Polynucleotides vs Dermal Fillers: The 2026 Decision Guide
For a decade, dermal fillers were the default answer to facial ageing. That has changed. UK search interest in regenerative treatments like polynucleotides has surged past traditional fillers, and the clients walking into our Cardiff clinic increasingly ask for skin that looks healthier, not bigger. Here is the honest comparison.
Two completely different jobs
Dermal fillers are hyaluronic acid gels that restore lost volume and structure. They are the right tool when the problem is genuinely volumetric: hollow cheeks, a recessed chin, deep nasolabial folds caused by descent of the midface.
Polynucleotides do not add volume at all. They are purified DNA fragments that switch on your skin's own repair machinery, increasing collagen and elastin production, improving hydration, and reducing inflammation. The result is skin that is measurably thicker, firmer and brighter, achieved by regeneration rather than augmentation.
When fillers are the right answer
- Genuine volume loss in the cheeks, temples or chin
- Structural balancing of the jawline or profile
- Deep static folds that need physical support
When polynucleotides are the right answer
- Crepey, thinning or sun-damaged skin
- Dark circles and under-eye crepiness, where filler often looks puffy
- Early jowling where skin quality, not volume, is the issue
- Anyone worried about looking "done" — polynucleotides cannot overfill a face
The "filler fatigue" factor
A growing number of our clients come to us to move away from repeated filler top-ups. Over-filled faces are now one of the most common concerns we correct. Regenerative treatments offer a different bargain: slower, subtler, but cumulative. Each course leaves your skin structurally better than before, which is why we built our whole philosophy around regenerative aesthetics.
Frequently asked questions
Which lasts longer?
Fillers last 9 to 18 months depending on the area. Polynucleotide results build over a course and the new collagen is yours to keep, with maintenance sessions every six to nine months.
Can I combine them?
Yes, and the combination is often ideal: polynucleotides to restore skin quality, with a precise, conservative amount of filler only where true volume is missing.
Which is safer?
Both are safe in medical hands. Polynucleotides carry a lower risk profile overall because they are not volumising and cannot cause vascular occlusion in the same way.
The right plan starts with an honest assessment. Book a consultation at The Enchara in Cardiff and we will tell you plainly which approach your face actually needs — including when the answer is neither.
