How Long Do Polynucleotide Injections Last?

Polynucleotides are one of the latest advances in regenerative aesthetics, designed to repair and rejuvenate the skin from within. They work differently from dermal fillers or traditional injectables by stimulating tissue repair, improving hydration, and boosting collagen and elastin production. But how long do polynucleotide injections last, and what should you realistically expect?

How Polynucleotides Work

Polynucleotides are chains of DNA fragments, usually derived from purified sources such as salmon, that act as skin “scaffolding”. Once injected, they encourage fibroblasts — the skin’s repair cells — to regenerate and restore healthy function. This makes them ideal for treating fine lines, dullness, laxity, and even sensitive conditions like rosacea.

How Long Do Results Last?

Results typically last around 6 to 12 months, depending on the area treated, the product used, and individual skin health. Improvements often continue to build for several weeks after treatment as collagen and elastin are gradually stimulated. A course of treatments is usually recommended for the best long-term outcome.

How Many Sessions Do You Need?

Most people start with a course of 2 to 3 sessions, spaced a few weeks apart. This creates a strong foundation of skin regeneration. After the initial course, maintenance sessions every 6–12 months help sustain results and keep the skin in optimal condition.

Factors That Influence Longevity

Several factors can affect how long your results last, including:

• Your age and skin quality
• Lifestyle habits such as smoking or sun exposure
• The specific polynucleotide brand used
• How well you follow aftercare advice

Taking care of your skin with good daily SPF and medical-grade skincare will help extend the benefits.

Are Results Permanent?

Polynucleotides don’t offer permanent results, because the natural ageing process continues. However, they create long-term improvements in skin health and structure, making the skin stronger and more resilient over time.

So, How Long Do Polynucleotide Injections Last?

If you’ve been wondering how long do polynucleotide injections last?, the answer is usually 6 to 12 months, with results building gradually after a course of treatments. Regular maintenance can extend their benefits, helping your skin stay healthier, firmer, and more radiant for the long term.
