Polynucleotides have become the most talked-about injectable treatment in aesthetics — and clinics across Birmingham are seeing significant demand from clients who have heard about them online and want to understand how they compare to the fillers they already know. At DZ Beauty in Sutton Coldfield, we offer polynucleotide treatments alongside our full skin booster range, and the question we are most frequently asked is: what is the difference, and which one do I need?
What Are Polynucleotides?
Polynucleotides (PNs) are long chains of nucleotides — the building blocks of DNA — derived from purified salmon or trout DNA. When injected into the skin, they stimulate fibroblast activity, which increases the production of collagen, elastin, and hyaluronic acid. They also have anti-inflammatory properties and support tissue repair at a cellular level. The effect is a genuine improvement in skin quality — texture, hydration, firmness, and luminosity — rather than a volumising or sculpting result.
What Are Fillers?
Dermal fillers are injectable gels — most commonly hyaluronic acid-based — that physically add volume and structure to specific areas of the face. They are used to restore volume loss, define contours, plump lips, and fill deep static lines. They produce an immediate, structural result that changes the appearance of the face by adding substance where volume has been lost.
The Key Difference: Quality vs Volume
This is the essential distinction. Polynucleotides improve skin quality from within — they make your existing skin better, healthier, and more youthful-looking. Fillers change facial structure by adding volume. Both are valuable, but they solve different problems. A client whose main concern is dull, crepey, dehydrated skin with fine lines benefits most from polynucleotides. A client who has lost significant cheek volume or has deep nasolabial folds benefits most from fillers.
Who Should Choose Polynucleotides?
- Clients wanting to improve overall skin quality, texture, and radiance
- Those with fine lines and early skin laxity rather than significant volume loss
- Clients with under-eye concerns — tear trough area, dark circles, and crepey skin
- Those who have been told they need "prevention" rather than "correction"
- Clients who want a natural result with no visible change to facial structure
- Darker skin tones looking for a safe, non-laser treatment for skin improvement
Can You Have Both?
Yes — and the combination is increasingly popular among our Sutton Coldfield clients. Fillers restore volume and structure; polynucleotides improve the quality of the skin overlying those structures. Used together, they address both the architecture of the face and the quality of the skin surface, producing a comprehensive result that looks genuinely healthy and refreshed rather than merely filled.
