Few clinic treatments sound quite as science-fiction as one that draws a little of your own blood, spins it down, and puts the concentrated part back into your skin or scalp to encourage repair. Platelet-rich plasma — almost always shortened to PRP — has become a fixture on aesthetic menus, from “vampire facials” to hair-restoration programmes. It is genuinely interesting, but it is also frequently oversold. This guide explains what PRP actually is, where the evidence is stronger and weaker, and how to judge a clinic that offers it.
What is PRP?
Platelet-rich plasma is a concentrated preparation made from a small sample of your own blood. Blood is mostly red cells, white cells, plasma and platelets. Platelets are best known for helping blood to clot, but they also carry growth factors — signalling proteins that help direct tissue repair. The idea behind PRP is to concentrate those platelets and deliver them to an area you want to stimulate, whether that is ageing facial skin or thinning hair.
Because PRP is made from your own blood — it is autologous — the risk of an allergic reaction or rejection is very low, and there is no synthetic filler or medicine involved. That is a large part of its appeal. It is worth being clear-eyed, though: concentrating growth factors is not the same as guaranteeing they will rebuild tissue, and that gap between a plausible mechanism and a proven outcome is exactly where honest expectation-setting matters.
How the treatment works, step by step
A typical PRP appointment follows a familiar sequence:
- A practitioner draws a small sample of blood from your arm, much as they would for a routine blood test.
- The sample is placed in a centrifuge and spun at speed, which separates the blood into layers and concentrates the platelets within the plasma.
- The platelet-rich portion is drawn off and, depending on the goal, either injected into the target area or applied to the skin in combination with microneedling, which creates tiny channels for it to reach.
The whole process usually takes under an hour and is done in a single visit. Numbing cream is commonly applied before injections or microneedling to keep any discomfort manageable.
PRP for skin and facial rejuvenation
In aesthetics, PRP is used to try to improve skin quality — tone, texture, fine lines and a general sense of freshness — rather than to add volume the way a filler does. It is often applied across the face, and frequently to delicate areas such as under the eyes, where some people prefer to avoid filler. Practitioners commonly pair it with microneedling (the combination sometimes marketed as a “vampire facial”), on the reasoning that the two may complement one another.
What to expect is gradual and subtle. Rather than an instant change, any benefit tends to build over several weeks as the skin responds, and it is typically maintained with repeat sessions rather than being a one-off. PRP is best thought of as a skin-quality treatment — not a substitute for treatments that lift or add volume.
PRP works with your body’s own repair processes, so it rewards patience and realistic expectations — think gradual refinement, not a dramatic overnight result.
PRP for hair restoration
PRP’s other main use is for hair thinning, most often for pattern (androgenetic) hair loss in both men and women. The theory is that concentrated growth factors, injected into the scalp, may help support struggling follicles and prolong the active growth phase of the hair cycle.
This is the area where clinical interest has been most encouraging, but two honest caveats matter. First, PRP appears to work best for people with early or moderate thinning who still have living follicles to support — it cannot revive areas that are already completely bald. Second, it is not a cure. Pattern hair loss is an ongoing process, so any benefit usually needs maintenance sessions to sustain, and PRP is often used alongside, rather than instead of, established approaches. If hair is your main concern, it is worth reading our dedicated guides to PRP for hair loss and the wider range of hair-loss treatments offered at clinics.
What does the evidence actually say?
Here honesty is essential. PRP is a genuinely promising treatment, but the research base is still developing and has real limitations. Studies vary widely in how the plasma is prepared, how much is used, how often, and how results are measured — which makes it hard to compare trials or point to a single reliable figure. Reviews of the hair-loss literature have generally been cautiously positive while stressing that larger, better-standardised trials are needed; the skin-rejuvenation evidence is more mixed and earlier-stage.
The practical takeaway is not that PRP does not work, but that results are variable and not guaranteed, and no reputable clinic should promise a specific outcome. Be wary of any provider that offers before-and-after certainty or presents PRP as a miracle cure.
Who is it for — and who should avoid it?
PRP tends to suit people who want a natural-concept, low-downtime option, hold realistic expectations, and are willing to commit to a course of treatment plus maintenance. For skin, that means someone seeking an improvement in quality and texture rather than volume; for hair, someone with early-to-moderate thinning rather than long-established baldness.
It is not right for everyone. PRP is generally avoided or approached with caution in people with certain blood or platelet disorders, those taking blood-thinning medication, anyone with an active infection or skin condition in the treatment area, some chronic conditions or cancers, and during pregnancy or breastfeeding. Because the quality of your own blood matters to the result, factors such as smoking and some medications can also have an effect. A proper medical consultation is the only way to confirm whether it is appropriate for you — and a good practitioner will sometimes advise against it.
Sessions, downtime and results
PRP is typically delivered as an initial course rather than a single treatment — often around three sessions spaced roughly a month apart, followed by maintenance every several months, though protocols vary between clinics and individuals. Because a course is the norm, it makes sense to ask about the plan as a whole rather than judging by a single visit.
Downtime is usually modest. You can expect some redness, swelling, tenderness or bruising at the injection or microneedling sites for a few days, and the scalp or face may feel a little tight afterwards. Most people return to normal activities quickly. As with any treatment that works gradually, patience is part of the deal.
Safety and choosing a clinic well
Because PRP uses your own blood, the treatment itself is generally well tolerated, with side effects usually limited to temporary bruising, swelling and tenderness. The most important safety issues are about how, and by whom, it is done. Drawing blood, handling it and re-injecting it demands strict sterile technique and correct equipment; poor practice has, in rare cases, led to serious infections where hygiene standards were not met. This is a treatment where the training, medical background and hygiene standards of the provider genuinely matter.
In the UK, PRP prepared from your own blood is not regulated in the same way as a prescription medicine — which is all the more reason to check credentials yourself. Look for a suitably qualified, insured practitioner working in a clean, professional clinical setting, using proper equipment, who takes a full medical history, sets honest expectations and is happy to discuss the limits of the evidence. Combining PRP with other treatments such as microneedling should be a considered clinical decision, not an upsell.
Costs — a rough guide
Prices vary widely by clinic, the area treated and the number of sessions, so treat any figure as a broad guide rather than a quote. PRP is usually priced per session, and because a course is normally recommended, it is sensible to ask about the total cost of a full programme — including likely maintenance — rather than focusing on a single-session price. As with all aesthetic treatments, the cheapest option is rarely the right way to choose: the practitioner’s training and the clinic’s standards matter far more than the headline price.
Making an informed choice
PRP is one of the more intriguing tools in aesthetic medicine — a low-downtime, natural-concept treatment with real promise for skin quality and early hair thinning, held back by evidence that is still catching up with the marketing. Approached with realistic expectations and a good practitioner, it can be a reasonable option; approached as a miracle cure, it will disappoint.
If you are considering it, focus first on the clinic and the person holding the syringe. Use Clinic Finder to compare accredited clinics near you, check your practitioner’s credentials and training, and ask directly about their experience, their protocol and what results are realistic for you.
