PRF and 'EZ Gel'
Platelet-rich fibrin · heated plasma gel 'natural filler'
'EZ Gel' and 'bio-filler' have spread through US injector Instagram and beauty newsletters as the 'natural filler' for people who have dissolved their hyaluronic acid and want something autologous for the under-eye.
It is a biostimulant with a few months of soft volume; treated as that, it has a place after dissolving, before the next decision.

Does PRF and 'EZ Gel' work?
Promising. It is a biostimulant with a few months of soft volume; treated as that, it has a place after dissolving, before the next decision. Systematic reviews of PRP and PRF for facial rejuvenation find small studies with improvement in skin thickness and elasticity more often than in wrinkles or pigmentation, and no serious adverse events.
- Verdict
- Promising Plausible mechanism and early evidence. Reasonable to try with realistic expectations.
- Evidence base
- 4 PubMed-indexed studies cited below, including systematic reviews.
- Suits
- Thin, crepey under-eye skin or fine lines in people who want an autologous option and accept a short-lived, modest result with repeat sessions.
- Not for
- True hollows or bags, anyone expecting the longevity of hyaluronic acid, and anyone sold it as a 'natural facelift'.
- In Singapore
- Autologous blood products are prepared and injected by doctors in licensed clinics in Singapore.

What it is
Platelet-rich fibrin is blood spun without anticoagulant so it forms a soft fibrin clot or liquid that releases growth factors slowly. 'EZ Gel' and similar heat the platelet-poor plasma to denature albumin into a gel, then mix it with liquid PRF to make a thicker, longer-lasting injectable. It is sold as a filler; it behaves as a short-lived volumiser and a biostimulant.
How it works
Fibrin traps platelets and leukocytes and releases growth factors over days rather than minutes, which is the proposed advantage over PRP. Heating plasma turns albumin into a gel that holds shape for weeks to a few months before being resorbed. Any volume effect is temporary; any lasting benefit is collagen stimulation, which is modest. Preparation varies with every centrifuge, tube and heating protocol.
What the evidence says
Systematic reviews of PRP and PRF for facial rejuvenation find small studies with improvement in skin thickness and elasticity more often than in wrinkles or pigmentation, and no serious adverse events. A 2025 systematic review of periorbital treatment found PRF improved texture and crepiness while its effect often faded by six months. The heated albumin gel has biocompatibility and degradation data in animals and dental use, and clinical series for the face, but no controlled trials against hyaluronic acid filler or against PRF alone. Marketing has run well ahead of the data.

What the studies show
- systematic review
Twenty studies in 514 patients reported significant improvement most often for skin thickness and elasticity, less often for wrinkles and texture, and not for hydration, with no serious adverse events.
Systematic Review of Platelet-Rich Plasma and Platelet-Rich Fibrin in Facial Rejuvenation — Annals of Plastic Surgery, 2025. PMID 40167104.
- systematic review
Across fourteen studies PRF improved periorbital texture and crepiness while PRP had stronger evidence for pigmentation; PRF improvements often diminished by six months.

- cohort
Heat-denatured albumin combined with liquid PRF was biocompatible and degraded over months in an animal model, the basis for the heated plasma gel products.

Alternatives
The two reviewed treatments most often weighed against PRF and 'EZ Gel', on the same standard.
| PRF and 'EZ Gel' | Pico laser | PDRN and polynucleotides | |
|---|---|---|---|
| Verdict | Promising | Vetted | Established |
| What it is | Platelet-rich fibrin is blood spun without anticoagulant so it forms a soft fibrin clot or liquid that releases growth factors slowly. | A picosecond laser delivers energy in pulses a thousand times shorter than the nanosecond lasers that came before it. | Polynucleotides are DNA fragments, usually purified from salmon or trout gonads, injected into the dermis in micro-droplets. |
| Evidence base | 4 PubMed-indexed studies cited below, including systematic reviews. | 4 PubMed-indexed studies cited below, including systematic reviews. | 3 PubMed-indexed studies cited below, including systematic reviews, randomised trials. |
| Suits | Thin, crepey under-eye skin or fine lines in people who want an autologous option and accept a short-lived, modest result with repeat sessions. | Sun spots, freckles, post-acne marks, tattoo ink, uneven tone in Asian skin when energy is set conservatively. | Thin, crepey under-eye skin; dull, inflamed or acne-prone skin; post-procedure recovery; people who want quality rather than volume. |
| In one line | It is a biostimulant with a few months of soft volume; treated as that, it has a place after dissolving, before the next decision. | The variable that matters is depth, not brightness, and pigment already deposited is only half the problem; the inflammation producing it is the other half. | The injected courses are a sensible part of a skin plan; the salmon-sperm facial is mostly the microneedling doing the work. |
Risks
Bruising, lumps and swelling for days, infection if blood handling is poor, and disappointment when the gel resorbs. Vascular risk is lower than with cross-linked filler but not zero.
In Singapore
Autologous blood products are prepared and injected by doctors in licensed clinics in Singapore. Confirm the centrifuge and tube system's HSA registration with the provider; heated plasma gel preparations are an off-label modification.
