Salmon DNA Facial: The TikTok Treatment Explained

What Is Salmon DNA Treatment, Really?

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. A consultation with Dr Azra Vaziri confirms whether it is the right option for your skin.

How Salmon DNA Treatment Works

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 — stimulating the 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 — 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 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 help calm reactive, sensitised, or post-procedure skin.

Barrier repair

By stimulating new collagen and supporting the extracellular matrix, polynucleotides strengthen the skin barrier — making skin more resilient against environmental stress, UV damage, and dehydration.

Polynucleotide Brands You Will Encounter

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.

What Can Salmon DNA Treatment Treat?

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

For full treatment details and booking information, see our salmon DNA treatment page. For a deeper look at how these treatments compare to other options, see our guides on dark circles treatment and glass skin treatment in Dubai.

• Dull, dehydrated skin that lacks glow — particularly common in Dubai’s climate
• Fine lines and early wrinkles
• Thin, crepey skin — especially under the eyes and on the neck
• Acne scarring and post-inflammatory marks
• Rough, uneven skin texture
• Weakened skin barrier — sensitised, reactive, or environmentally stressed skin
• Under-eye dark circles and hollowing (Rejuran I is specifically designed for this area)
• Overall skin quality improvement — the “glass skin” goal

What the Treatment Is Actually Like

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

• 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. Book your consultation.
• Numbing — A topical anaesthetic cream is applied to the face (or target area) for 20–30 minutes to ensure comfort during injections.
• 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.
• 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.
• 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.

Does Salmon DNA Treatment Live Up to the Hype?

What it does well

Polynucleotides have a genuine, evidence-backed ability to improve hydration, stimulate collagen, strengthen the barrier, and produce a noticeable glow. 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.

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. Results are progressive and require a course of sessions.

The TikTok problem

Social media compresses the timeline and overstates the drama of results. Polynucleotides produce genuine, meaningful improvement — but it is gradual, subtle, and builds over weeks. Understand the biology and commit to a course, and you will likely be very pleased.
