning, usually as a series of three sessions.
A small volume of blood is drawn, then centrifuged so the platelet-rich fraction separates from red cells and platelet-poor plasma. A double spin concentrates the platelets further than a single pass. The resulting plasma is injected into the area being treated.
Platelets carry growth factors — the signalling molecules released during ordinary wound healing. Concentrating and delivering them into the dermis or scalp is intended to recruit the same repair response without an injury to justify it: fibroblast activity, new collagen, improved local blood supply.
Because it is made from your own blood there is no foreign material and no allergy risk. It also means the quality of the preparation varies with the person and the method, which is part of why protocols differ between clinics.
Thin, crêped and faintly hollow under-eye skin is difficult to treat. Filler there can look heavy or go blue, and lasers are limited by how little skin there is. PRP works on the quality of the skin instead, which suits the area well — though it will not remove a true tear-trough shadow caused by bone and fat.
Across the face, PRP is often paired with microneedling so the channels deliver the plasma into the dermis directly. The usual target is overall texture, pore appearance and early fine lines.
Injected into the scalp, PRP is used in early androgenetic hair thinning, where miniaturising follicles are still present. The evidence is stronger here than for some other PRP indications. It does not restore follicles that have been gone for years, and it works best alongside medical treatment rather than instead of it.
The appointment takes longer than a straightforward injection because the blood has to be drawn and spun first. Expect swelling afterwards, and bruising under the eyes in particular — most people allow a few days before anything social.
Results are progressive rather than immediate, and it is a course: three sessions roughly a month apart is the usual starting point, with maintenance afterwards depending on what is being treated.
Questions
Usually three, around a month apart, with maintenance afterwards depending on the area. A single session is rarely enough to judge it by.
It improves the quality of thin, crêped under-eye skin, which often makes the area look less shadowed. It does not fill a true tear trough caused by bone and fat loss — that is a different problem with a different answer.
It is used for early androgenetic thinning where follicles are miniaturising but still present, and the evidence there is reasonably good. It does not regrow hair from follicles that have been absent for years, and it is generally used alongside medical treatment rather than in place of it.
It is prepared from your own blood, so there is no foreign material and no allergy risk. Swelling and bruising are expected. Some blood conditions and medications rule it out, which is established at the consultation.
Microneedling is the controlled injury; PRP is the biological material. They are frequently combined, because the channels made by microneedling let the plasma reach the dermis directly.
Bring your concern rather than a treatment name. The assessment decides what is actually indicated, and what is not.
