Profhilo and biorevitalizer guide: injectable skin hydration and remodeling

Profhilo (IBSA Farmaceutici) is an injectable skin biorevitalizer consisting of ultra-pure, stabilized hyaluronic acid — distinct from both cross-linked dermal fillers and traditional mesotherapy products. It is positioned as the highest-concentration injectable HA on the market for skin quality improvement and is the most extensively studied product in the "skin booster" category. Here is a complete guide to how it works and what to expect.

What Profhilo is — and what it is not

The HA spectrum in aesthetics

Hyaluronic acid in aesthetic medicine exists on a spectrum based on cross-linking:

Cross-linked HA (dermal fillers — Juvederm, Restylane, Sculptra HA):
HA chains are chemically cross-linked with BDDE (1,4-butanediol diglycidyl ether), creating a gel
High viscosity; stays in place after injection
Volumizes, lifts, and fills — appropriate for nasolabial folds, cheeks, lips, tear trough
Does not flow through tissue

Non-cross-linked HA (standard mesotherapy HA):
Low molecular weight HA in sterile water for injection
Very low viscosity; distributes through injection zone
Provides hydration; less structural support
Lower concentration products (typically 0.5–2% HA)

Profhilo — BDDE-free hybrid cooperative complex:
Ultra-high concentration HA (64 mg in 2 mL; 32 mg/mL) — among the highest injectable HA concentrations available
No chemical cross-linking (BDDE-free): Instead of BDDE cross-linking, Profhilo uses thermal cross-linking — a manufacturing process that creates a stable, cohesive HA complex through physical bonds rather than chemical cross-linkers
The product contains two molecular weights of HA in cooperative complex:
H-HA (high molecular weight HA): ~1,100 kDa — provides structural hydration and the "scaffold" that stays in the tissue slightly longer; associated with collagen type I and IV stimulation
L-HA (low molecular weight HA): ~80 kDa — diffuses more rapidly through the dermis; associated with elastin stimulation and fibroblast activation

This combination is called a Hybrid Cooperative Complex (HCC) — the two molecular weights work synergistically in a way neither alone would achieve.

The mechanism: hydration + remodeling

How Profhilo works differently from filler

Fillers volumize: Cross-linked HA occupies space and physically lifts tissue.

Profhilo remodels: The high-concentration, non-cross-linked HCC HA diffuses through the dermis after injection, providing:

Hygroscopic hydration: HA binds approximately 1,000 mL of water per gram — the highest-concentration injectable HA produces a dramatic increase in dermal hydration, restoring the water-binding capacity that diminishes with aging and UV damage

Fibroblast stimulation: HA fragments (particularly L-HA fragments) bind CD44 receptors on fibroblasts → fibroblast activation → increased production of:
Collagen types I and III
Elastin
Hyaluronic acid (stimulates endogenous HA production)

Tissue remodeling over time: The degradation products of injected HA continue to signal fibroblast activity as the HA is enzymatically broken down over 4–8 weeks

The result: Profhilo does not fill or volumize — it improves skin quality — hydration, elasticity, radiance, and fine line depth — through genuine tissue remodeling rather than mechanical volume addition.

The BAP injection technique

Why a specific technique exists

Standard mesotherapy injects 0.05–0.1 mL per point at multiple sites. Profhilo's high HA concentration and flow characteristics are optimized for a specific protocol: BAP (Bio Aesthetic Points) — 5 anatomically defined injection points per side of the face, delivering 0.2 mL per point.

The five BAP points (per side, 10 total for the face)

The BAP points are anatomically mapped to:
Cheekbone point (zygomatic) — upper lateral cheek; the HA diffuses broadly from this superficial fat compartment
Pre-parotid point — mid-lateral cheek; provides coverage of the lower cheek and lateral face
Chin point — the mentum; diffuses across the lower face
Above mandible point — inferior cheek, above the jawline
Nasolabial point — medial cheek, along the nasolabial fold

Why BAP: The 5-point technique maximizes tissue diffusion coverage with minimal injection points. Each bolus of 0.2 mL at a BAP site diffuses to cover a 4–5 cm radius — the five points provide complete facial coverage without the 50+ injections of traditional mesotherapy.

Safety: The BAP points are mapped to avoid major vessels, parotid ducts, and facial nerve branches. Standard caution applies — aspiration where appropriate, knowledge of facial anatomy.

Clinical evidence

*Sparavigna et al. (2015, Dermatology and Therapy):* The key Profhilo registration study — 20 subjects receiving two Profhilo sessions 4 weeks apart. Significant improvements at 2 months:
Skin hydration: +21.7% (corneometry)
Skin elasticity: significant improvement (cutometry)
Dermis thickness: significant increase (ultrasound)
90% subject satisfaction

*Camenisch and Gruber (2017, Journal of Drugs in Dermatology):* Multi-center observational study (144 patients); significant improvement in skin laxity, hydration, and texture scores across all facial zones; improvement at 1, 2, and 4 months.

Independent comparison data: Profhilo generally outperforms standard non-cross-linked mesotherapy HA products in hydration and elasticity endpoints — attributed to the higher HA concentration and dual molecular weight mechanism.

Treatment protocol

Standard protocol: Two sessions, 4 weeks apart (the "on-face" protocol). Results begin within 2–3 weeks of the first session; full results assessed 4 weeks after the second session.

Maintenance: Single session every 6 months to maintain results. The collagen and elastin remodeling effect persists beyond the HA degradation period — benefit is not purely from HA presence.

Treatment experience:
10 injections (5 per side) using a fine-gauge needle (27–30 gauge)
Mild discomfort at injection points; 2–4/10; topical anesthetic optional
Immediate small boluses visible under skin at injection points; flatten within 1–2 hours
No significant downtime; mild erythema and occasional bruising resolve within 24–48 hours

Realistic expectations

What Profhilo does:
Significantly improves skin hydration and translucency
Improves fine line depth and surface texture
Improves skin elasticity and "bounce"
The result is a "better version of your own skin" — not volume, not lifting, not structural change

What Profhilo does not do:
Fill or volumize (nasolabial folds, cheeks, lips require cross-linked filler)
Address significant laxity or jowling (requires RF, HIFU, or surgery)
Replace a retinoid for collagen induction (different mechanism, complementary)

Who benefits most: Patients 30–55 with dull, dehydrated, or mildly lax skin who want genuine skin quality improvement without the volumizing effect of filler. Particularly popular as a "skin health" treatment distinct from sculpting or anti-aging procedures.
