If skin quality is the goal, not volume, not structure, just genuinely better skin, then two treatments consistently come up in conversation: Profhilo and polynucleotides. Both are injectable skin boosters. Both improve skin from within. And both are increasingly popular with patients who want to look refreshed and healthy without the changes associated with fillers or anti-wrinkle injections.
But they are not the same treatment, and understanding the difference matters when choosing which is right for a particular skin concern and stage of ageing.
This guide provides an honest, detailed comparison of Profhilo and polynucleotides in 2026, how each works, what results to expect, who each is best suited to, and when combining both treatments makes the most sense. As a medically led aesthetics clinic in Liverpool, Doctor Naz Clinic offers both treatments as part of a personalised skin programme and will always recommend the approach that is genuinely right for the skin in front of it.
What Is Profhilo?
Profhilo is a bio-remodelling injectable made from one of the highest concentrations of ultra-pure hyaluronic acid (HA) available in an injectable product, 64mg per 2ml syringe. Unlike traditional HA fillers, Profhilo is not designed to add volume or structure to the face. Instead, it spreads through the tissue to deeply hydrate and triggers a process called bio-remodelling, stimulating the production of four types of collagen and elastin.
The treatment uses a patented NAHYCO technology that combines high and low molecular weight HA in a single product. The high molecular weight HA provides immediate and sustained hydration; the low molecular weight HA penetrates more deeply and stimulates the skin’s own regenerative processes.
Profhilo is administered at five specific injection points on each side of the face, known as Bio Aesthetic Points (BAPs) and requires two sessions, spaced four weeks apart. Full results are visible at around six to eight weeks and last approximately six to nine months.
Best suited to: patients aged roughly 30–55 with skin laxity, loss of hydration, reduced bounce or elasticity, and early signs of ageing. It delivers a notably quick improvement in radiance and glow, making it a popular choice for patients who want visible results relatively fast.
What Are Polynucleotides?
Polynucleotides (PDRN/PN) are injectable molecules derived from highly purified DNA fragments typically sourced from salmon or trout sperm, which share a high degree of genetic compatibility with human DNA. They are not fillers, and they are not HA; they are biostimulators that work at a cellular level.
Once injected into the skin, polynucleotides act as cellular signalling molecules: they activate fibroblasts (the cells responsible for producing collagen and elastin), promote tissue repair, improve microcirculation, and have notable anti-inflammatory and antioxidant effects. The result is a gradual but meaningful improvement in skin quality, firmer, more resilient, and healthier skin driven by the body’s own regenerative processes rather than an external substance.
Polynucleotides are particularly well suited to areas of delicate or fragile skin, the under-eye area, the neck, and areas with advanced photoaging or textural damage. They are also an excellent option for patients with sensitive or reactive skin, as the anti-inflammatory effect can help calm the skin while improving its structure.
Treatment typically involves three to four sessions spaced two to four weeks apart. Results build gradually over two to three months and last eight to twelve months.
Best suited to: patients with more advanced photoaging, textural irregularities, crepey or fragile skin, under-eye concerns, or those looking for meaningful long-term regeneration rather than a quick hydration boost.
Which Gets Better Results?
This is the question most patients ask, and the honest answer is that it depends entirely on the skin concern and the goal.
Profhilo gets better results when the goal is:
- Rapid improvement in skin hydration and radiance
- Restoring skin bounce and elasticity — the ‘glass skin’ effect
- Treating early to moderate skin laxity in patients aged 30–55
- A two-session protocol with visible results within weeks
- A foundation treatment to complement other injectables
Polynucleotides get better results when the goal is:
- Treating fragile, crepey, or thin skin, especially around the eyes or neck
- Addressing advanced photoaging, textural damage, or uneven skin quality
- Genuine cellular regeneration rather than a hydration boost
- Longer-lasting results with a more gradual, sustained improvement
- For sensitive or inflamed skin, the anti-inflammatory effect is clinically meaningful
For many patients, the answer is not either/or but both, used sequentially or in combination. Profhilo for immediate hydration and remodelling, followed by polynucleotides for deeper regeneration, is an approach increasingly recommended by practitioners for comprehensive skin rejuvenation. At Doctor Naz Clinic, combination protocols are discussed with patients where appropriate.
Who Is Each Treatment Best Suited To?
Consider Profhilo if:
- The skin feels dry, dull, or lacks elasticity
- Early signs of ageing are visible, but structural volume loss is not yet significant
- A quicker visible result is desired. Profhilo’s glow effect is noticeable within days
- Treatment of the full face, neck, or décolletage as a single protocol is preferred
- This is a first injectable skin treatment, and a well-tolerated, low-complexity option is preferred
Consider polynucleotides if:
- The skin is thin, fragile, or has significant texture concerns
- The under-eye area is the primary concern polynucleotides are particularly effective here
- There is photodamage, sun-related ageing, or significant textural irregularity
- A longer-lasting result with gradual improvement over time is the priority
- The skin is sensitive or prone to inflammation — polynucleotides actively calm the skin
Consider combining both if:
- Comprehensive skin quality improvement is the goal
- Both dehydration and textural concerns are present
- The patient is in their 40s or 50s with multiple early ageing signs
- A previous single-treatment approach has not delivered the full result desired
What to Expect from Treatment at Doctor Naz Clinic
Regardless of which treatment is chosen, the patient journey at Doctor Naz Clinic follows the same principles: a proper consultation, personalised recommendation, and thorough aftercare.
Profhilo treatment:
- Session 1: five injection points per side of the face — approximately 20 minutes
- Session 2: four weeks later, same protocol
- Results: visible hydration and glow within days; full bio-remodelling effect at 6–8 weeks
- Downtime: mild swelling or small injection bumps for 24–48 hours
- Maintenance: top-up session every 6–9 months
Polynucleotide treatment:
- Sessions 3–4 treatments, spaced 2–4 weeks apart — multiple microinjections across the treatment area
- Treatment time: 30–45 minutes per session
- Results: gradual improvement over 2–3 months as collagen remodelling progresses
- Downtime: mild redness or small papules settling within 24 hours
- Maintenance: top-up treatment every 9–12 months
Frequently Asked Questions
Are polynucleotides and Profhilo the same as skin boosters?
The term ‘skin booster’ is used broadly and can refer to several different injectable products. Profhilo and polynucleotides are both sometimes called skin boosters, but they are distinct treatments with different mechanisms. Traditional HA skin boosters, such as Restylane Skinboosters, are lightly cross-linked HA gels placed superficially to hydrate and subtly fill fine lines. Profhilo is a bio-remodelling product; polynucleotides are biostimulators. All three improve skin quality, but in different ways.
Do polynucleotides or Profhilo hurt?
Both treatments are generally well tolerated. A topical numbing cream is applied before either treatment to minimise discomfort. Profhilo uses five injection points per side, which most patients describe as mild pressure. Polynucleotides involve multiple microinjections across the treatment area. The sensation is similar to a series of small pinches. Both treatments have minimal downtime.
How quickly will I see results from each treatment?
Profhilo produces visible improvement in hydration and radiance within days of the first session. Polynucleotides work more gradually meaningful improvement typically becomes apparent after the second or third session, with full results building over two to three months. Both treatments continue to improve the skin over time.
Can polynucleotides and Profhilo be done at the same appointment?
In some cases, yes, but this depends on the individual treatment plan, the areas being treated, and the patient’s skin. A consultation will determine whether a combined or sequential protocol is most appropriate. Doctor Naz Clinic will never combine treatments simply for convenience; the plan will always be driven by what is clinically right for the skin.
Are there any reasons I could not have either treatment?
Both treatments are generally well tolerated, but there are contraindications. Treatment is not recommended during pregnancy or breastfeeding, for patients with active skin infections in the treatment area, or for those with certain autoimmune conditions. A full medical consultation will always be carried out before any treatment at Doctor Naz Clinic to establish suitability.
