The Polynucleotide Boom: Hype vs Reality

Polynucleotides are the most talked-about ingredient in aesthetic medicine right now. Social media is full of dramatic claims — “skin regeneration,” “biological repair,” “the end of filler.” Some of these claims have merit. Some don’t. This article separates what the science actually supports from what’s being oversold, so you can make an informed decision about whether polynucleotides are right for you.

Polynucleotides (PNs) are chains of nucleotides — the basic building blocks of DNA. In aesthetic medicine, they’re derived from salmon or trout DNA (PDRN — polydeoxyribonucleotide). When injected into the skin, they work at a cellular level to stimulate repair, improve hydration, reduce inflammation, and support new collagen and elastin production.

This isn’t a filler — it doesn’t add volume. It’s not Botox — it doesn’t relax muscles. Polynucleotides are a regenerative treatment: they aim to improve the quality of the skin itself from the inside, rather than masking what’s wrong on the surface. The most well-known brands in the UAE include Rejuran and similar PDRN-based products.

For more on the science, see what are polynucleotides.

• Improved skin hydration and moisture retention
• Increased skin thickness and elasticity over multiple sessions
• Reduced fine lines through improved skin quality (not volume)
• Anti-inflammatory effects in the treated area
• Promotion of fibroblast activity (collagen production)
• Wound healing acceleration (well-established in medical literature)
• Improvement in under-eye skin quality and mild hollowing

• “Skin regeneration” — it improves skin quality but doesn’t reverse structural aging
• “Replaces filler” — PNs don’t add volume; they can’t do what filler does
• “Permanent results” — benefits are real but temporary; maintenance sessions are needed
• “Miracle treatment” — it’s effective for skin quality but not a solution for volume loss, deep wrinkles, or sagging
• “Works for everyone” — some patients respond better than others; severely sun-damaged or very thin skin may need other treatments first

Polynucleotides work best for patients whose main concern is skin quality rather than structure or volume. The ideal candidates are:

Patients with dull, tired, dehydrated skin — especially in Dubai’s climate, where UV exposure and air conditioning take a real toll. PNs improve hydration and texture at a deeper level than topical products can reach.

Patients with fine lines from thin or aging skin — not deep wrinkles from volume loss, but the surface-level creasing that comes from reduced skin elasticity. PNs thicken the skin and improve its bounce.

Patients with mild under-eye concerns — thin skin under the eyes that’s not severe enough for filler but is creating shadows or crepiness. PNs can improve skin thickness here without the risks of volume injection.

Patients who want a natural, gradual improvement — PNs don’t create instant changes. Results build over 2–3 sessions across several weeks. Patients who prefer a slow, subtle upgrade over a visible single-session change are the best fit.

Patients looking to combine with other treatments — PNs work well alongside skin boosters, Dermapen, Profhilo, or even filler — addressing skin quality while other treatments handle structure. For comparisons, see Profhilo vs polynucleotides, skin boosters vs polynucleotides, and polynucleotides vs exosomes.

Polynucleotides are not the right treatment for every skin concern. They’re unlikely to give satisfying results if:

Your main concern is volume loss. Flat cheeks, hollow temples, thin lips — these need filler or biostimulators, not PNs. Polynucleotides improve skin quality but don’t add volume.

Your main concern is dynamic wrinkles. Forehead lines, frown lines, crow’s feet caused by muscle movement need Botox, not skin regeneration.

You want instant results. PNs work gradually over 2–3 sessions. If you want visible change tomorrow, filler or Botox delivers faster.

Your skin is severely damaged or very lax. PNs can improve texture, but they can’t tighten significantly loose skin. For more serious laxity, thread lifting or RF microneedling may be more appropriate first steps.

We offer polynucleotide treatments. We believe the evidence supports their use for skin quality improvement, hydration, and fine line reduction — particularly in Dubai’s climate, where skin takes a real beating from UV, AC, and dehydration.

We also believe the hype has outpaced the science in some areas. PNs are not a replacement for filler, Botox, or biostimulators. They’re not a miracle treatment. They’re one useful tool in a broader plan — and a doctor who tells you polynucleotides will solve everything is either uninformed or selling you something.

The best approach is an honest assessment of what your skin actually needs. Sometimes that includes polynucleotides. Sometimes it doesn’t. The only way to know is a consultation with a doctor who offers the full range of treatments and isn’t locked into pushing one product.
