Most people come to aesthetics looking for one of two things: to soften something or to add something back. Polynucleotides sit in a different category entirely. They are not about filling or freezing. They are about repair — helping skin function better at a cellular level so it looks and behaves more like healthy skin.
If you have been told your skin looks tired, dull, or just “off,” but injectables do not feel like the right answer yet, polynucleotides may be worth exploring.
Here is what they are, how they work, who tends to benefit, and what to realistically expect.
What Polynucleotides Actually Are
Polynucleotides are highly purified chains of DNA, typically derived from salmon or trout. The DNA is processed to remove proteins that could cause a reaction, leaving only the biocompatible nucleotide strands.
These molecules are not foreign to the body. Your own cells use similar building blocks every day. When introduced into the skin, polynucleotides are recognized and used — not rejected — which is part of what makes them well-tolerated and suitable for a wide range of patients.
How They Support Skin Repair
Polynucleotides work through several mechanisms at once:
- Fibroblast activation: They stimulate the cells responsible for producing collagen and elastin, supporting the skin’s structural framework over time.
- Deep hydration: They attract and bind water molecules within the tissue, improving moisture retention at a deeper level than topical products can reach.
- Antioxidant activity: They help neutralize free radicals, reducing oxidative stress that accelerates skin aging.
- Anti-inflammatory effects: They calm chronic low-grade inflammation in the skin, which is often an underlying factor in dullness and uneven texture.
The result is not an instant transformation. It is a gradual improvement in skin quality — firmer, more hydrated, more even, and more resilient.
Who May Benefit
Polynucleotides are particularly well-suited to patients who want regeneration rather than dramatic change. They are commonly used for:
- Skin that appears tired, thin, or lacking glow
- Fine lines caused by dehydration or poor skin quality rather than movement
- Delicate areas like the under-eyes, where traditional fillers carry higher risk
- Post-acne skin recovering from inflammation or scarring
- Skin that is sun-damaged or prematurely aged
- Patients who want to maintain results from other treatments by improving baseline skin health
They work well as a standalone treatment and also complement other procedures. Many practitioners include them as part of a broader skin health plan.
What to Expect From Treatment
Polynucleotides are administered through small injections into targeted areas. The treatment itself is generally quick, and most patients return to normal activity the same day.
Results build gradually. Most patients notice an improvement in skin texture and hydration within a few weeks, with more visible changes in firmness and tone developing over two to three months. A course of treatments is typically recommended, followed by maintenance sessions.
The key takeaway: polynucleotides reward patience. The changes are real, but they reflect genuine biological repair rather than a surface-level quick fix.
Is It Right for You?
If your concern is skin quality — not just specific lines or volume loss — polynucleotides offer a targeted, evidence-supported way to address that. Book a consultation with Ness Aesthetics, and we will help you understand whether they are appropriate for your skin type, concerns, and goals, and how they might fit into a wider treatment plan.
