Why Is PDRN in So Many Skincare Products Now? Dermatologists Explain the Benefits
Some ingredients arrive with a whisper and others arrive with a whole conversation already running. PDRN belongs firmly in the second group. Short for polydeoxyribonucleotide, it is being talked about as one of the year’s buzziest skincare ingredients, credited with helping skin cells regenerate, supporting the skin barrier, and aiding wound healing — and it is now turning up in facials, serums, sheet masks, and more.
The question behind all that noise is a simple one: does PDRN actually live up to the hype, and does it deserve a place in your routine? This guide is a deep dive into exactly that, built around the views of three dermatologists, so you can judge the ingredient on its evidence and its limits rather than on its reputation alone.
The experts consulted are Dr. Roberta Del Campo, MD, a board-certified dermatologist and chief medical officer of Skin Laundry; Dr. Marnie Nussbaum, MD, FAAD, a board-certified dermatologist and founder of Marnie Nussbaum Dermatology & Aesthetics in New York City; and Dr. Faranak Kamangar, MD, a board-certified dermatologist and a member of Rodan + Fields’ Dermatologist Advisory Board.
What Is PDRN?
Dr. Del Campo describes PDRN in plain terms: it is essentially purified DNA fragments taken from salmon sperm. Because those fragments are biocompatible with human DNA, she explains, skin cells recognise them and respond to them as repair signals rather than treating them as foreign material.
The mechanism she outlines starts with adenosine A2A receptors. Activating those receptors, she says, sets off a regenerative chain: fibroblasts are stimulated to produce more collagen and elastin; microcirculation improves, bringing more nutrients and oxygen to the skin; tissue repair and wound healing speed up, which is why PDRN is presented as a good fit after laser or other procedures; inflammation and oxidative stress are reduced; and moisture retention improves as the barrier is strengthened.
Benefits of PDRN for Skin
It is worth noting how widely PDRN has already been tried — celebrities have had it, and Byrdie’s own Derek Deng has tried it too — but trying something is not the same as proving it works. So what are the actual benefits, according to the dermatologists?
Dr. Del Campo places PDRN in a wider shift in aesthetics: away from quick surface fixes and toward regenerative medicine, cellular repair, and longevity-focused treatments. PDRN, she says, sits at the meeting point of all three, because it works at a cellular level on the root causes of ageing and damage rather than only on what shows on the surface.
Within that picture, she lists several benefits. Faster wound healing and tissue repair come through the formation of new blood vessels and better microcirculation, which makes PDRN useful for recovery after procedures and for acne scars. Its anti-inflammatory and antioxidant effects reduce oxidative stress, calm irritation, and help protect against premature ageing by neutralising free radicals that can damage DNA. A stronger skin barrier means better moisture retention and hydration. And healthy cell turnover helps smooth fine lines, even out skin tone, and fade hyperpigmentation.
That is not the whole story, though, and the article is clear that not every dermatologist is on board yet. Dr. Nussbaum does not currently offer PDRN treatments at her practice. She stresses that the ingredient lacks regulation and is not FDA approved, and that how well it works may depend on the concentration used and the quality of the formulation. Her practical advice, reflected in the article, is to try PDRN first in a simpler formulation such as a moisturiser before paying for an expensive facial.
Potential Side Effects and Skin Type Considerations
Side effects and suitability are where the dermatologists’ advice gets most specific, and it starts with allergies. Dr. Nussbaum says people with fish allergies, and people with seafood sensitivities, should patch test first or avoid PDRN altogether.
At the same time, Dr. Del Campo says PDRN is generally well tolerated across all skin types. The two points sit together: the ingredient itself is described as broadly tolerated, but an individual allergy changes the calculation entirely.
Side effects can also vary with the formula and the person. Irritation may come not from PDRN itself but from other ingredients in the product, such as fragrance, niacinamide, or other actives layered alongside it, and that irritation can show up as redness or breakouts. Injectable forms given in a salon or clinic carry a higher risk of swelling, bruising, or allergic reactions, and they are not FDA-cleared in the United States. People with sensitive or reactive skin should start slowly and watch how their skin responds.
Plant-Derived PDRN
Salmon sperm facials and salmon-derived skincare started this conversation, but they are not the only way in. Brands are increasingly developing plant-based, biotech-derived alternatives that aim for similar rejuvenating effects without any animal-derived ingredients.
The example given is Clinique’s newest launch, the Smart Clinical Repair Collagen + PDRN Cream. It uses a biotech-derived PDRN alternative sourced from the cica plant, is formulated for topical use, and is designed to target visible signs of ageing by supporting the skin’s foundation, so that skin appears stronger, firmer, and more resilient over time.
How to Incorporate PDRN Into Your Routine
Injection Facials. Dr. Kamangar says PDRN is used mainly through microinjections into the skin, for rejuvenation and repair, with the option of topical application after procedures to help healing along. She adds an important qualification: although the ingredient rests on historical wound-healing research, its cosmetic popularity has run well ahead of the current depth of mechanistic evidence, and more dermatologic trials are still needed to fully understand its true anti-ageing and skin-restorative potential.
Topical Skincare. For topical use, Dr. Del Campo says PDRN should be applied to clean, dry skin for the best penetration, without interference from oils, serums, or other products layered underneath or over it.
Dylan Marino’s own experience, described in the source article, was a needle-free route rather than injections. She went for a PDRN boost at her local Jersey City Heyday, applied during a facial as tiny serum drops using nano-encapsulation, followed by a “Collagen Intensive Phyto-Retinol Renewal Mask” and a microcurrent treatment. She describes the feeling as odd but not uncomfortable — a sensation of flashing lights as she lay with her eyes closed, and a taste of pennies in her mouth — while calling the experience itself fast, painless, and easy, and saying she personally felt glowier than ever when she left.
Post-Treatment Recovery. Dr. Del Campo also describes Skin Laundry’s PDRN treatment, called “Cell Regenerator”: a post-facial enhancement treatment combining one billion exosomes per ml with clinical-grade PDRN, synthetic exosomes, and vegetable stem cells. Applied immediately after laser or resurfacing treatments for deep dermal penetration, it is said to accelerate healing, reduce fine lines, improve firmness, and calm inflammation. In her account, professional-grade encapsulation technology ensures the actives reach skin cells intact — something retail products cannot replicate.
The closing verdict is deliberately measured: to each their own. Facials and topical products can be a way to explore the ingredient, but the dermatologists recommend bringing PDRN into a routine thoughtfully and with caution — and more research is still needed to confirm the long-term benefits of the salmon-derived ingredient.
