Similarities Between Treatments
Despite their differences, Profhilo and polynucleotides share important common ground. Both are injectable aesthetic treatments that aim to improve skin quality, stimulate natural biological processes, and deliver natural-looking results without altering facial structure or adding volume. Neither is classified as a traditional dermal filler, and both are typically well-tolerated with minimal downtime.
What Is Profhilo?
Profhilo is an injectable treatment containing one of the highest concentrations of hyaluronic acid available in any licensed aesthetic product. Unlike conventional dermal fillers, it is not designed to add volume or project tissue. Instead, Profhilo focuses on improving skin hydration, firmness, and elasticity by spreading evenly beneath the skin and triggering a biological remodelling response.
How Profhilo Works
Profhilo delivers stabilised hyaluronic acid that disperses across a wide area beneath the skin rather than remaining localised at the injection point. This distribution stimulates collagen and elastin production while simultaneously providing deep, sustained hydration to surrounding tissues. The result is a gradual bio-remodelling effect rather than an immediate structural change.
Areas Suitable for Profhilo
Profhilo treatments are commonly performed across a broad range of anatomical areas, reflecting the product’s versatility:
- Face – particularly cheeks, jawline, and perioral area
- Neck – to address laxity and crepey texture
- Décolletage – for skin quality improvement on the chest
- Hands – to reduce thinning and visible veining
- Arms – for crepey or loose skin on the upper arms
- Abdomen and knees – less common but practised by some specialists
Benefits of Profhilo
Profhilo offers a range of skin-enhancing benefits that make it a popular choice for patients concerned with early-to-moderate signs of skin ageing:
- Significant improvement in hydration and moisture retention
- Enhanced elasticity and firmness
- Reduction in crepey or thin skin appearance
- Improved texture and radiance
- Gentle stimulation of collagen and elastin without structural change
- Suitable for patients who wish to avoid volumising treatments
What Are Polynucleotides?
Polynucleotides are advanced injectable treatments derived from purified DNA fragments — typically from salmon or trout — that have been extensively processed to remove allergenic proteins. Used in regenerative aesthetic medicine, polynucleotides work at a cellular level to support tissue repair, stimulate skin cells, and promote structural renewal. They are increasingly used across face and neck areas as well as more specialist applications such as the under-eye zone.
How Polynucleotides Work
Polynucleotides work by activating fibroblasts — the cells responsible for producing collagen and elastin — and promoting DNA and RNA synthesis within the skin. This mechanism triggers tissue repair and cellular renewal rather than simply hydrating or filling. Polynucleotides stimulate the body’s own regenerative capacity, which may make them particularly effective for patients with more significant skin damage or poor quality.
Areas Suitable for Polynucleotide Treatments
Polynucleotides are suitable for a variety of areas where regenerative improvement is the goal:
- Face – overall skin quality, fine lines, and texture
- Under-eye area – one of the most frequently treated zones
- Neck and décolletage – skin laxity and crepiness
- Scalp – used in some hair thinning protocols
- Hands – for quality improvement
- Acne-scarred skin – where tissue repair is a primary concern
Benefits of Polynucleotides
Polynucleotides offer a distinctive profile of regenerative benefits that differentiate them from hydration-focused injectables:
- Stimulation of collagen production at the cellular level
- Improved skin elasticity over the course of treatment
- Reduced inflammation and oxidative stress within skin tissues
- Enhanced quality in areas with sun damage or scarring
- Support for fibroblast activity and tissue renewal
- Beneficial for under-eye hollowing and skin thinning in delicate zones
Profhilo vs Polynucleotides: How They Work Differently
Both treatments improve skin appearance, but the differences between polynucleotides and profhilo in terms of biological mechanism are substantial. Profhilo works primarily through hydration and indirect stimulation, while polynucleotides work directly at a cellular level to trigger repair. Understanding this distinction helps clarify when each treatment may be more appropriate.
Hydration and Bio-Remodelling With Profhilo
Profhilo delivers a high concentration of hyaluronic acid that spreads beneath the skin across a wide tissue plane. This distribution supports moisture retention across a broad area while simultaneously stimulating fibroblasts to produce collagen and elastin. The hydration and stimulating effect remodels tissue gradually, improving skin quality from within rather than through structural augmentation.
Regeneration and Tissue Repair With Polynucleotides
Polynucleotides are a regenerative injectable that act at the cellular level, promoting DNA repair pathways, reducing oxidative damage, and triggering fibroblast activity. This process supports the renewal of skin cells and the structural matrix, making polynucleotides particularly relevant for patients whose skin concerns stem from cellular damage rather than dehydration alone. The mechanism is slower but more deeply reparative in nature.
Impact on Collagen and Elastin Production
Profhilo | Polynucleotides | |
Collagen stimulation | Indirect – via HA-driven fibroblast activation | Direct – via cellular repair pathway activation |
Elastin stimulation | Yes, as part of bio-remodelling response | Yes, as part of structural renewal |
Collagen production timeline | Gradual over 4–8 weeks post-treatment | Gradual; builds over a course of 3–4 sessions |
Primary driver | Hydration and moisture scaffolding | DNA repair and cell regeneration |
Profhilo vs Polynucleotides: Results and Benefits
When comparing polynucleotides vs Profhilo in terms of visible results, the distinction often comes down to the primary skin concern. Both treatments can improve quality, but their outputs differ in character and emphasis.
Skin Hydration and Glow
Profhilo is often the preferred option when the primary concern is dehydrated, dull, or lacklustre skin. Its hyaluronic acid concentration provides rapid improvement in skin hydration, and patients frequently report a visible glow and improved plumpness after completing a two-session protocol. Clinical studies suggest it can meaningfully improve elasticity and moisture levels within weeks of treatment.
Skin Repair and Texture Improvement
Polynucleotides improve skin quality through a different pathway and may offer greater benefit in cases where damage, scarring, or chronic poor texture is the concern. The regenerative mechanism supports skin texture improvement at a structural level, and polynucleotides offer gradual but sustained results in patients with sun-damaged, thinning, or acne-affected skin. Results may continue to improve over several months following the final session.
Natural-Looking Rejuvenation
Both treatments enhance skin appearance without significantly altering facial features or adding volume, which is why they are frequently described as natural-looking rejuvenation options. Neither profhilo nor polynucleotides produce the structural changes associated with dermal fillers. The outcomes are more subtle and cumulative — improved skin quality, texture, and vitality rather than a visible change in facial shape.
Profhilo vs Polynucleotides: Treatment Process and Recovery
Number of Sessions Required
The typical treatment protocols differ between the two injectables:
Profhilo protocol:
- 2 sessions, spaced 4 weeks apart
- Maintenance sessions typically recommended every 6–9 months
- Some practitioners recommend a third session in older patients or those with more significant laxity
Polynucleotide protocol:
- 3–4 sessions, spaced 2–4 weeks apart
- Maintenance sessions vary by product and practitioner recommendation
- Results often build progressively across the full course
Procedure Experience
Both treatments involve fine-needle injections administered by a trained aesthetic practitioner, typically with topical anaesthetic cream applied beforehand:
- Profhilo: Uses the BAP (Bio Aesthetic Points) technique, placing product at 5 precise anatomical points per side on the face; treatment usually takes 20–30 minutes
- Polynucleotides: Injected via multiple small injection points across the treatment area; technique varies by product and practitioner; takes approximately 30–45 minutes
- Discomfort is generally described as mild and well-tolerated by most patients
Downtime and Side Effects
Both treatments carry a comparable and generally minimal side effect profile:
- Small bumps or swelling at injection sites (usually resolve within hours to 24 hours for Profhilo; up to 48 hours for polynucleotides)
- Mild redness at injection points
- Occasional bruising, particularly in the under-eye area
- Rare risk of infection, vascular occlusion, or allergic response — suitability should always be assessed by a qualified practitioner
- No significant downtime; most patients return to normal activities the same day
Who Is Suitable for Profhilo or Polynucleotides?
Best Candidates for Profhilo
Profhilo is ideal for patients presenting with the following concerns:
- Mild to moderate skin laxity and loss of firmness
- Dehydrated or dull skin lacking radiance
- Crepey texture on the face, neck, or body
- Patients seeking improved hydration and elasticity without structural change
- Those who prefer a shorter treatment course
- Patients aged roughly 30–60, noticing early to moderate signs of skin ageing
Best Candidates for Polynucleotides
Polynucleotides may be more appropriate for patients with:
- Moderate to significant skin quality concerns, including sun damage
- Under-eye hollowing, dark circles, or periorbital skin thinning
- Acne scarring or skin affected by inflammation and tissue damage
- Patients seeking cellular-level regeneration rather than primarily hydration
- Those with skin concerns linked to structural or cellular deterioration
- Hair thinning protocols where scalp regeneration is relevant
When Combination Treatments May Be Recommended
Independent aesthetic specialists sometimes recommend combining profhilo and polynucleotides within a personalised treatment plan, particularly when a patient presents with both dehydration and skin quality concerns simultaneously. Some practitioners sequence treatments — polynucleotides first to support cellular repair, followed by Profhilo to enhance hydration and elasticity — or use them in parallel across different areas. Suitability for combination treatment depends on individual anatomy, medical history, and clinical assessment, and should always be determined through a thorough consultation.
Final Verdict: Profhilo vs Polynucleotides – Which Treatment Is Better?
Neither Profhilo nor polynucleotides is universally superior — the right treatment depends on individual skin condition, age-related concerns, and personal treatment goals. Profhilo is typically better suited to patients whose primary concern is hydration and skin firmness, while polynucleotides may be preferable where cellular regeneration, tissue repair, or targeted concerns such as under-eye rejuvenation are the priority. In many cases, both have a role to play within a broader injectable skin treatments strategy.
Deciding between profhilo and polynucleotides is ultimately a clinical decision. A personalised consultation with a qualified aesthetic practitioner is the most reliable way to make an informed choice about which treatment — or combination — best aligns with your needs and goals.
Frequently Asked Questions
Can Profhilo and Polynucleotides Be Combined?
Yes, profhilo and polynucleotides can be used together as part of a personalised treatment plan when a patient has both hydration deficits and skin quality concerns. Some practitioners recommend them in sequence or simultaneously across different areas. Combined approaches may enhance overall outcomes, but suitability depends on individual assessment and should always be discussed during a consultation with a qualified specialist.
Which Treatment Lasts Longer?
Both treatments provide results that are temporary and gradually absorbed by the body over time. Profhilo results typically last around 6–9 months, while polynucleotides can last from 6 to 12 months depending on the specific product used, the number of sessions completed, individual metabolism, and the severity of the original skin concern. Maintenance treatments are generally recommended for both.
Are Profhilo and Polynucleotides Fillers?
Neither Profhilo nor polynucleotides are traditional dermal fillers. Profhilo is classified as a skin booster that redistributes throughout the tissue to hydrate and remodel without adding structural volume. Polynucleotides are a regenerative injectable focused on cellular repair. Both are distinct from conventional fillers, which are designed to add volume, projection, or structural support to specific facial areas.
Which Treatment Is Better for Under-Eye Rejuvenation?
Polynucleotides are frequently chosen for under-eye rejuvenation due to their regenerative properties and suitability for the thin, delicate periorbital skin. They may help improve skin thinning, dark circles linked to poor skin quality, and texture in the under-eye area. Profhilo is used in this area by some practitioners, but polynucleotides are generally considered the more targeted option. Recommendations remain practitioner-dependent and require individual assessment.
