Autologous platelet-rich plasma

PRP

PRP 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.

What it is
Autologous platelet-rich plasma, prepared from your own blood on the day
Also called
双倍离心血清
Treats
Skin texture and tone, under-eye hollowing and crêping, early hair thinning
Course
Usually three sessions, around a month apart
Visible
Progressive, over two to three months
Downtime
Swelling and bruising, most noticeable under the eyes
Contains
Nothing but your own blood components

How PRP is prepared and what it does

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.

Where it is used

Under the eyes

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.

Skin texture and tone

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.

Early hair thinning

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.

What to expect

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.

Who it suits, and who it does not

Questions

Questions patients ask

How many PRP sessions do I need?

Usually three, around a month apart, with maintenance afterwards depending on the area. A single session is rarely enough to judge it by.

Does PRP help under-eye hollows?

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.

Does PRP work for hair loss?

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.

Is PRP safe?

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.

What is the difference between PRP and microneedling?

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.
