    Dr Harry is absolutely amazing, I can’t recommend him enough. I had my usual skin maintenance treatments yesterday, and for the first time I decided to try a lip booster. Harry was so informative, knowledgeable, and reassuring throughout, and he made me feel completely at ease. I was originally offered standard lip filler, but as I’m in my 60s I wanted something more subtle and natural-looking, the lip booster felt like the perfect choice. I left the clinic with only a little swelling (nothing too bad at all) and my lips already look healthier, more youthful, and beautifully natural. I’m genuinely thrilled with the result and can’t thank him enough. Five-star-plus treatment every time. His prices are very reasonable, and his manner with patients is kind, professional, and wonderful. I’m already looking forward to my next appointment, even if I have to wait a few months because the results last so well. Thank you Dr. Harry ❤️

    Dr. Harry is incredibly knowledgeable and really takes his time to talk you through everything, answer any questions, and ensure you’re comfortable throughout the whole appointment. I never felt rushed, and he explained the treatment and expected results clearly, which made me feel really confident in the process. I’m so pleased with my results and wouldn’t hesitate to recommend him.

    Great experience for an ultrasound-guided filler dissolution treatment. Dr Harry was very patient, caring and professional. I really appreciated the thorough consultation and felt well looked after throughout the treatment. Very happy with the results!

    I visited Dr Harry after having my lips done by a few, other practitioners and my experience was positively incomparable. Harry was extremely thorough with his questioning, support and actual practice, I felt reassured and at ease, alike did my Mum, at the hands of Harry. I had 0.6ml of lip filler and was extremely impressed that he reevaluated my lips afterwards, adding in the remaining filler into specific areas. I did not have 1 single bruise, despite coming up black and blue in the past, and my lips are the most symmetrical they have ever looked. 1 million percent the best investment I have made to my face and I would never recommend going to anybody else! I visited the Chiswick clinic and it was beautiful🫶🏼 thank you Harry

    I went to Dr Harry Clinic after both a recommendation and doing a lot of research, as this was my first anti-wrinkle injection treatment and choosing someone I truly trusted was really important to me. From the moment I arrived, Dr. Harry immediately made me feel at ease. He was so lovely, professional, and took the time to explain everything in detail. Most importantly, he really listened to what I wanted - especially my preference for a very natural look. Two weeks later, I had my complimentary follow-up appointment and I was already so happy with the results. At the follow-up, Harry was an absolute perfectionist, carefully assessing everything to ensure it was as balanced and natural as possible, with a small top-up where needed. Overall, my experience exceeded all expectations. If it’s your first time having treatment, or you’re looking for a new injector, I genuinely cannot recommend Dr Harry Clinic enough. One of the best decisions I’ve made.

Understanding Polynucleotides

Polynucleotides are an advanced injectable treatment that uses purified DNA fragments to trigger the skin’s natural repair systems. Acting at a cellular level, they stimulate fibroblast activity, encourage new collagen production, and enhance blood flow, all of which contribute to visible, long-term improvement in skin quality.

These DNA chains, derived from biocompatible sources, are absorbed by the body and work by supporting tissue regeneration rather than masking imperfections. The result is a healthier, more resilient skin barrier and a visibly fresher complexion.

At Dr Harry Clinic, Polynucleotide treatments are delivered with expert precision, ensuring the product is placed where it can most effectively promote cellular renewal and skin optimisation.

Polynucleotides Treatment Explained

01The Science of DNA Skin Regeneration

Polynucleotide therapy is rooted in regenerative science, not just aesthetic correction. It delivers DNA building blocks that act as messengers, encouraging skin cells to:

  • Repair environmental and age-related damage

  • Stimulate new blood vessel formation (angiogenesis)

  • Produce collagen and elastin for improved structure

  • Enhance hydration and skin metabolism

The DNA fragments used in this treatment are often sourced from purified salmon DNA, chosen for its compatibility and effectiveness in supporting human skin regeneration. Once injected, they integrate into the surrounding tissue and promote true skin revitalisation, not temporary filling.

02Where Polynucleotides Can Be Used

Polynucleotides are suitable for any area of the skin showing signs of ageing, dullness, or weakened structure. They are particularly effective in delicate or challenging areas:

Full Face Regeneration

Ideal for patients with uneven texture, fine lines, dull tone, or early loss of firmness. Polynucleotides work gradually to rebuild dermal quality, offering natural enhancement that evolves over weeks.

Periorbital Area (Under-Eyes)

Thin, fragile under-eye skin benefits significantly from this regenerative approach. Treatment helps reduce crepiness, fine lines, and dull tone in a way that traditional fillers cannot.

Neck & Décolletage

Polynucleotides support improved elasticity and hydration in these delicate areas, often neglected but prone to early signs of ageing.

03Advanced Injection Techniques

For best results, Polynucleotides require careful placement at the right depth and diffusion pattern. Treatments at our clinic are delivered using micro-injection protocols that:

  • Distribute the product evenly across the targeted area

  • Minimise trauma and downtime

  • Encourage optimal integration with the surrounding tissue

Injection patterns are selected based on anatomical knowledge and the specific needs of your skin, whether it’s crepiness under the eyes, poor texture on the neck, or general dullness across the face.

04Gradual, Natural-Looking Results

Polynucleotide treatments are designed for progressive skin renewal, not instant transformation. This makes them ideal for individuals seeking long-term improvements in skin health and resilience.

You can expect:

  • Weeks 2 to 4: Smoother texture, improved hydration

  • Weeks 4 to 8: Firmer skin, brighter tone

  • Weeks 8 to 16: Visible regeneration and glow, with fewer fine lines and greater skin density

Because the treatment supports natural skin behaviour, the results look and feel authentic, never artificial or overfilled.

05Sustaining Results Through Maintenance

A typical course involves 3 sessions spaced 2 to 3 weeks apart, depending on the area and condition of the skin. Results can last 6 to 9 months or more, especially when supported by an effective skincare regimen.

Maintenance sessions can be performed biannually or as part of a tailored aesthetic plan, helping preserve long-term skin vitality and collagen density.

06Combining Polynucleotides with Other Treatments

Polynucleotides are highly versatile and pair beautifully with other skin therapies. They are often integrated into broader treatment programmes, including:

  • Skin boosters like Profhilo or Belotero Revive

  • Botulinum toxin for fine line prevention

  • Microneedling or mesotherapy for added stimulation

  • Light energy devices to complement cell turnover

Because Polynucleotides work beneath the surface, they enhance rather than compete with other treatments, often leading to better overall skin outcomes.

07Ideal Candidates for Polynucleotides

This regenerative therapy is suitable for both men and women who want to:

  • Improve texture, tone, and skin quality

  • Strengthen fragile or environmentally damaged skin

  • Treat hard-to-fill areas like under the eyes or neck

  • Avoid volume-heavy fillers or aggressive resurfacing

  • Support long-term skin health with minimal downtime

It is also an excellent option for younger patients beginning preventative skin care, and for mature skin in need of biological support rather than surface-level correction.

Common questions

Polynucleotides Treatment FAQs

01What are polynucleotides and how do they work in skin regeneration?

Polynucleotides are highly purified DNA fragments derived from salmon that stimulate your skin’s natural repair and regeneration processes. They work by activating fibroblasts, promoting angiogenesis (formation of new blood vessels), and boosting collagen production, leading to visibly smoother, firmer, and more radiant skin over time.

02How is Polynucleotide treatment different from traditional skin boosters or fillers?

While skin boosters like Profhilo provide hydration and dermal fillers add volume, Polynucleotides actively regenerate the skin at a cellular level. This means the treatment doesn’t simply mask signs of ageing, it helps restore skin function and structure by enhancing DNA repair, making it ideal for improving texture, tone, and resilience.

03Is Polynucleotide treatment suitable for the under-eye area?

Yes. Polynucleotides are particularly effective for the delicate periorbital region, improving fine lines, dark circles, and crepey texture without adding volume. Dr Harry uses precise micro-injection protocols to ensure safe, targeted treatment and optimal regenerative results around the eyes.

04How many sessions will I need to see results?

Most patients require an initial series of 3 sessions spaced 2 to 4 weeks apart to achieve full regenerative effects. Visible improvements typically begin after 2 to 3 weeks, with continued enhancement over 2 to 3 months as cellular repair progresses. Dr Harry will recommend a personalised maintenance plan based on your skin’s response.
