Polynucleotides vs Profhilo vs Skin Boosters vs Biorevitalization
Laser hair removal is a popular method of removing unwanted body hair. It has become even more common in the last few years.
The aesthetic medicine landscape has undergone a major paradigm shift. While traditional dermal fillers remain popular for replacing structural volume loss, modern clinical practice increasingly emphasizes cellular repair, skin health, and natural rejuvenation.
Patients today are less interested in an overfilled appearance and far more focused on overall skin quality enhancement, elasticity, and luminous radiance. Navigating the spectrum of injectable moisturisers, biostimulators, and regenerative treatments can be challenging. Polynucleotides, Profhilo, traditional skin boosters, and classic biorevitalization cocktails all share the goal of revitalising tired skin, yet they operate through fundamentally distinct biological pathways.
Overview of Regenerative Injectable Options
Modern aesthetic medicine categorises skin-enhancing injectables into distinct biological classes. Traditional non-crosslinked stabilised hyaluronic acid formulas provide direct, moisture-binding properties to the extracellular matrix. However, the wider domain of regenerative injectables focuses on true cellular activation.
Beyond hyaluronic acid, advanced biostimulators such as poly-l-lactic acid (PLLA) and calcium hydroxylapatite (CaHA) create a controlled subclinical inflammatory response that triggers neocollagenesis to address structural degradation.
Alongside these, cellular therapies have advanced dramatically:
- Platelet Rich Plasma (PRP): Concentrates autologous growth factors to accelerate healing.
- Exosome Injections: Deliver paracrine signalling vesicles directly to fibroblasts.
- Systemic Coenzymes (e.g., NAD+): Increasingly paired with injectables to counter intrinsic biological senescence.
- DNA-Derived Bio-Revitalising Injectables (Polynucleotides): Bridge the gap between simple dermal hydration and deep physiological cellular repair.

How Each Treatment Works and Differs
Understanding the differences between these treatments requires examining their active compounds and histological targets.
| Treatment | Core Mechanism | Primary Physiological Target |
|---|---|---|
| Polynucleotides | DNA-derived bio-revitalising nucleotide chains | Fibroblast CD39/A2A receptors; cellular repair & DNA synthesis |
| Profhilo | Thermally stabilised, high- & low-molecular weight HA complexes | Intercellular bio-remodelling; elastin & collagen stimulation |
| Skin Boosters | Micro-droplets of lightly or non-crosslinked HA | Dermal hydration depot; water retention in mid-dermis |
| Biorevitalization | Uncrosslinked HA combined with amino acids, vitamins, minerals | Direct nutrient delivery; free radical scavenging via mesotherapy |
Treatable Areas
Injectable options vary significantly in rheology and tissue integration, which dictates their optimal anatomical placement:
Delicate Under-Eye Area
Presents an anatomical challenge due to ultra-thin skin and fragile lymphatic drainage. Hydrophilic hyaluronic acids can easily cause the Tyndall effect or persistent malar edema. Polynucleotides are the gold standard here, treating dark circles, hollows, and crepey tissue without attracting excess water.
Full Face & Cheeks
Profhilo is designed around Bio Aesthetic Points (BAP) across the malar regions and cheeks to maximise spread and contour integrity. Skin boosters can be distributed uniformly across the full face to correct diffuse micro-crepiness.
Jawline & Temples
Profhilo supports structural smoothing along the jawline, while thin-dermis zones such as the temples respond well to targeted polynucleotides or uncrosslinked biorevitalizers.
Neck & Chest
Fragile platysmal neck bands and photoaged skin of the décolletage are exceptionally well-suited to both Profhilo and polynucleotide protocols.
Backs of the Hands
Dorsal surfaces frequently display volume depletion and thin skin; all four modalities can be applied depending on specific tissue requirements.
Results and Effectiveness Comparison
Each injectable delivers distinct clinical outcomes based on its underlying biological mechanism:
Polynucleotides: Excel at treating compromised tissue architecture. They demonstrate exceptional efficacy in healing acne scarring, reversing elastosis in sun-damaged skin, and rebuilding thinning, reactive skin barriers. Patients notice gradual, structural skin quality enhancement over a progressive visible results timeline of 6 to 12 weeks.
Profhilo: Provides noticeable improvement in dermal laxity. Its primary strength is gentle skin tightening alongside profound skin hydration and elasticity. It softens fine lines and crepey skin while conferring a characteristic "lit-from-within" radiance across broad anatomical areas.
Skin Boosters: Deliver unmatched skin glow and radiance by creating deep hydration reservoirs. Patients see noticeable improvements in light reflection, elasticity, and micro-relief smoothing, making this an ideal option for dry, rough, or dull complexions.
Biorevitalization: Produces fast-acting improvements in overall tone and vitality, restoring dull, metabolically exhausted tissue, though it offers less prolonged mechanical tensile change.
For durable, long-term ageing outcomes, modern protocols increasingly pair these therapies together within comprehensive regenerative skincare regimens.
Number of Sessions Required
Optimal cellular stimulation requires dedicated loading and maintenance protocols rather than an isolated single session.
| Treatment | Primary Induction Protocol | Treatment Spacing | Recommended Maintenance |
|---|---|---|---|
| Polynucleotides | Course of 2–4 treatments | 2–4 weeks apart | Every 6–9 months |
| Profhilo | Initial course of 2 sessions (rarely 3) | Exactly 4 weeks apart | Maintenance every 4–6 months |
| Skin Boosters | Course of 2–3 sessions | 3–4 weeks apart | Every 6 months |
| Biorevitalization | Course of 3–5 sessions | 2 weeks apart | Every 3–4 months |
An initial consultation allows the clinician to assess baseline skin health, tissue thickness, and degree of photoaging. The number of treatments and their spacing between treatments are tailored accordingly. While Profhilo relies on a strict two-stage cycle to establish bio-remodelling, nucleotide therapies require sequential cycles to achieve best results, followed by ongoing maintenance depending on individual goals.
Downtime and Recovery
All four injectable options involve minimal downtime, allowing most patients to resume normal routines quickly. However, immediate post-procedural presentations differ:
Injection Marks
Profhilo is administered using the BAP technique (10 targeted boluses on the face), producing small, localized swelling deposits that resemble bee stings. These typically disperse within 12 to 24 hours as the product integrates into surrounding tissue.
Papules & Swelling
Traditional skin boosters, mesotherapy, and polynucleotides often rely on multi-point intradermal papular techniques. This can leave visible micro-blebs, mild swelling, and temporary redness for 24 to 72 hours, especially in vascular zones like the lower eyelids.
Bruising
Transient bruising is possible whenever the dermis is punctured, though typically minor and easily concealable after the initial healing period.
Tissue Safety
Because these formulations lack rigid cross-linked matrices, they carry a very low risk of vascular complications or permanent scarring. Patients with deep cellular depletion may experience prolonged erythema as local tissue repair mechanisms activate.
Cost Comparison
Treatment costs reflect manufacturing processes, molecular purity, and required session frequency:
| Modality & Area | Per Session | Full Course Protocol |
|---|---|---|
| Polynucleotides (Eye Area / Target Zone) | £250 – £350 | £700 – £900 Course of 3 |
| Polynucleotides (Full-Face Courses) | £350 – £500 | £950 – £1,350 Course of 3 |
| Profhilo (Standard 2ml Syringe) | £300 – £400 | £540 – £750 2 Sessions |
| Skin Boosters (Full Face) | £220 – £350 | £600 – £850 Course of 3 |
| Biorevitalization / Mesotherapy Cocktails | £135 – £250 | £365 – £600 Course of 3 |
Regional pricing reflects clinical expertise and geographic location. A single session of simple biorevitalization can start around £135, while entry-level courses sit around £365. A complete two-stage Profhilo package often begins near £540, and multi-session full-face nucleotide packages range upward based on the total volume required.
Combining Treatments
Modern aesthetics increasingly moves away from single-modality treatments in favor of synergistic protocols. Because each therapy targets distinct biological layers, combining them within a thoughtful treatment plan often delivers superior outcomes.
Multi-Layered Regenerative Framework
Profhilo / Skin Booster
Mid-to-lower face dermis: targeted for hydration and bio-remodelling.
Polynucleotides
Periorbital skin & scar zones: targeted for DNA repair and cellular renewal.
Microneedling / PRP
Epidermal surface: targeted for collagen induction and surface texture.
Zonal Combination
Pairs Profhilo across the mid and lower face for bio-remodelling with polynucleotides restricted to the fragile periorbital skin. This delivers deep hydration while safely rejuvenating thin tear troughs without water retention.
Layered Regeneration
Preparing photoaged skin with polynucleotides stimulates dormant fibroblasts and repairs microvascular foundations. Following this with hyaluronic acid skin boosters four weeks later ensures the cellular matrix effectively holds structural water.
Adjunctive Protocols
Combining treatments with microneedling or exosome therapy enhances the skin's reception to topically delivered bio-signals, boosting overall rejuvenation.
Which Treatment Is Right for You?
Selecting the appropriate injectable depends on primary skin concerns, tissue quality, anatomical areas, and broader treatment goals:
Choose Polynucleotides if:
You want to address hollow, dark circles around the eyes, treat underlying acne scarring, or heal thin, sun-damaged skin. It is the leading regenerative approach for biological renewal rather than simple volume addition.
Choose Profhilo if:
Your main concern is mild to moderate skin laxity across the face, neck, or décolletage. It suits individuals needing broad dermal smoothing, enhanced elasticity, and an all-over lifting glow without altering facial contours.
Choose Skin Boosters if:
Your skin is chronically dehydrated, dull, or displays uniform micro-crepiness across the cheeks and mouth area. It provides a long-lasting internal moisture reservoir that restores radiance.
Choose Biorevitalization if:
You are younger or preparing for a major event, and need to refresh tired skin suffering from acute environmental stress, smoking, or post-travel fatigue.
