Polynucleotide treatment is a regenerative injectable that improves skin quality, hydration and elasticity by stimulating the skin’s own repair processes. Unlike dermal filler, it adds no volume. Instead, it helps improve fine lines, crepey skin and dark circles by making the skin itself healthier.
We offer polynucleotide treatment at our Tunbridge Wells clinic on the High Street, serving patients across west Kent. This guide covers the benefits, who it suits, recovery and what to expect from a course of treatment.
Polynucleotides are a bio-revitalising treatment, meaning they revive the skin from within rather than adding anything to it. Once injected, they stimulate fibroblasts, the cells that produce collagen and elastin, and support the repair of damaged skin.
Over the following weeks, skin becomes firmer, more hydrated and healthier. Nothing is filled or plumped; the change is in the quality of the skin itself.
Polynucleotides also combine well with anti-wrinkle injections and dermal filler for tired eyes or an overall refreshed appearance.
Polynucleotides are versatile and can be used on:
Polynucleotides suit most adults, and they’re particularly well matched to:
They’re often used alongside other treatments: polynucleotides improve the skin itself, while filler and anti-wrinkle injections address structure and movement.
Polynucleotides may not be suitable if you have a fish allergy, are pregnant or breastfeeding, or have an active skin infection in the treatment area. We’ll check this at your consultation.
Our Tunbridge Wells clinic is at 38 High Street, Tunbridge Wells, TN1 1XF. We see patients from across west Kent, including Sevenoaks, Tonbridge, Southborough, Pembury, Paddock Wood and Crowborough, without the trip into London.
Every new patient has a free one-to-one consultation before any treatment is booked. Polynucleotides suit some concerns very well and others not at all, and the consultation is where we find out which applies to you. If a different treatment would serve you better, we’ll tell you.
All treatments are carried out by our medically qualified doctors and nurses.
Polynucleotide treatment in our Kent clinic starts from £99 per session, or from £299 for a course of three, depending on the product. Payment plans are available.

While your dedicated practitioner will always be there to answer every last one of your questions in person, this section is here to give you a bit of a head start on some of our most common queries.
Most people need a course of three, spaced two to four weeks apart. After that, maintenance every six to twelve months keeps the result. Some concerns need fewer sessions and some more, which we'll assess at consultation.
Filler occupies space and creates an immediate structural change -a fuller cheek, a defined jawline.. Polynucleotides add no volume at all. They improve the quality, thickness and hydration of the skin itself, and the change appears gradually over several weeks. Many patients have both, treating different things.
Small visible bumps at each injection point are normal and usually settle within a few hours. Expect some redness, mild swelling and possibly bruising, particularly around the eyes where the skin is thinnest. Everything typically resolves within a few days.
Anyone with a fish or shellfish allergy, since the product is salmon-derived. We also avoid treating during pregnancy or breastfeeding, over an active skin infection or cold sore, or where there's an untreated inflammatory or autoimmune skin condition. Tell us about any allergies at consultation.
