A vampire facial is microneedling. The PRP is an extra step on top of it. Blood is drawn, spun in a centrifuge to concentrate the platelets, and that platelet-rich plasma is applied to skin that has just been microneedled, so the open channels carry it in. It may also be injected.
So this is not a choice between two treatments. It is a choice about whether to add PRP to a treatment you are already having. The honest framing is "microneedling, with or without PRP".
The evidence for the added benefit is thin and mixed. In a meta-analysis of scar treatments, PRP on its own gave a 23% overall response, about the same as laser (22%) or microneedling (23%); added to microneedling, 43% had a marked and 23% an excellent response. But a network meta-analysis of 24 randomised trials and 1,546 people ranked microneedling with a chemical peel above microneedling with PRP on improvement, satisfaction and efficacy.
And PRP has no FDA authorisation for any aesthetic use. The kits that prepare it are cleared, but for preparing PRP to mix with bone graft in orthopaedic surgery. Aesthetic PRP is off-label practice of medicine — which is legal, but it is not what "FDA approved" means.
Blood is drawn, spun in a centrifuge, and the platelet-rich fraction separated from red cells and the platelet-poor layer.
Platelets carry a set of signalling proteins — the growth factors the body uses to direct repair. The theory is that concentrating and re-delivering them speeds up healing.
Fine needles create thousands of vertical channels; healing brings fibroblast activity, new collagen and elastin remodelling.
PRP preparation devices are cleared, reviewed as biologics, for preparing PRP to be mixed with bone graft at an orthopaedic surgical site. That is the cleared purpose.
SkinPen Precision was authorised in March 2018 (De Novo DEN160029) for facial acne scars in adults 22 and over; the neck indication followed in 2021. Dermapen 4 is cleared for facial acne scars in Fitzpatrick I–V.
The added benefit is the disputed part, not the microneedling underneath it.
It does not tighten lax skin and has no effect on fat.
Platelets are the cell fragments that plug a wound. They contain granules loaded with growth factors — the signalling proteins the body uses to direct repair. PRP concentrates them from your own blood and puts them back into skin that has just been wounded on purpose.
The biology is plausible. The problem is the product: there is no standard for what "PRP" contains. A published review of clinic data showed FDA-cleared devices turning out PRP of inconsistent composition. Two clinics can both offer "PRP" and be delivering meaningfully different things.
The most useful summary is that the increment is smaller than the marketing suggests.
This procedure involves drawing blood, handling it, and putting it back into open wounds. That makes basic infection control non-negotiable.
In 2024 the CDC reported an investigation in MMWR into presumptive HIV transmission among former clients of a New Mexico spa offering PRP microneedling facials. Four former clients and one sexual partner of a client were diagnosed with HIV between 2018 and 2023 despite low reported risk, and genetic sequencing showed highly similar virus strains across the cases. The facility was unlicensed, did not follow recommended infection control procedures, and kept no client records, which made tracing and notifying other clients much harder.
The lesson is not that PRP causes HIV. It is that any procedure combining blood handling with needles has to happen in a licensed facility, with sterile single-use equipment and proper records. Ask where the blood is spun, who is doing it, and whether the facility is licensed. A clinic that cannot answer clearly is the risk — not the biology of PRP.
A 2025 systematic review found 15 published cases of granulomatous reactions after microneedling — firm inflammatory lumps, most often linked to motorised microneedling pens and topical vitamin C applied to freshly treated skin. Improvement was inconsistent across steroids, antibiotics and systemic anti-inflammatories, so some cases proved stubborn.
Those cases involved topical products, not PRP. The transferable point is that a microneedled face is not normal skin, and whatever is put onto it is going somewhere a serum never reaches.
