The short answer
- Polynucleotides (often sold as “salmon DNA”, brands like Plinest and Rejuran) are purified DNA fragments injected into the skin to stimulate your own fibroblasts, hydration and collagen. The evidence for skin quality is growing and generally positive.
- Exosomes are cell-derived vesicles carrying growth signals, usually applied topically after microneedling or laser. The evidence is early and the regulatory picture is uncertain.
- These are two different treatments that often get bundled together in marketing. They are not the same thing and should not be sold as if they were.
- Typical Dubai pricing is roughly AED 900–1,800 per polynucleotide session and AED 1,200–3,000 per exosome session, confirmed case by case with the clinic.
- For newer treatments, a licensed doctor and a traceable, properly sourced product matter more than ever. Always check the clinic and injector's DHA licence first.
If you have spent any time reading Dubai clinic menus lately, you have seen the words “regenerative” and “salmon DNA” and “exosome glow” used almost interchangeably. They are not interchangeable. They are two separate treatments with very different levels of evidence behind them, and the marketing tends to blur that line because both sound futuristic and both promise the same thing: better skin from the inside out.
This guide separates them cleanly. It explains what each one is, how it is delivered, what the science currently supports, and the specific caveats you should carry into a consultation. The tone here is deliberately measured. These are emerging treatments, and the honest position is that one of them is well on its way to being an established skin-quality tool, while the other still carries real questions you deserve to have answered before you pay for it.
Two treatments, not one
The quickest way to keep them straight: polynucleotides are injected and work by stimulating your own skin cells, while exosomes are usually applied to the surface after a treatment that opens tiny channels in the skin, and work by delivering signalling molecules. Different substances, different delivery, different evidence base.
Both belong to a broader shift in aesthetics away from simply adding volume and towards biostimulation, the idea of prompting the skin to repair and rebuild itself. That is the same category that products like Profhilo and other skin boosters live in, which is why these newer options are best understood next to treatments you may already know.
What polynucleotides actually are
Polynucleotides are short and long chains of purified DNA fragments, most commonly extracted from the sperm cells of salmon or trout and then highly purified. This is where the “salmon DNA” nickname comes from. The best-known brand names on the Dubai market are Plinest and Rejuran, and you will also see the closely related ingredient PDRN (polydeoxyribonucleotide) described in the same breath.
Injected into the skin in a series of tiny points, polynucleotides are thought to work by stimulating fibroblasts, the cells responsible for producing collagen and elastin, while also improving hydration and supporting the skin's own repair processes. The result people are chasing is not volume or a “filled” look. It is skin quality: firmer, more hydrated, smoother texture, softened fine lines, and a general improvement in tone. Polynucleotides are used across the face and are particularly popular for under-eye rejuvenation, where the skin is thin and delicate and heavier fillers carry more risk.
On the evidence, this is the more reassuring of the two treatments. A body of clinical work, including pooled reviews of controlled studies, reports genuine improvements in skin texture, elasticity and fine lines over a treatment course, with side effects that are usually mild and temporary such as swelling, redness or minor bruising at the injection points. It is still a maturing field, and the largest, longest studies are yet to come, so the fair framing is “promising and increasingly well-supported for skin quality” rather than “proven beyond doubt.” As with any injectable course, results build gradually, and a typical protocol is 2 to 3 or more sessions spaced a few weeks apart, followed by maintenance.
What exosomes actually are
Exosomes are microscopic vesicles released by cells. In the body they act as messengers, carrying proteins, growth factors and genetic signals between cells to coordinate processes like healing. In aesthetics, exosome products are usually derived from cultured cells (often stem cells) and are applied topically to the skin immediately after a treatment that creates temporary micro-channels, most often microneedling or a laser. The theory is that these channels let the exosomes penetrate, where their growth signals are meant to boost healing, glow and collagen production.
Here the honesty has to be turned up. Exosomes for skin are an emerging area with limited robust clinical evidence in humans, and, just as importantly, significant regulatory uncertainty. The US Food and Drug Administration has been explicit that there are currently no FDA-approved exosome products, and it has issued public warnings about unapproved products being marketed with bold claims, in some cases linked to serious harm. Their regulatory status for cosmetic use varies from country to country and is still being worked out. None of this means exosomes are worthless, and early results reported by clinics for post-procedure recovery and glow are interesting. It does mean the claims deserve scrutiny and the product deserves questions.
Because exosome products are not standardised or approved the way a licensed injectable is, the specific product matters enormously. Ask the clinic exactly what they are using, what cells it is derived from, where it is sourced and manufactured, and what its regulatory status is in the UAE. A confident, compliant clinic will answer plainly. Treat any “miracle” or “cure” language, or reluctance to name the product, as a reason to slow down.
How they compare to treatments you already know
The easiest way to place these two is next to the biostimulation and skin-quality treatments Dubai patients are already familiar with: Profhilo and other skin boosters, and PRP (the “vampire facial” that uses your own blood). This table anchors the new against the known.
| Treatment | What it is | How it is delivered | Evidence maturity | Best use | Sessions |
|---|---|---|---|---|---|
| Polynucleotides | Purified DNA fragments (salmon or trout) | Injected into the skin | Growing, generally positive | Skin quality, under-eye, fine lines | 2–3+ then maintenance |
| Exosomes | Cell-derived signalling vesicles | Topical, after microneedling or laser | Early, plus regulatory uncertainty | Post-procedure glow and recovery | Often a short course |
| Profhilo / skin boosters | Stabilised hyaluronic acid | Injected into the skin | Established for skin quality | Hydration, firmness, glow | 2–3 then maintenance |
| PRP | Your own concentrated platelets | Injected or applied after microneedling | Reasonable, especially for hair | Skin quality and early hair thinning | 3–4 then maintenance |
The pattern worth noticing: polynucleotides and Profhilo are both injected, both target skin quality over a course, and both now sit on reasonably solid ground, while exosomes are the outlier on delivery (topical) and on evidence (early). PRP has been around the longest and remains a sensible, well-understood option. If you want the full side-by-side of the hyaluronic-acid options, our guide on Profhilo vs skin boosters in Dubai covers that decision in detail.
Who they suit and what to realistically expect
Polynucleotides suit people whose main concern is skin quality rather than volume or lift: dull, tired, crepey or dehydrated skin, early fine lines, and delicate zones like the under-eye where a lighter, regenerative approach is preferred over heavier filler. If you want your face reshaped or a hollow filled, this is the wrong tool, and a filler or a different treatment is the honest answer.
Exosomes, in current practice, make most sense as an add-on to a procedure you are already having, such as microneedling or a resurfacing laser, where the goal is a smoother recovery and an extra push on glow. They are not a standalone structural treatment, and they should not be sold as one.
Expectations should be calibrated. Regenerative treatments work gradually because you are waiting on your own skin to respond, so the change is a steady improvement over weeks, not an overnight transformation. Combining these treatments is common and can be sensible, for example pairing microneedling with a regenerative product, or running a course of polynucleotides alongside good skincare and sun protection, which matters year-round in Dubai. Downtime is usually modest: small bumps, redness or minor bruising at injection points for polynucleotides, and the redness and flaking of the underlying microneedling or laser for exosome protocols, typically settling within a few days.
One principle applies more forcefully to newer treatments than to established ones. When a product is emerging and, in the case of exosomes, not formally approved, the skill and licensing of the person treating you and the traceability of what they are using become the whole ballgame. A licensed doctor working in a DHA-licensed facility, using a product they can name and source, is not a nice-to-have here. It is the baseline.
What polynucleotides and exosomes cost in Dubai in 2026
Both are usually sold per session, and both are course treatments, so the per-session figure is only part of the real cost. For context, a single Profhilo session in Dubai runs roughly AED 1,800–3,000, and a facial mesotherapy session starts around AED 500, which helps place the ranges below. Treat these as typical guides and confirm the exact figure, and the exact product, with the clinic.
| Treatment | Priced by | Typical Dubai price (2026) |
|---|---|---|
| Polynucleotides, single session | Per session | AED 900 – 1,800 |
| Polynucleotide starting course | 2–3 sessions | AED 2,500 – 5,000 |
| Under-eye polynucleotides | Per session | AED 1,000 – 2,000 |
| Exosomes (add-on to microneedling or laser) | Per session | AED 1,200 – 3,000 |
A note on suspiciously cheap or suspiciously expensive offers. A very low price on a “regenerative” session can mean an unverifiable product, and a very high one does not guarantee a better or better-sourced one. What protects you is knowing the brand, the source and the protocol, not the size of the number. For a broader view of what everything costs, see our UAE aesthetic price guide.
What to ask before you book
Because these are newer treatments, a short list of direct questions filters out most of the risk:
- What exactly are you injecting or applying? You should get a specific product and brand name, not just “salmon DNA” or “exosomes.”
- Where is it sourced and what is its regulatory status here? Especially important for exosomes, given there is no FDA-approved exosome product and status varies by country.
- Who is treating me, and are they a licensed doctor? Take two minutes to verify the clinic and injector on the DHA registry.
- How many sessions, and what happens if it does not work for me? A course-based, maintenance-based answer is honest; a one-off “permanent” promise is not.
- Is a brand actually approved for aesthetic use in the UAE? Our guide to approved injectable brands in the UAE explains why this matters.
If you would rather not work through all of this alone, that is what we are here for. Tell us your skin concern and your area of the UAE, and we will match you with licensed clinics that can name their products and quote you fairly.
