It has been called the vampire facial. Athletes have used it to recover from injuries. Celebrities have credited it for glowing skin and thicker hair. Platelet-rich plasma therapy, better known as PRP, has moved firmly from the fringes of medicine into mainstream wellness conversations — and in South Africa, where aesthetic treatments and regenerative health are a growing focus, interest is only building. But what is it actually, does it work, and is it worth considering?
The basics: what PRP therapy involves
PRP is a regenerative medicine technique that uses your own blood as the treatment. A small amount of blood is drawn, placed in a centrifuge to separate its components, and the resulting plasma — now concentrated with platelets and growth factors — is injected back into a targeted area of the body. The idea is to amplify the body’s own natural healing response. Platelets are what the body deploys when tissue is damaged: they form clots, release growth factors, and trigger the repair process. PRP essentially delivers a concentrated dose of that healing capacity directly where it is needed.
What it is used for
The therapy has found application across several areas of medicine and aesthetics, with varying levels of evidence behind each.
Joint and muscle injuries are among the more established uses. Research has shown meaningful results for conditions like knee osteoarthritis, with patients reporting reduced pain and improved daily functioning. Tendon injuries, sports-related strains and certain hip and ankle conditions have also shown promise in clinical reviews, with a 2023 paper describing PRP as showing “clear evidence of safety” across a range of musculoskeletal problems.
Hair restoration is another area where the research is relatively strong. A recent meta-analysis found that PRP therapy can significantly improve hair density and thickness, making it a growing option for women experiencing thinning or loss. Results depend heavily on the clinic, the equipment used, and the volume of blood drawn — factors that vary considerably between providers.
Skin rejuvenation, particularly when combined with microneedling in what has become known as the vampire facial, is popular in aesthetic medicine. The combination can stimulate collagen production and reduce recovery time after treatment. The evidence here is more mixed, with some studies showing clear benefit and others finding little difference compared to a placebo — but interest continues to grow as patients move away from synthetic fillers towards treatments they perceive as more natural.
PRP has also been explored in fertility medicine, with some clinicians suggesting it may support egg quality or uterine lining thickness in IVF patients. However, experts in reproductive endocrinology are cautious, noting that the evidence remains insufficient to draw any firm conclusions.
What to be realistic about
PRP is not a guaranteed fix, and results are genuinely variable. The quality of the treatment depends significantly on who is administering it, what equipment is being used, how the blood is processed, and the individual’s own health. Someone with a platelet disorder or who is undergoing cancer treatment may not be a suitable candidate at all.
The therapy also requires patience. Effects can take weeks or months to materialise, and a single session is often not enough, particularly for aesthetic goals. It is almost always most effective when used alongside other treatments — physiotherapy for injuries, topical treatments for hair loss, or nutritional support for chronic pain — rather than as a standalone solution.
Pain during injection is also worth factoring in. Depending on the area being treated, the procedure can range from uncomfortable to significantly painful, and patients should discuss pain management with their provider beforehand.
Choosing a provider carefully
With PRP growing in popularity, it has inevitably spread beyond specialist medical settings into spas and wellness centres, where the standards of practice vary enormously. The quality of the plasma produced, the volume of blood drawn, and the precision of the injection all affect outcomes. Seeking a qualified, board-certified practitioner in a proper medical setting — rather than shopping on price alone — is essential for anyone considering the treatment.
PRP holds genuine promise, particularly in orthopaedics and hair restoration. But it remains a field still building its evidence base, and anyone exploring it should do so with clear expectations, a thorough medical consultation, and a provider they can trust.
