It has been all over TikTok, Instagram Reels, and aesthetic clinics across the Gulf — the “salmon DNA facial,” sometimes called the “salmon sperm facial,” has become one of the most talked-about skin treatments of 2025 and 2026. But behind the viral name is a genuine medical technology with real science: polynucleotide (PN) and polydeoxyribonucleotide (PDRN) therapy.

Despite the name, this is not a facial at all — it is an injectable treatment performed by a medical professional. So what actually is it? How does it work? Is it truly salmon sperm? And does it live up to the hype? This guide cuts through the social media noise and explains what salmon DNA treatment really involves, the clinical evidence behind it, what results you can realistically expect, and how it compares to other regenerative skin treatments available in Dubai and Abu Dhabi.

Despite the viral name, you are not putting raw fish on your face. The so-called “salmon DNA facial” uses polynucleotides (PN) or polydeoxyribonucleotides (PDRN) — highly purified DNA fragments extracted from salmon or trout reproductive cells (gonads). These DNA fragments are processed through multiple filtration steps to remove all cellular material, proteins, and potential allergens, leaving a pharmaceutical-grade injectable that contains only the purified nucleotide chains.

So technically, yes — the raw material originates from salmon reproductive tissue. But by the time it reaches your skin, it is a sterile, medical-grade product that has been refined to pharmaceutical standards. The “salmon sperm facial” name is social media sensationalism for what is actually a sophisticated regenerative medicine technology.

The treatment is administered through micro-injections into the skin — not applied as a topical — making it an injectable procedure, not a facial in any traditional sense. It is a clinical treatment performed by a medical professional.

Polynucleotides work through several biological mechanisms once injected into the dermis:

Fibroblast activation — The DNA fragments activate fibroblasts, the cells responsible for producing collagen and elastin. This stimulates your skin to build new structural proteins from within — improving firmness, elasticity, and texture over time.

Adenosine A2A receptor activation — PDRN specifically activates the adenosine A2A receptor pathway, which promotes cell growth, reduces inflammation, and supports tissue repair. This is the same pathway targeted in wound healing and regenerative medicine.

Deep hydration — Polynucleotides have a strong water-binding capacity, drawing moisture into the dermal layer and improving the skin’s hydration from within. This produces the plump, dewy quality that makes the treatment so popular for “glass skin” goals.

Anti-inflammatory action — The treatment has documented anti-inflammatory properties, which can help calm reactive, sensitised, or post-procedure skin.

Barrier repair — By stimulating the production of new collagen and supporting the extracellular matrix, polynucleotides help strengthen the skin barrier — making skin more resilient against environmental stress, UV damage, and dehydration. For a deeper scientific breakdown, see what is PDRN and what are polynucleotides.

Not all polynucleotide products are identical. The most commonly used brands in Dubai and the UAE include:

The specific brand used depends on the treatment goals, the area being treated, and the clinician’s assessment. Dr Azra Vaziri selects polynucleotide products based on clinical evidence and individual patient needs.

Polynucleotide treatments are versatile and can address a range of skin concerns:

1. Consultation — Your clinician assesses your skin condition, discusses your goals, and confirms that polynucleotide treatment is appropriate. Not every skin concern needs this treatment — a good clinician will tell you if something else is more suitable.
2. Numbing — A topical anaesthetic cream is applied to the face (or target area) for 20–30 minutes to ensure comfort during injections.
3. Injection — The polynucleotide solution is injected via multiple small, shallow injections across the treatment area using a fine needle or cannula. The technique varies by brand and area — under-eye treatment requires a different approach from full-face treatment.
4. Immediately after — You may have small bumps (papules) at the injection sites. These are normal and typically resolve within 24–48 hours. Mild redness may be present.
5. Over the following weeks — The polynucleotides begin working at the cellular level. Improved hydration and glow may be noticeable within 1–2 weeks. Collagen stimulation and deeper structural benefits develop over 4–8 weeks and continue building with subsequent sessions.

A typical course involves 3–4 sessions spaced 3–4 weeks apart, with maintenance every 6–12 months.

The honest answer: mostly yes, with realistic expectations.

What it does well: Polynucleotides have a genuine, evidence-backed ability to improve skin hydration, stimulate collagen, strengthen the barrier, and produce a noticeable glow. The clinical data — particularly for Rejuran and Plinest — shows measurable improvements in skin thickness, elasticity, and hydration. PDRN has been used in regenerative medicine for over two decades, so the underlying science is not new.

What it does not do: It is not a replacement for volume restoration (that requires filler or biostimulators), it does not lift sagging skin (that requires RF microneedling or HIFU), and it is not a one-session miracle. Like most regenerative treatments, results are progressive and require a course of sessions.

The TikTok problem: Social media often compresses the timeline and overstates the drama of results. Polynucleotides produce genuine, meaningful improvement — but it is gradual, subtle, and builds over weeks. If you expect a single-session transformation because a Reel showed one, you may be disappointed. If you understand the biology and commit to a course, you will likely be very pleased.

These treatments are not competitors — they address overlapping but distinct aspects of skin health and can be combined. For example, polynucleotides for barrier repair and collagen alongside skin boosters for hydration, or combined with exosome therapy for enhanced cellular signalling after microneedling.
