Biofillers with PRF: Fillers with Platelet-Rich Fibrin for Regeneration and Volumization

Biofillers: A Category of Fillers That Changes the Rules

Aesthetic medicine has worked for years with two distinct categories: fillers (hyaluronic acid, Radiesse) that add volume, and biostimulators (Sculptra, PRP) that stimulate tissue regeneration. Biofillers with PRF (Platelet-Rich Fibrin) break this dichotomy: they are biological fillers that simultaneously offer a volumizing effect and powerful tissue regeneration, using only the patient's own plasma.

What is PRF and why is it different from PRP

Many patients are familiar with PRP (Platelet-Rich Plasma), used for years in aesthetic medicine to treat hair loss, facial rejuvenation, and tissue repair. PRF (Platelet-Rich Fibrin) is an evolution of that same concept with important differences:

| | PRP | PRF |

|---|---|---|

| Anticoagulant | Yes (added to prevent coagulation) | No (completely natural process) |

| Fibrin network | Absent or destroyed | Intact — forms a three-dimensional matrix |

| Leukocytes | Variable | High concentration (leukocytes modulate inflammation and regeneration) |

| Growth factors | Released all at once when platelets are activated | Released slowly from the fibrin network (days-weeks) |

| Consistency | Liquid | Can be obtained in liquid or solid (membrane) form |

| Filling effect | No | Yes, in concentrated liquid form |

The PRF fibrin network is key: it acts as a biological scaffold that retains platelets and leukocytes in the tissue, and gradually releases growth factors over days and weeks, instead of all at once. The regenerative effect is more sustained and deeper.

How biofillers with PRF are prepared

1. Blood extraction: 2-4 tubes without anticoagulant
2. Immediate centrifugation: timing is critical — the fibrin polymerization process begins immediately and the working window is only a few minutes
3. PRF separation: the fibrin fraction rich in platelets and leukocytes is obtained
4. Biofiller preparation: liquid PRF (before its complete polymerization) can be used directly as an injectable, or combined with plasma gel to increase its viscosity and volumizing effect

The resulting product is a 100% autologous biological gel, rich in growth factors (VEGF, PDGF, TGF-β, IGF-1), with physical properties that allow its injection into areas of volume loss.

What biofillers with PRF do in the tissue

Once injected:

Immediate mechanical action

The gel occupies the space and visibly restores volume. The correction is immediate, although the gel eventually reabsorbs as the fibrin degrades.

Prolonged regenerative action

Fibrin retains growth factors in the tissue and progressively releases them over 2-4 weeks:

• VEGF: stimulates the formation of new vessels (better tissue nutrition)
• PDGF: activates fibroblasts to produce collagen and elastin
• TGF-β: regulates collagen synthesis and modulates the inflammatory response
• IGF-1: stimulates the proliferation of connective tissue cells

The concentrated leukocytes in PRF also modulate inflammation during the regeneration process, promoting a clean and effective biological response.

The result: the treated tissue not only recovers volume — its structural quality improves over time.

Indications at Santé Clínica Estética

Biofillers with PRF are especially indicated for:

• Nasolabial folds and marionette lines that are deep and have a component of tissue quality loss
• Periocular rejuvenation (dark circles, lower eyelid) — an especially delicate area where PRF offers greater safety than synthetic fillers
• Malar volume restoration in patients who prefer a 100% autologous solution
• Improvement of skin quality in areas of actinic damage or chronological aging
• Neck and hands: areas with thin skin where tolerance to synthetic fillers is lower
• Patients with allergies or sensitivity to synthetic products
• Post-treatment complement (post-laser, post-peeling) to accelerate regeneration

The procedure at Santé

The session lasts between 60 and 90 minutes:

1. Blood extraction (10 min)
2. Centrifugation and PRF preparation (15-20 min) — preparation begins immediately
3. Topical anesthesia in treatment areas (30 min)
4. Injection of the biofiller with cannula or fine needle technique depending on the area (15-30 min)

The exact protocol (number of tubes, injection technique, areas to be treated) is defined by the doctor during the prior consultation.

Post-treatment

PRF, being biological, has a recovery profile similar to plasma gel:

• Edema and bruising in 48-72 hours (normal and expected)
• No significant activity restrictions
• Daily photoprotection recommended

Follow-up and results

• Immediate: visible volumizing effect
• 2-4 weeks: improved tissue texture and hydration
• 2-4 months: dermal densification and improved firmness
• Duration: variable, usually between 6 and 12 months for the volumizing effect; the regenerative effect (improved tissue quality) can be more lasting

Santé and autologous biofillers: our philosophy

At Santé, we believe that the best filler material is that produced by the body itself. Biofillers with PRF are an expression of this philosophy: instead of introducing external materials, we harness the patient's natural regenerative capacity, concentrated and applied with medical precision.

It is not the most suitable treatment for all cases — there are situations where hyaluronic acid or synthetic biostimulators are the best option. But when the goal is to combine volumization with regeneration in the most natural way possible, biofillers with PRF are hard to beat.

Frequently Asked Questions

How long does the volumizing effect last?

Between 6 and 12 months depending on the area and individual response. Less than standard hyaluronic acid, but the regenerative effect compensates with improvements in tissue quality.

Is it reversible?

Not directly. Being autologous, there is no enzyme that dissolves it. The gel degrades naturally, but it cannot be removed in case of an undesired result. Correct technique and indication are fundamental.

Can I combine PRF with hyaluronic acid?

At Santé, we can design combined protocols where PRF acts in the dermis as a biostimulator and hyaluronic acid in areas requiring more specific filling. They are compatible when applied in different planes.

How many sessions do I need?

For initial correction: 2-3 sessions spaced 4-6 weeks apart. Maintenance: annually or as evolution dictates.
