Short answer: the viral "salmon sperm" trend refers to PDRN — polydeoxyribonucleotide sourced from salmon DNA. In clinics it's delivered as an injectable (a procedure performed by trained practitioners); at home, you get the same hero ingredient topically in serums and with gentle microneedling. Here's the full picture, minus the hype. Prefer to skip the needles? Browse topical PDRN skincare.
New skincare trends pop up constantly, and few have raised eyebrows like the so-called "salmon sperm facial." In this guide we explain what people actually mean by salmon sperm injections and salmon DNA skincare, the key terms — PDRN, polynucleotides, Rejuran — and how to enjoy the trend in a cosmetic, at-home way.
What does "salmon sperm" skincare actually mean?
The headline-grabbing name refers to PDRN (polydeoxyribonucleotide) and PN (polynucleotide) — fragments of DNA purified from salmon. The "sperm" tag comes from the part of the fish the DNA is extracted from, but in finished products it's simply a purified cosmetic ingredient. You'll see it marketed as salmon DNA skincare or PDRN skincare. It isn't new — it has been used in Korean skincare for over a decade and is only recently popular in Australia.
Why salmon?
Salmon DNA is structurally very similar to human DNA, which makes it a biocompatible, gentle ingredient that's well suited to skincare. It's abundant and typically sourced as a by-product of the food industry.
PDRN vs PN: what's the difference?
Both are DNA-derived and valued in skincare for their gentle, hydrating, skin-conditioning feel. PDRN is the more established, longer-studied form often associated with the look of overall rejuvenation, while PN refers to shorter DNA fragments often highlighted for surface hydration. In cosmetics, both support the appearance of smooth, hydrated, even-looking skin — they are not medicines and don't treat medical conditions.
Injectable vs topical: the important distinction
This is where most of the confusion lives, so let's be clear.
- Injectable treatments (e.g. Rejuran, "skin booster" mesotherapy). These deliver PDRN/PN below the skin and are clinical procedures performed only by trained, qualified practitioners. They are regulated as therapeutic goods. We don't sell injectables, and nothing here is intended to be injected.
- Topical salmon DNA skincare. Serums, ampoules, masks and capsules you apply to the surface of your skin at home — optionally paired with gentle microneedling. This is the cosmetic category we work in.
What is a "salmon sperm facial"?
When people talk about a salmon sperm facial in a cosmetic, at-home sense, they usually mean applying a topical PDRN serum and using gentle microneedling to help it absorb. It's a lovely way to enjoy the trend without a clinic visit — supporting the look of hydrated, fresh, even-toned skin.
What people love about salmon DNA skincare (cosmetically)
- Hydration: PDRN is water-loving, so it helps skin look and feel plump and hydrated.
- Calm, even look: it's a gentle, non-stinging ingredient that suits skin that reacts to stronger actives.
- Smoother appearance: with consistent use, many people notice the look of smoother texture and more even tone.
- Layers well: it sits happily under moisturisers and SPF.
A realistic note: this is a gentle, cumulative cosmetic ingredient, not an overnight miracle and not a medical treatment. If you have a specific skin condition, that's a conversation for your GP or dermatologist.
How to enjoy the trend at home
You don't need needles to enjoy salmon DNA. A topical PDRN serum goes on cleansed skin before your moisturiser, once or twice a day. If you like, you can pair it with gentle at-home microneedling (0.25–0.5mm) to help it absorb. For a guided start, a salmon DNA bundle pairs the serum and device together.

Is it safe?
Topical salmon DNA products are cosmetics. As with any new skincare, patch test first, and note they're not suitable for those with fish allergies. For any clinical or injectable treatment, always see a qualified practitioner and discuss your suitability and any risks with them directly.
