PRP vs PRF in Aesthetics: Key Differences in Preparation and Clinical Use
PRP and PRF are both autologous blood-derived treatments, but differ in preparation method, growth factor concentration, and clinical applications—here's what medspa owners need to know.
PRP (Platelet-Rich Plasma) and PRF (Platelet-Rich Fibrin) are both autologous treatments derived from a patient's own blood, but they differ fundamentally in how they're prepared and how they perform clinically.
Preparation: The Core Difference
PRP uses a centrifuge to separate blood components by density, then applies an anticoagulant (usually sodium citrate) to prevent clotting. The result is a liquid suspension rich in platelets and growth factors.
PRF uses a different centrifugation protocol—typically a slower spin at lower G-force—without anticoagulant. This allows the blood to clot naturally during the spin, trapping platelets and white blood cells in a fibrin matrix. The result is a gel-like or solid product.
The key: PRF's fibrin scaffold releases growth factors more slowly and steadily over time, while PRP delivers a more immediate but shorter-lived boost.
Clinical Applications
Hair Loss
Both are used for androgenetic alopecia, though evidence remains mixed. PRP has more published studies showing modest improvement in hair density and thickness. PRF's slower release may theoretically offer sustained benefit, but head-to-head trials are limited. Many practices offer both and let patient preference and budget guide choice.

Patients seeking faster results
Patients seeking longer-acting, sustained support
Bottom line: Choose PRP for immediate results and established evidence; choose PRF for patients preferring a longer-acting profile—both require careful informed consent and state-specific regulatory verification.
PRF's fibrin scaffold releases growth factors slowly over time, while PRP delivers a more immediate but shorter-lived boost.
Under-Eye and Periorbital Rejuvenation
PRP is more established here, with practitioners using it for tear trough hollowing, fine lines, and skin texture. The immediate growth factor surge can stimulate collagen and improve skin quality.
PRF is gaining traction for the same indications, with some practitioners preferring its longer-acting profile for sustained results. The fibrin matrix may also provide structural support.
Evidence and Realistic Expectations
Both treatments are not FDA-cleared as drugs—they're considered autologous cell therapies or biologics, regulated differently by state boards. Evidence is growing but remains modest compared to injectables or lasers. Results vary widely by patient, technique, and product quality.
For practice owners: Verify your state's specific regulations on preparation and marketing claims. Document informed consent carefully, as both are considered off-label for most aesthetic uses. Consider offering both if your patient base values options—PRP for faster results, PRF for those seeking longer-acting support.
Neither replaces proven treatments, but both can complement a comprehensive aesthetic menu.
Frequently asked questions
What's the difference between PRP and PRF preparation?
PRP uses centrifugation with anticoagulant (sodium citrate) to create a liquid platelet suspension, while PRF uses slower centrifugation without anticoagulant, allowing natural clotting that traps platelets and white blood cells in a fibrin matrix. This makes PRF gel-like or solid, while PRP remains liquid.
Does PRP or PRF work better for hair loss?
PRP has more published studies showing modest improvement in hair density and thickness for androgenetic alopecia. PRF's slower growth factor release may theoretically offer sustained benefit, but head-to-head trials are limited, so many practices offer both and let patient preference guide the choice.
How long do PRP and PRF results last?
PRP delivers a more immediate but shorter-lived growth factor boost, while PRF's fibrin scaffold releases growth factors more slowly and steadily over time, potentially providing longer-acting support. The exact duration varies by patient, technique, and product quality.
Is PRP or PRF FDA-approved for cosmetic use?
Neither PRP nor PRF is FDA-cleared as drugs—they're regulated as autologous cell therapies or biologics under state board oversight. Both are considered off-label for most aesthetic uses, so practices must verify state-specific regulations and document informed consent carefully.
Which is better for under-eye rejuvenation, PRP or PRF?
PRP is more established for tear trough hollowing and fine lines, with the immediate growth factor surge stimulating collagen and improving skin quality. PRF is gaining traction for the same uses, with some practitioners preferring its longer-acting profile and the structural support the fibrin matrix may provide.
