Polynucleotides are increasingly recognised as one of the most advanced regenerative skin treatments in modern aesthetic medicine. Often misunderstood as a filler or dismissed as a passing trend, polynucleotides offer something fundamentally different: a refined, science-led approach to improving skin quality, resilience, and long-term health.
In an industry where new treatments appear constantly, it’s understandable that many people assume polynucleotides are simply another injectable trend. In reality, polynucleotides are neither a filler nor a passing aesthetic fashion. They are a regenerative treatment, designed to improve skin health at a cellular level.
At Refine Clinic, we focus on treatments that support the skin long-term, not quick fixes that mask underlying issues. Polynucleotides fit firmly into that philosophy.
What are polynucleotides?
Polynucleotides are purified DNA fragments used in aesthetic medicine to support skin regeneration and repair. They work by activating the skin’s own healing mechanisms, making them a cornerstone treatment for patients seeking natural skin rejuvenation without volume or facial change.
Polynucleotides are purified fragments of DNA that work by stimulating the skin’s natural repair processes. When injected into the skin, they act as biostimulators, encouraging cell regeneration, improving hydration, and supporting collagen and elastin production.
Rather than adding volume or altering facial structure, polynucleotides help the skin function more effectively on its own.

A common misconception is that polynucleotides behave like dermal fillers. They do not. This distinction is essential for patients considering regenerative aesthetic treatments.
One of the most important distinctions to understand is that polynucleotides do not add volume.
Unlike dermal fillers, which are designed to:
- Restore or create volume
- Reshape facial contours
- Fill lines or folds
Polynucleotides work differently. They:
- Improve skin quality
- Enhance elasticity and firmness
- Support hydration and resilience
- Strengthen the skin barrier
The result is healthier, more robust skin – not a change in facial shape or expression.
Polynucleotides are not a trend
Although polynucleotides have gained attention in aesthetic medicine in recent years, their medical use is long established. Widely used in regenerative medicine for tissue repair, wound healing, and anti-inflammatory support, their introduction into aesthetics reflects a broader shift toward natural, regenerative treatments that prioritise skin health over overcorrection.
We don’t follow trends. We choose scientifically supported treatments that deliver subtle, gradual and natural-looking results.
How polynucleotides work
Polynucleotides function as biostimulators, improving the biological environment of the skin rather than altering its structure. This allows the skin to regenerate gradually and naturally.
Polynucleotides support the skin in several key ways:
- Stimulating fibroblast activity to improve collagen and elastin
- Enhancing skin hydration at a deep level
- Reducing inflammation within the skin
- Improving texture, tone, and overall skin quality
Results develop progressively over weeks, as the skin responds and regenerates. This makes polynucleotides particularly appealing to patients who value subtle, long-term improvement.

Who are polynucleotides suitable for?
Polynucleotides are particularly suited to patients who value refined, understated results and prioritise long-term skin health over instant cosmetic change.
Polynucleotides are suitable for a wide range of patients, particularly those who:
- Want to improve skin quality rather than volume
- Prefer natural-looking results
- Have thin, delicate or crepey skin
- Are concerned about early signs of ageing
- Have tired, dehydrated or stressed skin
They are especially effective in areas where fillers may not be appropriate, such as:
- Under the eyes
- Neck
- Décolletage
- Perioral area
Why timing and course matter
Polynucleotides are most effective when administered as a course of treatments, with results developing gradually as skin quality improves over time. Beginning treatment during the cooler months allows the skin to regenerate with less UV stress, making it an ideal choice for strengthening and refining the skin ahead of spring and summer.
What polynucleotides will - and won’t - do
They will:
- Improve skin texture and elasticity
- Increase hydration and resilience
- Support long-term skin health
- Strengthen compromised or ageing skin
They won’t:
- Add volume
- Replace dermal fillers or surgery
- Deliver instant results
- Dramatically lift sagging skin
Understanding these expectations is key to achieving satisfaction with treatment outcomes.
Why timing and course matter
Like most regenerative skin treatments, polynucleotides deliver optimal results when administered as a course of treatments. Improvement develops gradually as skin quality strengthens over time.
Polynucleotides are most effective when delivered as a course of treatments, allowing cumulative improvement over time. They are ideal to start during the cooler months, when the skin is under less UV stress and can regenerate optimally.
This makes them an excellent choice for patients looking to improve skin quality ahead of spring and summer.
At Refine Clinic, polynucleotides are delivered as part of a bespoke, consultation-led treatment plan. Every patient’s skin is assessed individually to ensure suitability, safety, and optimal outcomes.
At Refine Clinic, polynucleotides are never offered as a one-size-fits-all solution. A detailed consultation ensures the treatment is appropriate for your skin type, concerns, and goals.
Our focus is not on trends, but on treatments that respect the skin and deliver meaningful, lasting improvement.
Polynucleotides are not a filler, and they are not a trend. They represent a sophisticated, regenerative approach to skin rejuvenation - one that enhances skin quality from within while preserving natural facial integrity.
They are a regenerative treatment designed to support healthier, stronger, and more resilient skin.
For patients seeking natural results, improved skin quality, and a long-term approach to ageing well, polynucleotides offer a scientifically grounded and thoughtful solution.
If you are considering polynucleotides and would like expert advice tailored to your skin, we invite you to book a consultation at Refine Clinic.
Our experienced doctor, Dr. Natalia Bratu, will guide you through whether polynucleotides are suitable for you and design a treatment plan focused on refined, natural results.
