PRP and PRF facial treatments use a patient’s own blood to prepare a platelet-containing product for injection or procedural use. Platelet-rich plasma (PRP) generally uses an anticoagulant and centrifugation; platelet-rich fibrin (PRF) uses different processing intended to create a fibrin-rich preparation. Concentrations, white-cell content, activation, equipment, and final product vary widely.
Route matters
Direct intradermal injection, application after microneedling, and combination with laser are different procedures. Evidence from one route or preparation cannot automatically support another. A clinic should document the collection kit, centrifuge protocol, final volume, injection or application route, and every added ingredient.
Evidence
Small trials and reviews report possible improvement in selected texture, fine-line, or acne-scar measures, but methods and outcomes are heterogeneous. There is no standardized aesthetic PRP or PRF dose, and results are usually subtle. PRP should not be described as stem-cell therapy.
Blood handling and microneedling
Autologous does not mean risk-free. Correct patient identification, sterile collection, closed processing, surface disinfection, sharps safety, and single-patient supplies are essential. Microneedling devices are not broadly cleared as delivery systems for cosmetics, drugs, or biologics; the clinic should explain the regulatory and evidence basis for any combination.
