The Ultimate Guide to Polynucleotides for Skin Health and Rejuvenation
Are you interested in the latest Skin Booster Treatments that everyone is talking about? As a GP and aesthetics doctor based in Newcastle, I understand that healthy, youthful skin is more than just cosmetic—it’s often a reflection of our overall health and well-being. Polynucleotide treatments are one of the most exciting developments in regenerative aesthetics, offering profound skin revitalisation with a scientific foundation rooted in medical research.
In this ultimate guide, I will walk you through everything you need to know about polynucleotides: what they are, how they work, their benefits, safety profile, and why more patients are turning to this advanced injectable treatment for skin regeneration.

What Are Polynucleotides?
Polynucleotides are biocompatible, injectable gels derived from purified DNA fragments, typically sourced from salmon or trout sperm. These molecules are the building blocks of DNA and RNA and are used to stimulate cell repair, boost hydration, and trigger collagen production naturally within the skin.
Polynucleotides fall under the category of biostimulators. They don’t simply “fill” areas like dermal fillers; they help the skin regenerate and repair itself over time.
Polynucleotide injections are sometimes referred to as “PN” or “PDRN” (polydeoxyribonucleotide), depending on their molecular composition and application. While they are a relatively new concept in aesthetic clinics across the UK, they have been widely used in regenerative medicine in Europe and Asia for decades.
How Do Polynucleotides Work?
Polynucleotides work by stimulating fibroblast activity in the skin. Fibroblasts are the cells responsible for collagen and elastin production, which are vital for skin firmness and elasticity.
When injected, polynucleotides:
- Hydrate the skin by attracting water molecules (thanks to their high affinity to bind with water)
- Promote cell turnover and tissue repair
- Reduces inflammation and oxidative stress
- Improves skin elasticity and tone
- Enhance microcirculation, aiding nutrient and oxygen delivery to skin cells
These processes help reverse signs of ageing, especially in delicate areas like the under-eyes, neck, and even acne-scarred regions.
Clinical Evidence and Scientific Backing
Polynucleotide-based therapies have been used for over 30 years in medicine, particularly in wound healing, ophthalmology, and orthopaedics. Their use in aesthetics is supported by clinical studies:
- A 2020 study in the Journal of Cosmetic Dermatology found that polynucleotide treatments improved dermal density and elasticity in photoaged skin (source).
- Research published in Plastic and Reconstructive Surgery highlighted improvements in skin texture and hydration after polynucleotide mesotherapy.
- A clinical trial published in the Annals of Dermatology (2019) showed measurable improvement in skin elasticity and reduction in melanin levels after a course of polynucleotide injections.
These treatments are CE-marked for safety in the UK and have minimal downtime compared to other skin rejuvenation methods.
What Are the Benefits?
Polynucleotide treatments offer a range of benefits:
- Enhanced skin texture and tone
- Improved hydration and radiance
- Softer, fine lines and wrinkles
- Effective under-eye rejuvenation (tear troughs)
- Long-lasting collagen stimulation
- Treatment of dullness, pigmentation, and early laxity
- Improved appearance of acne scarring
- Can be used on the face, neck, hands, and décolletage
Because they work gradually, results develop over weeks, providing a subtle yet noticeable transformation.
What Areas Can Be Treated?
- Under-eyes (tear troughs): A popular treatment for dark circles and crepey skin.
- Full face: For overall skin improvement and glow.
- Neck and décolletage: Targets crepey skin and early sagging.
- Hands: Rejuvenates thin or ageing skin.
- Acne-scarred areas: Enhances skin regeneration and tissue healing.
- Stretch marks and surgical scars (off-label use): Evidence suggests improvement in scar appearance.

What to Expect During Treatment
- Consultation: At your initial appointment, I will assess your skin and discuss your goals.
- Procedure: Small amounts of polynucleotide gel are injected into the target areas using a fine needle.
- Comfort: The treatment is usually well-tolerated. A topical anaesthetic can be applied for added comfort.
- Time: The procedure takes around 30 minutes.
- Downtime: Minimal. You may experience slight swelling or redness, which typically subsides within 24-48 hours.
- Aftercare: Avoid makeup for 24 hours and vigorous exercise for a couple of days.
- Results: Noticeable improvement in skin texture and hydration from 2-4 weeks, with continued collagen production over 2-3 months.
Who Is It For?
Polynucleotide injections are suitable for a wide range of individuals:
- Patients in their 30s-50s looking to combat early signs of ageing
- Individuals with sensitive or reactive skin seeking gentle biostimulation
- Those recovering from acne or with mild scarring
- People who want to avoid the “filled” look
- Postpartum or perimenopausal women who are experiencing skin changes
Are Polynucleotides Safe?
Yes, polynucleotide treatments have an excellent safety profile:
- CE-marked in Europe and approved for clinical use
- Non-crosslinked and non-immunogenic, meaning low risk of adverse reactions
- Sourced from sterile, pharmaceutical-grade DNA (often fish-based)
- Patients with known allergies to fish or seafood should not undergo this treatment.
Polynucleotide Treatment FAQs
Is Polynucleotides treatment safe?
Yes. Polynucleotides are CE-marked and well-tolerated. They are biocompatible and non-immunogenic.
How many Polynucleotide treatments will I need?

Can polynucleotides be combined with other treatments?
Yes. They work well alongside Profhilo, PRP, Radiofrequency microneedling, and even Botox.
Are the results permanent?
No. Like all regenerative treatments, maintenance sessions every 6-12 months are advised.
Do Polynucleotide injections hurt?
Most patients find the procedure tolerable. A numbing cream can be applied to reduce discomfort.
