The Complete Guide to Polynucleotide Skin Boosters

Polynucleotide skin boosters represent one of the most significant advances in regenerative aesthetics. Derived from purified DNA fragments, these injectable treatments work at a cellular level to rejuvenate and repair skin from within. At Axiom Aesthetics, our practitioners have seen remarkable results with polynucleotide therapy, and we believe every patient deserves to understand exactly what this treatment involves.

What Are Polynucleotides?

Polynucleotides (PNs) are long chains of nucleotides — the building blocks of DNA and RNA. In aesthetic medicine, polynucleotides used in skin boosters are typically derived from salmon or trout DNA, which has been purified through a rigorous pharmaceutical process to remove all proteins and potential allergens.

Unlike hyaluronic acid fillers that primarily add volume, polynucleotides work by stimulating your skin’s own regenerative processes. They act as biostimulators, encouraging fibroblasts to produce more collagen, elastin, and hyaluronic acid naturally. Research published in the Journal of Cosmetic Dermatology (2023) demonstrates that polynucleotide treatments can increase collagen synthesis by up to 47% over a course of treatments.

How Polynucleotide Skin Boosters Work

When injected into the dermis, polynucleotides trigger several biological mechanisms:

• Fibroblast stimulation: PNs activate fibroblast proliferation, the cells responsible for producing collagen and elastin
• Anti-inflammatory action: They reduce oxidative stress and free radical damage at a cellular level
• Hydration enhancement: PNs attract and bind water molecules, improving skin hydration from within
• Tissue repair: They accelerate the skin’s natural wound healing and tissue regeneration processes
• Antioxidant protection: Polynucleotides scavenge free radicals, protecting cells from environmental damage

The Science Behind the Treatment

At a molecular level, polynucleotides interact with purinergic receptors on cell surfaces. This triggers intracellular signalling cascades that upregulate the production of extracellular matrix components. The result is thicker, more hydrated, and more resilient skin that looks naturally healthier rather than artificially enhanced.

A landmark study by Cavallini et al. (2021) in Aesthetic Surgery Journal demonstrated that polynucleotide injections led to measurable improvements in skin elasticity (23% improvement), hydration (31% improvement), and overall skin quality within just three sessions.

Popular Polynucleotide Products in the UK

Several polynucleotide products are available for aesthetic use in the United Kingdom:

Ameela

One of the first polynucleotide products to gain widespread use in UK aesthetics clinics. Ameela contains highly purified polynucleotides and is available in two formulations — one for the face and a stronger concentration for the body. It is CE-marked and has an excellent safety profile.

Nucleofill

Nucleofill offers a range of polynucleotide products targeting different treatment areas. Their formulations vary in concentration, allowing practitioners to tailor treatments to specific skin concerns and anatomical zones. The product line includes options for the under-eye area, face, and body.

Pluryal Silk

A newer entrant to the UK market, Pluryal Silk combines polynucleotides with hyaluronic acid for a dual-action approach. This combination provides both immediate hydration and long-term biostimulation.

What to Expect During Treatment

Understanding the treatment process helps patients feel confident and prepared. Here is what a typical polynucleotide treatment session involves at our treatment clinic:

Before Treatment

• A thorough skin assessment and medical history review during your initial consultation
• Discussion of your skin concerns, goals, and realistic expectations
• Photographs taken for before-and-after comparison
• Topical anaesthetic cream applied for 20-30 minutes (optional but recommended)

During Treatment

The polynucleotide solution is injected using a fine needle or cannula, depending on the treatment area. Multiple small injections are placed across the treatment zone using techniques such as:

• Serial puncture: Small deposits at regular intervals across the skin
• Linear threading: The product is deposited along linear paths beneath the skin
• Blanching technique: Superficial injections in the papillary dermis for under-eye treatments

The entire procedure typically takes 30-45 minutes, including preparation time.

After Treatment

Most patients experience mild redness, small bumps at injection sites, and occasional minor bruising. These effects typically resolve within 24-48 hours. We provide detailed aftercare instructions to optimise your results.

Treatment Areas and Indications

Polynucleotide skin boosters can be used across numerous areas of the face and body:

• Face: Overall skin rejuvenation, fine lines, dull complexion
• Under-eyes: Dark circles, crepey skin, hollowing (a particularly popular treatment area)
• Neck: Horizontal lines, crepey texture, loss of firmness
• Decolletage: Sun damage, fine lines, loss of elasticity
• Hands: Volume loss, thinning skin, prominent veins
• Scalp: Hair thinning and hair quality improvement

Treatment Protocol and Timeline

For optimal results, we typically recommend the following protocol:

• Initial course: 3-4 sessions spaced 2-4 weeks apart
• Results timeline: Initial improvements visible after 2-3 weeks; full results at 2-3 months post-final session
• Maintenance: One session every 4-6 months to maintain results
• Duration of effects: Results typically last 6-12 months, depending on individual factors

Who Is a Good Candidate?

Polynucleotide skin boosters are suitable for a wide range of patients. Ideal candidates include those who:

• Have early signs of ageing such as fine lines and loss of skin radiance
• Experience dehydrated or dull-looking skin despite a good skincare routine
• Want to improve skin texture and elasticity without adding volume
• Have dark under-eye circles or crepey under-eye skin
• Are looking for a natural-looking, gradual improvement in skin quality
• Want to combine treatment with other aesthetic procedures for comprehensive rejuvenation

Contraindications

As with any injectable treatment, there are certain situations where polynucleotides may not be appropriate. These include pregnancy and breastfeeding, active skin infections at the treatment site, known allergy to fish-derived products, autoimmune conditions affecting the skin, and patients taking anticoagulant medication (relative contraindication).

Safety and Side Effects

Polynucleotide skin boosters have an excellent safety profile when administered by qualified practitioners. The most common side effects are mild and temporary:

• Redness at injection sites (resolves within hours)
• Small papules or bumps (resolve within 24-48 hours)
• Minor bruising (resolves within 5-7 days)
• Mild swelling (resolves within 1-3 days)

Serious complications are extremely rare. The purification process removes virtually all allergenic proteins, making true allergic reactions exceptionally uncommon. However, as with any injectable procedure, there is a small risk of infection, which is minimised through proper aseptic technique.

Frequently Asked Questions

Are polynucleotide skin boosters painful?

Most patients report minimal discomfort, especially when topical anaesthetic is applied beforehand. The needles used are very fine (typically 30-32 gauge), and many describe the sensation as a series of tiny pinpricks. The under-eye area tends to be the most sensitive treatment zone, but even this is well-tolerated by the majority of patients.

How soon will I see results from polynucleotide treatment?

Initial improvements in skin hydration and radiance may be noticeable within 1-2 weeks of the first session. However, the full biostimulatory effects — including increased collagen production and improved skin elasticity — develop over 2-3 months following the completion of the initial treatment course. Patience is key, as the results build progressively.

Can polynucleotides be combined with other aesthetic treatments?

Yes, polynucleotide skin boosters can be an excellent complement to other treatments. They pair well with anti-wrinkle injections, dermal fillers, chemical peels, and laser treatments. Your practitioner at Axiom Aesthetics will advise on optimal treatment spacing and combinations during your consultation.

Are polynucleotide treatments suitable for all skin types?

Polynucleotide skin boosters are suitable for all Fitzpatrick skin types (I-VI). Unlike some laser or light-based treatments, there is no increased risk of hyperpigmentation in darker skin tones. This makes PNs an excellent option for patients of all ethnicities and skin colours.

How much do polynucleotide skin boosters cost in the UK?

The cost of polynucleotide treatments varies depending on the product used, the treatment area, and the number of sessions required. In the UK, a single session typically ranges from £250 to £450, with a full course of three sessions costing between £700 and £1,200.
