The Rationale for Combined Treatment: Two Different Mechanisms, One Goal
Filler and PRP work through two complementary biological mechanisms in the facial rejuvenation process. To understand these two treatments together, it is necessary first to clarify clearly what each one does:
| Property | Hyaluronic Acid Filler | PRP (Platelet-Rich Plasma) |
|---|---|---|
| Onset of effect | Immediate | Within 4–8 weeks |
| Primary effect | Volume + contour correction | Collagen synthesis + skin quality + hydration |
| Longevity | 6–18 months (by area) | 12–18 months (tissue renewal) |
| Source? | Synthetic / biotechnological production | From the patient's own blood |
| Reversible? | Yes (with hyaluronidase) | Yes (naturally through biological process) |
What Is PRP? How Do Growth Factors Work?
PRP (Platelet-Rich Plasma) is obtained by centrifuging the patient's own blood to increase the concentration of platelets. When these platelets are activated, they release growth factors:
- PDGF (Platelet-Derived Growth Factor): Stimulates fibroblasts to initiate collagen synthesis
- TGF-β (Transforming Growth Factor-beta): Regulates tissue renewal and cell migration
- VEGF (Vascular Endothelial Growth Factor): Promotes new blood vessel formation (angiogenesis)
- EGF (Epidermal Growth Factor): Accelerates epidermal cell renewal
- IGF-1 (Insulin-like Growth Factor): Supports hyaluronic acid synthesis
The combination of these factors directs the skin to repair itself: collagen increases, skin thickens, pores shrink, and moisture balance improves.
Can They Be Applied in the Same Session? Scientific Basis
Yes, filler and PRP can be safely applied in the same session. The scientific rationale for this combination is as follows:
HA filler initiates a mild inflammatory response at the injection site, which increases local vascularisation. The growth factors in PRP are better absorbed in this enriched vascular environment and are activated more quickly. In other words, the local environment created by filler may enhance the effectiveness of PRP.
Additionally, clinical observations suggest that PRP supports the stability of HA within tissue: the growth factors in PRP can partially inhibit hyaluronidase activity, potentially extending filler longevity — although this effect has not yet been fully proven by large randomised trials.
Technical Order: Filler First or PRP First?
The order of application in a combination session matters. The protocol adopted at Virtuana Clinic is as follows:
- Blood draw and PRP preparation: The patient's blood is drawn at the start of the session and the centrifuge process begins (15–20 minutes). This time coincides with the preparation required for filler.
- Topical anaesthesia: Anaesthetic cream is applied for both procedures.
- Filler application: HA filler is administered first. The reason: filler defines the tissue planes; a clean anatomical map is important before applying PRP. Additionally, oedema caused by filler should not influence the PRP decision.
- PRP application: Immediately after the filler session, the prepared PRP is applied by micro-injection or mesotherapy technique. Superficial and intradermal placement is preferred.
- Area cooling and aftercare instructions: A combined post-procedure protocol applicable to both treatments is followed.
Why filler first? Filler application shapes the area as the physician planned; PRP then nurtures this shaped tissue. If the order is reversed, the temporary oedema caused by PRP can make it difficult to assess whether filler has been applied in the right amount.
The Concept of PRP "Nourishing" the Filler
This concept, frequently used in clinical practice, expresses scientific reality in plain language. The growth factors in PRP:
- Improve the quality of the tissue surrounding the filler, making the result look more natural
- Strengthen the foundation on which the filler sits through increased collagen and elastin
- May contribute to the filler remaining stable for longer by improving local circulation
- Speed up post-procedure healing: the duration of bruising and swelling is reduced
For this reason, the combination improves both immediate and long-term result quality compared to filler alone.
Ideal Candidate Profile
Filler + PRP combination is not recommended for every patient; the profile for whom the highest benefit is obtained is as follows:
- Age range: 35–55 (the period in which both volume loss and skin quality deterioration are seen together)
- Combination of concerns: Cheek sagging + skin dullness; under-eye hollowing + fine lines; nasolabial folds + general skin thinning
- Single-concern patients: If only volume loss is present, filler alone is sufficient; if only skin quality is the concern, PRP can be applied alone. The combination offers maximum value in cases where both concerns coexist.
- General health: PRP is contraindicated in active infection, active cancer treatment, platelet dysfunction or use of blood-thinning medication.
Session and Repeat Protocol
| Session | Content | Timing |
|---|---|---|
| Session 1 | Filler (full dose) + PRP (face) | Initial |
| Session 2 | PRP repeat (filler maintenance assessment) | 4–6 weeks later |
| Session 3 | PRP repeat | 4–6 weeks after session 2 |
| Annual maintenance | Filler maintenance dose + PRP repeat | Every 6–12 months |
Clinical Study Findings
Several clinical studies published between 2022 and 2024 support the synergistic effect of the HA filler + PRP combination:
- A study published in the Journal of Cosmetic Dermatology (2023) compared skin quality scores at 12 months between a control group receiving filler only and a group receiving filler + PRP; TEWL (transepidermal water loss) was significantly lower in the combination group.
- The Italian Society of Dermatology (SIDeMaST) 2024 guidelines described combining HA filler with PRP in facial rejuvenation protocols for middle-aged patients as a "safe and evidence-supported" approach.
- Clinical observational studies indicate that PRP reduces bruising and swelling during the post-filler recovery process by approximately 30–40% on average.
Virtuana Clinic: Combination Treatment Protocol
At Virtuana Clinic, the filler + PRP combination is carried out through the following steps:
- Detailed facial analysis and photographic documentation (pre-consultation)
- Patient history: platelet function, blood thinners, active infection check
- Blood draw + filler planning in the same session
- Filler first, then PRP application
- Post-session cooling, aftercare instructions and 48-hour WhatsApp follow-up
- Follow-up consultation 4–6 weeks later and decision on PRP session 2
