Polynucleotide Treatment
Polynucleotides are an advanced regenerative injectable treatment designed to improve skin quality at a cellular level. Rather than adding volume or altering facial shape, polynucleotides work by stimulating the skin’s natural repair processes, helping to restore strength, elasticity and hydration from within.
This treatment is particularly effective in delicate areas such as the under-eye, where the skin is thin and prone to fine creasing, shadowing and a tired appearance. By encouraging collagen production and improving micro-circulation, polynucleotides help to smooth fine lines, brighten dark circles and improve overall skin texture. The result is a more refreshed, rested look, without heaviness or swelling.
While the under-eye area is the most popular starting point, polynucleotides can also be used on the face, neck, décolletage and hands to improve skin quality in areas showing early signs of ageing or loss of vitality.
For optimal results, a course of three treatments is usually recommended, spaced two to four weeks apart. Improvements develop gradually after each session, with results typically lasting between six and twelve months. A single maintenance treatment can then be performed to prolong and sustain the benefits.
At The Blackheath Clinic, all polynucleotide treatments are performed by experienced medical professionals following a detailed consultation to ensure the treatment is tailored to your individual skin needs and goals.

Our Method
Step one
Comprehensive Consultation
Your journey begins with a detailed medical and aesthetic consultation. We take the time to understand your medical history, skin concerns and treatment goals, ensuring polynucleotide therapy is clinically appropriate for you.
Your skin is carefully assessed to evaluate quality, texture and areas that may benefit most from regenerative treatment. With your consent, medical photographs may be taken to support treatment planning and accurately track progress over time.
Treatment Planning
Polynucleotide treatment is tailored to your individual skin needs rather than a one-size-fits-all approach. Your clinician will create a bespoke plan based on the areas being treated, skin condition and desired outcomes.
We will explain how polynucleotides work, which areas are likely to benefit most, and how the treatment will be delivered to achieve natural, balanced results aligned with your goals.
Preparation & Final Checks
On the day of treatment, the skin is cleansed thoroughly using a gentle, medical-grade cleanser to ensure a hygienic and safe procedure. Arriving without makeup can help streamline this step.
Before proceeding, we reconfirm your treatment plan, answer any final questions and ensure you are comfortable to continue.
Treatment & Results
The treatment itself typically takes 10–15 minutes, depending on the areas treated. Most patients find the procedure well tolerated, experiencing only brief, mild discomfort during injection.
Small bumps or mild redness at the injection sites are common and usually settle within a short period. Improvements in skin quality develop gradually over the following weeks, with optimal results seen after completion of the recommended treatment course.
As a patient of The Blackheath Clinic, you will also receive personalised guidance on medical-grade skincare to support and prolong your results, informed 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.
