Skincare’s latest obsession is salmon sperm. More accurately known as PDRN (polydeoxyribonucleotide), the ingredient has gone from in-office treatments to the shelves of beauty retailers, bottled into cleansers, toners, serums, and creams. And it’s easy to see the appeal. PDRN has been associated with skin regeneration, tissue repair, and improved barrier function, making it sound like the ultimate shortcut to healthier-looking skin.
But there’s an important distinction between getting PDRN through a procedure and slathering it onto your face.

Procedure vs. Product
The answer is a little more complicated than a simple yes or no.
PDRN used in procedures is delivered directly into the skin, while topical products have to contend with the skin barrier. Standard PDRN molecules are generally too large to penetrate intact skin effectively, which is why procedures such as injections and microneedling are often used to deliver the ingredient deeper into the skin.
Newer formulations are exploring smaller PDRN molecules and different delivery systems to improve absorption. However, smaller doesn’t necessarily mean equivalent to an injectable treatment. The formulation, molecular size, delivery system, and clinical evidence all matter.
K-beauty brands like Anua and Medicube have brought PDRN into the everyday skincare routine, but don’t let the PPM (parts per million) figure be your only guide. A higher concentration doesn’t automatically mean better absorption or better results.
Vegan PDRN
For those who prefer to avoid animal-derived ingredients, vegan or “phyto-PDRN” uses plant-derived materials such as ginseng and rose as alternatives to animal-derived DNA.
The catch? Vegan PDRN is still relatively new, and there isn’t enough long-term human research to say that it works exactly like conventional PDRN. So while it may be promising, “vegan” doesn’t automatically mean clinically equivalent.
Ultimately, PDRN may have impressive credentials in the treatment room, but a serum shouldn’t be expected to perform like an injectable. It can be an interesting addition to your routine, but it isn’t the only ingredient with skin-repairing benefits. When in doubt, tried-and-tested ingredients like retinoids—and gentler alternatives like bakuchiol—still have a stronger evidence base.

Frequently Asked Questions
Not exactly. PDRN injections and microneedling deliver the ingredient directly into the skin, while standard PDRN molecules are generally too large to penetrate intact skin effectively through topical products like serums and creams.
PDRN (polydeoxyribonucleotide) is an ingredient associated with skin regeneration, tissue repair, and improved barrier function. Originally used in in-office procedures, it’s now formulated into topical cleansers, toners, serums, and creams by K-beauty brands like Anua and Medicube.
Not necessarily. A higher PPM (parts per million) concentration doesn’t automatically mean better absorption or results. Formulation, molecular size, delivery system, and clinical evidence all matter more than concentration alone.
Vegan PDRN, or phyto-PDRN, uses plant-derived materials like ginseng and rose instead of animal-derived DNA. It’s a newer formulation without enough long-term human research to confirm it works exactly like conventional, animal-derived PDRN.
Tried-and-tested ingredients like retinoids, and gentler alternatives like bakuchiol, still have a stronger evidence base than topical PDRN for skin-repairing benefits, making them worth considering alongside or instead of PDRN products.
