Polynucleotides are making waves in the world of aesthetic medicine — and for good reason. These naturally derived DNA fragments, typically sourced from salmon or trout, are a powerful form of polydeoxyribonucleotide (PDRN) therapy, used to promote deep skin regeneration. Often referred to in popular media as salmon sperm treatments, these injectables are derived from purified salmon DNA, which is highly biocompatible with human tissue.
While the term "salmon sperm" may raise eyebrows outside the clinical setting, in medical aesthetics it simply refers to highly refined DNA-based compounds that work on a cellular level to repair and rejuvenate the skin. The extraction process includes advanced filtration, sterilisation, and quality control to ensure safety, purity, and efficacy. These compounds have been used for decades in medical applications like wound healing, eye surgery, and tissue repair, well before they became known in aesthetics.
Unlike traditional volumising fillers, polynucleotides stimulate fibroblast activity, enhance skin hydration, improve tissue elasticity, and encourage the repair of damaged cells. As demand grows for regenerative, natural-looking outcomes over structural changes, polynucleotides are fast becoming a go-to biostimulator in aesthetic medicine — one that supports long-term skin health instead of temporary volume. For healthcare professionals, this shift represents a new category of treatment that bridges the gap between skin boosters and full volumisers.
The mechanism of action is fundamentally different from HA-based fillers. Polynucleotides don’t simply sit in the skin and attract water; instead, they activate the body’s own regenerative processes. At a cellular level, PNs:
These regenerative injectables support dermal restructuring, making them ideal for patients seeking skin repair, improved tone and texture, and a refreshed appearance without added volume.
Polynucleotides are highly versatile and well-tolerated, making them suitable for use across multiple treatment areas:
Area |
Indication |
Periorbital |
Reduces fine lines and crepiness under the eyes |
Full Face |
Enhances tone, texture, and elasticity |
Neck & Décolletage |
Targets UV-related ageing and horizontal neck lines |
Hands |
Restores skin quality in delicate, visible areas |
Ideal patients include:
These skin repair treatments can be positioned as standalone protocols or integrated into comprehensive aesthetic plans.
A good understanding of tissue anatomy and product behaviour is key to success. Treatment is usually carried out as a course of 3–4 sessions, spaced 2–3 weeks apart.
Treatment Frequency and Patient Education
Consistency matters. For optimal results, ensure patients understand the value of completing the full treatment course. Visible improvements often begin after the second session, with peak results showing at 6–8 weeks.
Common injection techniques:
Combining PNs with Energy-Based Devices
Polynucleotides also integrate well with treatments like microneedling, PRP, radiofrequency, and LED. A staggered or layered treatment plan often improves skin response while minimising downtime.
Educate patients about how regenerative therapies work synergistically with other modalities to support holistic results over time.

Clinical trials and observational studies show positive outcomes in skin elasticity enhancement, hydration, and dermal health following a course of polynucleotide injections. Though large-scale studies are still emerging, existing evidence is encouraging.
Use in Post-Procedure Recovery
Polynucleotides have shown excellent results in accelerating healing following ablative or semi-ablative treatments like fractional laser or RF microneedling. Reduced inflammation and enhanced re-epithelialisation are frequently reported.
Understanding the science is important, but mastering injection technique ensures clinical success. Church Pharmacy’s training covers:

Are polynucleotides made from salmon sperm?
Yes, but clinically speaking, this refers to highly purified DNA extracted from the sperm cells of salmon or trout. These nucleotides are completely safe, biocompatible, and sterilised for use in aesthetic medicine.
How long do polynucleotide results last?
Typically, results develop over several weeks and can last 6–9 months depending on the patient’s skin condition and lifestyle.
Are polynucleotides suitable for sensitive areas?
Yes. They’re especially effective and safe for delicate areas like the under eyes and neck. See product guides for more information.
What’s the difference between polynucleotides and hyaluronic acid (HA) fillers?
Polynucleotides are regenerative and stimulate the body’s natural repair processes, whereas HA fillers add immediate volume. PNs improve skin quality over time, making them ideal for subtle, natural outcomes.
Can they be used with other injectables?
Absolutely. PNs pair well with hyaluronic acid dermal fillers, PRP, microneedling, and other skin boosters.
How long does a polynucleotide treatment take to perform?
Most procedures take around 30–45 minutes, including consultation, preparation, and injection time. Some areas, like the under-eye, may require a shorter session.
How soon can patients see results after starting polynucleotide treatments?
Most patients begin to notice improvement in texture and hydration within 2–3 weeks, with optimal results appearing around 6–8 weeks post-treatment course.
Is there any downtime after treatment?
Downtime is minimal. Some redness or papules at injection sites may last a few hours. Patients should avoid heat, intense exercise, or makeup for 24 hours.
Are polynucleotides suitable for male patients?
Yes. More male patients are seeking skin-quality-focused treatments, and PNs are an excellent option for natural improvement without adding volume.
Are there any specific contraindications for polynucleotide use?
Standard contraindications include pregnancy, breastfeeding, active skin infections, and known hypersensitivity to fish-derived products. Always follow clinical guidance and refer to the product information sheets where possible.
