The Complete Practitioner's Guide to Polynucleotides

Polynucleotides have become one of the most talked-about treatments in aesthetics — and for good reason. But with so many products entering the market, how do you know what to stock, what to use, and how to get the best results for your clients?

Polynucleotides — also known as PDRN (Polydeoxyribonucleotide) — are bio-stimulating injectables derived from purified salmon or trout DNA. Unlike traditional dermal fillers that add volume, polynucleotides work by stimulating the body's own regenerative processes, triggering fibroblast activation and collagen synthesis from within.

How do Polynucleotides Work?

When injected into the skin, PDRN molecules bind to adenosine receptors, stimulating a cascade of cellular repair processes. This triggers the production of collagen and elastin, improves tissue hydration at a deep level, and accelerates the turnover of damaged cells. The result is skin that genuinely functions better — not just skin that looks temporarily plumped.

The key difference from HA fillers is that polynucleotides deliver progressive improvement over 4–8 weeks as the biological cascade continues to unfold. Patients often describe looking "better and better" in the weeks following treatment, rather than experiencing the immediate-then-gradual-decline arc typical of volumising fillers.

Key Treatment Areas

Polynucleotides can be used across a wide range of treatment zones, making them one of the most versatile products in your kit:

Treatment Protocol: What to Expect

Initial Course

Most patients require an initial course of 3–4 sessions spaced 2–4 weeks apart. This loading phase allows the regenerative process to build momentum. Results begin to appear from the second session onwards, with peak results typically visible 4–6 weeks after the final treatment in the initial course.

Maintenance

After the initial course, most patients maintain results with a single treatment every 3–6 months. This makes polynucleotide treatments an excellent foundation for a clinic membership or loyalty programme — patients are highly likely to return once they've experienced the quality of results.

Why Stock PN Boosters?

From a business perspective, polynucleotides represent one of the strongest opportunities in aesthetics right now. Patient demand is growing faster than supply in many clinics, average treatment values are strong, and the repeat appointment rate is exceptionally high. Practitioners who invest in becoming PN specialists now are positioning themselves at the forefront of where the industry is heading.

At MBE Aesthetics, we stock AMI Eyes — one of the most clinically trusted PN formulations available — alongside our full range of skin boosters designed to complement and enhance polynucleotide treatment protocols.
