Is Vegan PDRN Skincare Actually Better Than Salmon PDRN? What the Science Really Says

Vegan PDRN vs. Salmon PDRN: What Dermatologists Say About the Biggest Differences

Salmon-derived PDRN moved from Korean dermatology clinics into serums and masks worldwide, and plant-based versions are now landing on beauty shelves under the same acronym. The pitch is familiar — regenerative skin repair, cruelty-free — but the science tells a more complicated story. Expect the next wave of “vegan PDRN” launches to force a sharper conversation about what the label actually means.

What Is Vegan PDRN?

Brands are using biotechnology to produce plant-derived ingredients marketed as vegan alternatives to PDRN, drawing from sources including ginseng, seaweed, rice and rose. Haruharu Wonder’s Rose PDRN, for instance, is created from callus cells of the Damask rose through biotechnology and purification processes. The brand’s internal testing suggests the ingredient may support skin renewal and improve the appearance of wrinkles, citing increased wound-healing markers and proteins tied to skin elasticity.

Traditional PDRN — polydeoxyribonucleotide — is purified DNA extracted primarily from salmon sperm, and sometimes trout. “PDRN stands for polydeoxyribonucleotide—it is essentially purified DNA fragments extracted from salmon sperm. These polynucleotides are biocompatible with human DNA, meaning our skin cells recognize and respond to them as if they were our own repair signals,” Roberta Del Campo, MD, board-certified dermatologist and chief medical officer at Skin Laundry, told Byrdie.

Many vegan versions are not molecularly identical. They aim to mimic PDRN’s regenerative pathways rather than replicate them.

Why More People Are Choosing Vegan PDRN Skincare Instead

Three forces are pushing the category forward. Consumer demand for vegan, cruelty-free and religiously compliant formulations has expanded across skincare, and PDRN — sourced from fish reproductive material — is an obvious target for reformulation. Biotech is now cheap and capable enough to grow plant callus cells and isolate active compounds at commercial scale. And the original ingredient’s clinical reputation, built over decades of injectable use, gives brands a familiar name to lean on.

Experts warn that shorthand is doing heavy lifting. “It has to be purified DNA—not just extracts that contain DNA—to qualify as PDRN,” Danny Guo, MD, a double board-certified dermatologist in Calgary, told Marie Claire. Victoria Fu, cosmetic chemist and co-founder of Chemist Confessions, made a similar point to Marie Claire: true PDRN refers to the fragmented DNA itself, not an ingredient designed to recreate some of its effects. A plant extract that mimics certain functions without containing identifiable DNA fragments is more accurately called PDRN-inspired.

“I would say it’s promising, but vegan PDRN cannot simply borrow the reputation of traditional PDRN, which has been studied so well for so many years now.”

What Could Be Next for PDRN Skincare

The vegan PDRN category will keep growing — and regulators, chemists and dermatologists will start pushing back on the naming. Traditional PDRN has been studied since the 1990s, primarily for wound healing and tissue repair via injection or application to injured skin. Vegan alternatives currently rest on preclinical and early data, with no robust peer-reviewed studies yet. That gap will shape the next 12 to 18 months in three ways.

Reformulation and relabeling comes first. As chemists like Fu draw a harder line between PDRN and PDRN-inspired ingredients, brands leaning on the acronym without purified DNA fragments will face pressure to clarify their claims.

Reader action: Before you buy, check the ingredient list for the actual active. A rose callus extract or a ginseng-derived polynucleotide is not the same molecule as salmon-derived PDRN, and the label should say so.

Next, dermatologists will separate how they position each version. Traditional PDRN’s regenerative case is built on clinical injectables. Anetta Reszko, MD, FAAD, a board-certified dermatologist in New York City, told Women’s Health that its “regenerative properties support cellular renewal and stimulate fibroblasts to increase collagen production, helping skin recover more efficiently after stress or injury.” Vegan topicals are unlikely to clear that bar in the near term.

Reader action: Match the product to the goal. For hydration and barrier support, a vegan PDRN cream paired with ceramides, panthenol or niacinamide can deliver. For the regenerative response associated with clinical PDRN, a topical — vegan or otherwise — is probably not the right tool.

Finally, expect clearer expectation-setting from clinicians. Dr Yash Mehta, facial plastic surgeon and founder of Aesthetic and Cosmetic Surgery (ACSC), told Vogue India that patients should understand “‘inspired by’ and ‘equivalent to’ are very different things.” He added: “I would first ask: what are you expecting from it? If your goal is hydration and barrier support, there may still be value. If you expect to recreate the regenerative response we sometimes seek clinically with injectable treatments, I would probably reset those expectations early.”

Reader action: If you are switching for ethical, religious, dietary or allergy reasons, that is a valid trade-off — just do not treat it as a like-for-like swap.

The bottom line: vegan PDRN is a real category with real formulation value, but the acronym is doing work the science has not yet earned. Buy the product, not the name.

THREE SIGNALS TO WATCH
1. Peer-reviewed clinical studies on plant-derived PDRN alternatives moving beyond preclinical data
2. Regulatory or industry guidance requiring brands to distinguish “PDRN” from “PDRN-inspired” on labels
3. Launches from major K-beauty or clinical skincare brands using vegan PDRN as a headline active
