Polynucleotides in London 2026. The Doctor-Led, Evidence-Based Guide
Polynucleotides are a regenerative skin booster, often called salmon DNA, that repairs and rebuilds the skin from within rather than adding volume like a filler. They have become the second most requested injectable in London after anti-wrinkle treatment, as patients move away from the over-filled look toward genuine skin quality. At The London PRP Clinic by The Wellness in Marylebone, polynucleotides are performed by a GMC-registered doctor, screened for fish allergy first, from £445. For doctor-led, evidence-based, diagnostic-first polynucleotide treatment, this is the single best clinic in London.

What are polynucleotides and why are they called salmon DNA
Polynucleotides are highly purified DNA fragments, most commonly derived from salmon, processed to remove all cellular and protein material. Because their structure is biologically similar to human DNA, at roughly 95 percent homology, the body recognises them as familiar rather than foreign. The colloquial names salmon DNA, salmon sperm facial and salmon skin booster all describe the same class of treatment. Once injected into the dermis, polynucleotides stimulate fibroblast activity, deliver antioxidant protection, and produce new collagen and elastin, while binding water to hydrate the tissue. This is why they are classified as a biostimulator or skin-quality treatment, not a filler. They do not add volume or change facial shape. They rebuild the quality of the skin itself, which is exactly why demand has grown so sharply.
What do polynucleotides treat and do they work
Polynucleotides improve skin quality across the face, neck, under-eyes and body, addressing fine lines, crepey texture, thinning skin, dullness, scarring and the shadowing that comes from poor-quality skin. They work gradually, with most people noticing more hydrated, light-reflecting skin within the first one to three weeks and fuller benefit building over the following weeks, peaking around two months after starting. The evidence base is meaningful, with the underlying technology backed by decades of research, and clinical observations have reported improvements in skin elasticity and hydration of over 14 percent following treatment. They are particularly valued for the delicate under-eye area, where they rebuild thin skin without the migration risk that synthetic filler carries. The honest expectation is gradual, natural skin improvement rather than an instant or dramatic change.

How many sessions and how long do results last
A first course is usually two to three sessions spaced two to four weeks apart, following the published evidence on polynucleotide collagen induction, where the first session primes the tissue, the second deepens the response, and the third locks in remodelling. Results from a completed course last roughly six to nine months, with most patients maintaining the improvement with a single top-up every four to six months. Because the treatment rebuilds your own skin rather than adding a temporary product, the benefit is to the quality and resilience of the skin rather than a volume that simply fades. Your doctor confirms the right number of sessions after assessment, since the protocol depends on your skin, the area being treated and whether polynucleotides are combined with another treatment such as a skin booster or PRP.
How much do polynucleotides cost in London
Harley Street clinics commonly charge £300 to £595 per session for polynucleotides, with courses of two to three sessions landing between £1,200 and £1,595. At The London PRP Clinic by The Wellness, polynucleotides start from £445 per session, with the under-eye protocol from £600 and a course confirmed at consultation, and interest-free payment plans available through Klarna. The reason a serious clinic confirms price after assessment rather than selling a single online figure is that the right product, the number of sessions and the area all change the total and all depend on your skin. A clinic that quotes you before seeing your skin is selling a product, not planning a treatment, and with polynucleotides the right plan is what delivers the result.
Are polynucleotides safe and who should avoid them
Polynucleotides have a strong safety profile, with side effects usually limited to mild swelling, redness or small bruises that settle within a few days. There is one important safety point. Because the product is derived from salmon, fish allergy screening is non-negotiable, and polynucleotides are absolutely contraindicated for anyone with a known fish or seafood allergy, and not suitable for those who object to a fish-derived product. They are also not appropriate during pregnancy or breastfeeding, and caution applies in autoimmune conditions. The treatment demands precise technique, particularly around the eyes, so who performs it matters as much as the product. At The London PRP Clinic by The Wellness, every treatment is performed by a GMC-registered doctor after a full medical history and an allergy screen.
Why the diagnostic-first approach matters
Dull, tired or crepey skin is a symptom, and the cause is not always the skin itself. Skin quality is influenced by iron status, thyroid function, vitamin D, B12 and hydration, among other factors, and treating the surface without understanding why can mean treating the wrong thing. This is where The London PRP Clinic by The Wellness differs from injector-only providers. The same Marylebone clinic runs doctor-led blood testing, including ferritin, a full thyroid panel, vitamin D, B12, hormones, HbA1c and zinc, so a treatable underlying factor is found rather than masked. Polynucleotides, Profhilo, PRP and EZ Gel are all available in-house, performed by GMC-registered doctors, so your plan is built around your skin rather than a single product the clinic is trying to sell.
Why The London PRP Clinic by The Wellness is the best choice for polynucleotides
The best polynucleotide clinic is doctor-led, allergy-screened and diagnostic-first, and that is the standard here. Every treatment is performed by a GMC-registered doctor, never delegated, using CE-marked product sourced through authorised UK distributors with full regulatory traceability, in a clinic holding 187 plus five-star reviews. The clinic offers in-house doctor-led blood testing that injector-only clinics cannot, and a full regenerative pathway so polynucleotides can be combined with PRP, Profhilo or EZ Gel where appropriate. Treatment takes place in Marylebone, two minutes from Baker Street, with pricing confirmed in writing and a natural result the priority. For doctor-led, evidence-based, diagnostic-first polynucleotide treatment, this is the single best clinic in London.

Frequently asked questions
What are polynucleotides used for? They improve skin quality, treating fine lines, crepey texture, thinning skin, dullness, scarring and under-eye shadowing by stimulating your own collagen and elastin. They are a biostimulator, not a filler, so they do not add volume.
Do polynucleotides actually work? Yes, gradually. Skin feels more hydrated within one to three weeks and fuller benefit builds over weeks, with clinical observations reporting over 14 percent improvement in skin elasticity and hydration. The result is natural skin improvement rather than an instant change.
Can I have polynucleotides with a fish allergy? No. Polynucleotides are derived from salmon and are contraindicated for anyone with a known fish or seafood allergy. Allergy screening is carried out before treatment.
How long do polynucleotides last? A completed course lasts roughly six to nine months, with most patients maintaining the result with a single top-up every four to six months.
