Under-eye Restoration with Polynucleotides
Prices from £375
Refresh under-eye and improve skin
Polynucleotides are a regenerative injectable that refreshes the delicate under-eye area and improves skin quality rather than adding volume. It stimulates collagen, boosts hydration and helps brighten the appearance of dark circles and fine creasing.
This treatment is especially suited to eyes that look tired or crepey, or where thin skin casts a shadow. Polynucleotides can also be used on other areas, but under-eye is the most popular starting point.
Most people complete a series of three sessions spaced two to four weeks apart. Results continue to develop after each visit and often last six to twelve months before a simple maintenance session.
Is this treatment for me?
If you are noticing:
- Dark circles linked to thin or crepey under-eye skin
- Fine lines, texture changes or a persistent tired look
- Mild puffiness rather than significant fat prolapse
What can I expect?
- Mild puffiness for 24 to 72 hours is common, then it settles
- A course of three sessions spaced 2 to 4 weeks apart is typical
- Brighter, smoother under-eyes that look rested and natural, often lasting 6 to 12 months
Our Method
Step one
Comprehensive Consultation
In a comprehensive consultation, we’ll discuss your medical and cosmetic history in detail and invite you to share ideas, goals and any concerns.
We’ll examine your skin at rest and with expression to understand how lines form. With your consent, we take photographs from several angles, including profile, to guide planning and track results.
Treatment Planning
Your unique facial anatomy informs a personalised plan for natural-looking results. There is no one-size-fits-all option when it comes to the face.
We explain how your anatomy guides technique and approach, and why specific areas may benefit most. The plan is bespoke and aligned with your features and goals.
Preparation & Final Checks
Before any injections, your skin is cleansed with a gentle, hypoallergenic cleanser. (Arriving without makeup helps keep things efficient.)
This step ensures a hygienic and safe procedure in a calm setting. We confirm the plan with you and answer any final questions.
Treatment & Results
The injecting stage typically lasts about ten minutes. Most people find it comfortable, though it can feel like a brief sharp scratch.
Small red bumps at injection sites usually settle within 15 minutes. Initial smoothing appears after about one week, with full results at two weeks.
As a Blackheath Clinic patient, you’ll also receive a tailored medical-grade skincare plan to support and maintain your results, guided by your complimentary Zemits VeraFace 12-factor AI skin analysis.

Our Patient Review

I was understandably very worried and was able to book an appointment within just a couple of hours. From the moment we met him, Dr Mac Sweeney was kind, reassuring, professional and genuinely caring. He took the time to listen, explained everything clearly, and made us feel that my husband was in very safe hands.
What impressed me most was that his care did not stop when we left the consultation. He followed up on several occasions to check on my husband's progress, prescribed more medicine and even went out of his way to provide a letter for our insurance company, which was incredibly helpful.
In a world where good service can sometimes feel hard to find, Dr Mac Sweeney demonstrated a level of compassion and personal attention that was truly exceptional. The fee was also very reasonable, especially given the time, care and support we received.
I would wholeheartedly recommend Dr Mac Sweeney to anyone needing medical assistance and will always be grateful for the kindness he showed to both of us. If I lived in London I would most certainly subscribe to his membership scheme so he could deal with all my family's medical needs.


The clinic has a friendly and relaxed atmosphere, with a fresh, calming scent that immediately creates a welcoming environment. Everything was explained clearly and professionally, making the whole experience completely stress-free.
I particularly appreciated the expert advice and felt comfortable throughout. I would highly recommend The Blackheath Clinic to anyone looking for a professional, patient-focused service.


As I entered the tastefully curated space, I encountered one of the rarest of things: a polite, smiling and genuinely welcoming receptionist. In fact, she was so warm and courteous that I briefly wondered whether I had wandered into an upmarket spa by mistake.
Then I met Dr Sweeney. He was charming, courteous, friendly and thoroughly professional, with the kind of bedside manner that reminds you what general practice can be at its best: attentive, humane and quietly confident. He came across as someone who takes real pride in his work and genuinely cares for his patients.
The whole experience felt like stepping back into a time when patients were warmly received and doctors truly doctored. As I was leaving, Dr Sweeney mentioned that he was off on a home visit. A GP doing a home visit in 2026? I was so astonished I nearly needed examining all over again.
Join this practice quickly before word gets out and the list fills up. This is care delivered by people who genuinely care, and that feels all too rare these days

I had lip filler and RRS Long Lasting skin boosters, and she took the time to explain everything clearly, answer all my questions, and ensure I felt confident about the treatments. Her attention to detail and gentle approach really stood out, and I couldn’t be happier with the results.
Dr Micha Plugaru truly combines expertise with a warm, personal touch. I would highly recommend her to anyone considering aesthetic treatments — you’re in the safest and most caring hands.
