The Science of Skin Regeneration: Why Polynucleotides Are the Future of Aesthetics

Skin Treatments & Rejuvenation

If you follow aesthetic trends or speak to skin health professionals, you’ve likely heard the phrase on everyone’s lips: Polynucleotides.

While dermal fillers and traditional anti-wrinkle injections have held the spotlight for years, the world of medical aesthetics has shifted toward regenerative medicine—treatments designed to stimulate your body’s natural biological repair mechanisms rather than just mask the signs of ageing.

If you’re looking for a treatment that improves skin texture, firmness, and overall health at a cellular level, polynucleotides might be exactly what your skin routine has been missing.

Here is everything you need to know about what polynucleotides are, how they work, and why they are revolutionizing clinical skincare.

What Are Polynucleotides?

Polynucleotides are biological molecules made up of filtered, purified chains of nucleotides—the essential building blocks of DNA and RNA. Derived from salmon or trout DNA (which closely mirrors human DNA), these molecules are thoroughly purified, sterilized, and formulated into an injectable gel.

Unlike dermal fillers, which add physical volume under the skin, or anti-wrinkle injections, which temporarily relax facial muscles, polynucleotides act as biostimulators.

When injected into the skin, they communicate directly with your cells, signalling them to repair, hydrate, and regenerate from deep within the dermal layers.

How Do They Work?

Think of polynucleotides as a high-performance “reset button” for your skin cells. They work through three core mechanisms:

Fibroblast Activation: They stimulate fibroblasts—the primary cells responsible for producing collagen and elastin. This helps restore natural skin density, springiness, and elasticity.
Deep Cellular Hydration: Polynucleotide chains have an extraordinary ability to bind and lock water within the tissues, creating long-lasting, deep-level hydration that topicals simply can’t reach.
Wound Healing & Anti-Inflammatory Effects: They scavenger free radicals, reduce inflammation, and promote micro-vascular circulation, helping damaged or stressed skin heal more effectively.

The Key Benefits of Polynucleotide Treatments

Polynucleotides are extremely versatile and offer a wide range of clinically proven benefits:

1. Rejuvenation for Delicate Areas (Like the Under-Eyes)
Finding safe, effective treatments for the delicate skin around the eyes can be tricky. Traditional dermal fillers can sometimes lead to fluid retention or swelling in the tear trough area. Polynucleotides, however, do not absorb excess water in the same way—making them ideal for reducing dark circles, smoothing fine crepey skin, and firming under-eye hollows.
2. Improved Collagen Production & Skin Density
As we age, collagen production drops significantly. By re-energizing your cells, polynucleotides boost collagen and elastin synthesis over time. This leads to noticeably firmer, tighter skin with a visible reduction in fine lines and wrinkles.
3. Reduced Inflammation & Redness
Thanks to their anti-inflammatory properties, polynucleotides help soothe calm reactive skin conditions, including rosacea, hyperpigmentation, and post-acne scarring. They restore the skin’s natural barrier function, leaving your complexion calmer and more balanced.
4. Natural-Looking, Gradual Results
Because polynucleotides work by enhancing your body’s natural cellular processes, the results develop gracefully over a few weeks. You won’t look “overfilled” or altered—just refreshed, radiant, and healthier.

Where Can Polynucleotides Be Used?

One of the greatest advantages of polynucleotides is their adaptability across various areas of the face and body:

Under-Eye Area: Dark circles, hollows, and fine lines (crow’s feet)
Full Face: Overall skin texture, elasticity loss, and fine wrinkles
Neck & Décolletage: Crepey skin and sun-damaged chest areas
Hands: Restoring skin thickness and hydration to aging hands
Scalp: Stimulating hair follicles for thinning hair

What to Expect During Treatment

Polynucleotide therapy typically involves a series of small, shallow injections into the target area using an ultra-fine needle.

Downtime: Minimal. You may experience slight redness, small localized bumps, or mild bruising at the injection sites, which usually settle within 24 to 48 hours.
Treatment Plan: For optimal, long-lasting results, we generally recommend a initial protocol of 2 to 3 sessions, spaced roughly 2 to 4 weeks apart, followed by a maintenance treatment every 6 to 9 months.
Results Timeline: Initial hydration benefits appear within a few days, with structural collagen synthesis building over 1 to 3 months.

Is Polynucleotide Therapy Right for You?

Polynucleotide treatments are suitable for almost all skin types and ages. Whether you want to proactively prevent early signs of ageing in your late 20s and 30s, or restore skin quality and density in your 40s, 50s, and beyond, this regenerative therapy offers a safe, evidence-based solution.

Note: Because the product is derived from fish DNA, it is not suitable for individuals with a known fish allergy or those following a strict vegan lifestyle.
