The regenerative injectable for skin quality
If you have been researching treatments that improve skin quality rather than simply add volume, you will likely have come across polynucleotides.
At Newcastle Skin Clinic, polynucleotides sit firmly within our Skin Regeneration pillar. They are not fillers. They are not skin boosters in the traditional sense. They are regenerative injectables designed to improve the health and function of your skin at a cellular level.
This is about repairing, strengthening and restoring. Not masking.
What are polynucleotides?
Polynucleotides are highly purified DNA fragments, typically derived from salmon DNA due to its strong biocompatibility with human tissue, as featured in Byrdie. When injected into the skin, they stimulate repair and regeneration within the extracellular matrix.
In simple terms, they encourage your skin to behave like healthier, younger skin.
Rather than filling lines or changing facial structure, polynucleotides improve:
- Skin texture
- Elasticity
- Hydration
- Crepey or thinning skin
- Overall skin resilience
They work particularly well in delicate areas where traditional fillers may not be appropriate.
How do polynucleotides support DNA repair?
One of the most powerful aspects of polynucleotides is their role in supporting cellular repair.
As we age, our skin’s ability to repair DNA damage slows down. Environmental stress, UV exposure, inflammation and hormonal changes all contribute to this decline. Polynucleotides help to:
- Stimulate fibroblast activity
- Encourage collagen and elastin production
- Improve microcirculation
- Support tissue regeneration
The result is stronger, healthier skin that functions better over time.
This is regenerative medicine applied to aesthetics. It is subtle, intelligent and cumulative.
Reducing inflammation and improving skin health
Chronic low-level inflammation is one of the biggest drivers of visible ageing. Polynucleotides have anti-inflammatory properties, helping to calm reactive or stressed skin. They can improve redness, sensitivity and compromised barrier function, making them particularly useful for:
- Thin or fragile skin
- Post-procedure recovery
- Hormonal skin changes
- Early skin laxity
At Newcastle Skin Clinic, we often use polynucleotide treatment as part of a wider treatment strategy focused on long-term skin quality rather than quick fixes.
Polynucleotides for under-eyes
The under-eye area is one of the most requested treatment zones in clinic.
It is also one of the most delicate. The skin here is thin, prone to creasing and can look hollow or tired as collagen declines.
Polynucleotides are ideal for this area because they:
- Improve skin thickness and elasticity
- Reduce crepey texture
- Support better hydration
- Improve overall under-eye quality
They do not add volume in the way tear trough filler does. Instead, they improve the skin itself. For many patients, this creates a fresher, brighter appearance without heaviness.
A full consultation is essential to determine whether polynucleotides, tear trough filler, or a combined approach is most appropriate.
What is the treatment plan?
Polynucleotides are typically delivered as a course.
Most patients require:
- 2 to 3 sessions
- Spaced 2 to 4 weeks apart
- With maintenance every 6 to 9 months, depending on skin condition
Results build gradually as collagen regeneration takes place. You may notice improved hydration and glow early on, with texture and firmness improving over the following weeks.
This is not an overnight transformation. It is a progressive improvement in skin health.
Are polynucleotides right for you?
Polynucleotides are particularly suitable if you:
- Are noticing early signs of ageing
- Have thin or crepey under-eye skin
- Want skin improvement without added volume
- Prefer a regenerative approach to aesthetics
At Newcastle Skin Clinic, all injectable treatments are carried out following a detailed medical consultation. Our approach is conservative, evidence-led and focused on natural outcomes.
If you are curious about polynucleotides and whether they fit into your skin regeneration plan, we would be happy to guide you.
