What are polynucleotides and why use them under the eyes?
Polynucleotides (PNs) are highly purified DNA fragments, most commonly derived from salmon sperm DNA, that work as biostimulators rather than fillers. Injected into the delicate under-eye skin, they stimulate skin repair and collagen production by activating adenosine A2A receptors, gradually improving tissue quality from within. The result is thicker, better-hydrated skin rather than added volume.
The under-eye area is one of the thinnest on the face, which makes it particularly vulnerable to dark circles, puffiness, crepey texture, and fine lines. Polynucleotides address these concerns directly:
- Dark circles caused by vascular show-through improve as skin thickens and light scattering increases
- Puffiness and hollowness respond to improved tissue hydration and elasticity
- Fine lines and crepey texture reduce as collagen remodeling takes hold over several weeks
- Skin thinning reverses gradually with repeated sessions
One key distinction from hyaluronic acid fillers: PNs do not add volume. They regenerate. That makes them a better fit for patients whose primary concern is skin quality rather than structural loss, and it also means the risk of the Tyndall effect (a bluish tint from filler placed too superficially) is essentially eliminated.

| Polynucleotide Clinic | UK | — | Polynucleotide treatments | — | PN-focused specialist care |
Harley Street Dermal is the most credentialed option for patients who want GMC, RCGP, and RCS-certified doctors performing tear trough and under-eye restoration in London. The clinic’s positioning around natural-looking results is backed by a deep specialization in facial injectables.
Perfect Eyes Ltd. stands apart from every other entry on this list because it is run by oculoplastic surgeons. That means the same team can handle both surgical blepharoplasty and non-surgical PN treatment, which matters if your under-eye concerns are complex enough to warrant a surgical consultation alongside injectable options.
The Aesthetics Doctor, led by Dr Ahmed El Muntasar, uses Ameela polynucleotides specifically and has built a reputation for medically led, ethics-first practice. Patients who have had poor experiences with volume-heavy filler elsewhere often find this clinic’s approach a better fit.
Dr Leah Clinics holds CQC registration and won the Safety in Beauty Award in 2024, two markers that carry real weight when you are choosing a clinic for a sensitive area like the periorbital region.
Injectual is the boutique option. Its PN cocktail treatment combines polynucleotides with complementary actives for a more tailored result, and the studio format suits patients who want a focused, unhurried experience rather than a high-volume clinic environment.
Thegoodskinclub, founded by Dr Lydia Pavey at Harley Street and Wallingford in South Oxfordshire, is the strongest choice for patients outside London who want Level 7 qualified medical oversight without traveling into the city for every session. The clinic’s skin rejuvenation treatments cover advanced injectables with transparent pricing and a genuinely personalized approach.
What to expect during your treatment sessions
The consultation
Every reputable clinic starts with a thorough skin assessment before any needle is picked up. The clinician will evaluate the cause of your dark circles (vascular, pigmentary, or structural), assess skin thickness, and discuss your medical history. Contraindications include allergy to fish or salmon DNA, pregnancy, breastfeeding, and active infection or inflammation at the injection site.
The injection procedure
Treatment uses fine needles placed intradermally along the under-eye area. A topical anesthetic cream is typically applied beforehand. The product is distributed evenly across the periorbital region, with the clinician using a tenting technique to keep the PN within the optimal dermal layer for biostimulation. Most sessions take 20–30 minutes.
Most patients need 2–3 initial sessions spaced roughly 3 weeks apart. A third session is often added for patients with more pronounced wrinkling after the second.
Post-treatment care
- Avoid rubbing or pressing the treated area for 24 hours
- Skip intense exercise and saunas for 48 hours
- Stay out of direct sun and apply SPF daily
- Mild swelling and redness typically resolve within 24–48 hours
- Bruising is possible but usually minor given the fine needle gauge used
Pro Tip: Ask your clinician specifically whether they use a 30G or finer needle for the periorbital area. Finer gauge needles reduce bruising risk in this thin-skinned zone, and a clinician who can answer that question confidently is one who has done this procedure many times.
What results can you realistically expect?
Visible improvements typically begin a few weeks after the first session, with the most pronounced changes appearing at the 3-month mark following two treatment sessions. A prospective observational study of 42 patients receiving intradermal PN injections found significant improvement in lower eyelid and crow’s feet scores at all follow-up points, with peak satisfaction at 3 months. By 6 months, scores remained improved over baseline, though slightly below the 3-month peak, which supports maintenance treatment at or before that point.
Compared to hyaluronic acid fillers, PNs outperform on skin texture and wrinkle depth reduction in the periorbital region, while fillers edge ahead on immediate volumization. The two approaches are not mutually exclusive.
Where PNs work best:
- Vascular dark circles (bluish tint from blood vessels showing through thin skin)
- Crepey, dehydrated under-eye skin
- Fine lines and early periorbital wrinkling
Where PNs have limits:
- Pigmentary dark circles caused by melanin excess respond poorly to PNs alone
- Fat pad displacement or significant hollowing usually requires a structural filler or surgical consultation
- Severe laxity may need combination therapy with Morpheus8 or thread lifts
For patients with mixed causes, clinicians at practices like Perfect Eyes Ltd. or Dr Leah Clinics often combine PNs with complementary treatments to address multiple factors simultaneously.
How to choose the right clinic and provider in the UK
The under-eye area is unforgiving. A poorly placed injection here can cause swelling, asymmetry, or visible product. These are the questions worth asking before you book:
- What are your qualifications? Look for GMC registration, Level 7 aesthetic qualifications, or surgical credentials (FRCS for oculoplastic surgeons). CQC registration is an additional marker of clinical governance.
- How many PN under-eye treatments have you performed? Experience in this specific area matters more than general injectable experience.
- Which product do you use and why? Named products like Ameela, Pluryal Silk, or Rejuran each have different concentrations and formulations. A clinician who can explain their choice is one who understands the science.
- Can I see before-and-after photos of your own patients? Stock imagery is not evidence. Real patient photos from the actual clinician’s work are.
- What is your aftercare policy if I have a complication? Any reputable clinic will have a clear protocol.
Red flags to walk away from: clinics that cannot name the product they use, providers without verifiable medical registration, pricing that seems too low to cover a proper consultation, and any clinic that promises dramatic results after a single session.
Pricing transparency matters too. UK treatment costs range from £200 to £1,000 per session, so a clinic that publishes clear pricing and explains what is included in a package is one that respects your ability to make an informed decision.
