Is Vegan PDRN Superior? Insights from Scientific Research

Derivatives of PDRN from salmon have transitioned from Korean dermatology clinics to global serums and masks, with plant-based alternatives now appearing on beauty store shelves under the same acronym. The message is well-known — promoting regenerative skin repair and cruelty-free practices — yet the scientific narrative is more intricate. The upcoming wave of “vegan PDRN” launches is set to ignite a more profound discussion regarding the true meaning of this label.

What Is Vegan PDRN?

Utilizing biotechnology, brands are crafting plant-derived ingredients that are marketed as vegan substitutes for PDRN, drawing from sources such as ginseng, seaweed, rice, and rose. For example, Haruharu Wonder’s Rose PDRN is developed from the callus cells of the Damask rose through biotechnological and purification methods. The brand’s internal studies suggest this ingredient may enhance skin renewal and diminish the appearance of wrinkles, referencing improved wound-healing markers and proteins associated with skin elasticity.

Traditional PDRN — or polydeoxyribonucleotide — is purified DNA primarily derived from salmon sperm, and occasionally from trout. “PDRN stands for polydeoxyribonucleotide — essentially it is purified DNA fragments derived from salmon sperm. These polynucleotides align well with human DNA, allowing our skin cells to recognize and respond to them as if they were our own repair signals,” Roberta Del Campo, MD, a board-certified dermatologist and chief medical officer at Skin Laundry, shared with Byrdie.

Many vegan alternatives are not molecularly identical. Instead, they aim to replicate PDRN’s regenerative pathways rather than duplicating them.

Why More People Are Choosing Vegan PDRN Skincare Instead

Three key factors are driving this category’s advancement. The consumer demand for vegan, cruelty-free, and religiously compliant formulations has permeated the skincare sphere, making PDRN — derived from fish reproductive material — an evident target for reformulation. The biotech landscape has evolved to be affordable and efficient enough to cultivate plant callus cells and extract active compounds on a commercial scale. Furthermore, the longstanding clinical credibility of the original ingredient, which has been utilized in injectables for decades, provides brands with a familiar reference point.

Experts caution that the shorthand is bearing significant weight. “It needs to be purified DNA — not merely extracts containing DNA — to qualify as PDRN,” Danny Guo, MD, a double board-certified dermatologist in Calgary, noted to Marie Claire. Victoria Fu, a cosmetic chemist and co-founder of Chemist Confessions, echoed this with a similar remark to Marie Claire: true PDRN relates to fragmented DNA itself, rather than an ingredient created to imitate some of its effects. A plant extract that emulates specific functions without containing recognizable DNA fragments is more accurately termed PDRN-inspired.

“I would describe it as promising, but vegan PDRN cannot simply adopt the reputation of traditional PDRN, which has been extensively studied over many years.”
— Dr. Swetha Dilip, aesthetic physician at The White Door

What Could Be Next for PDRN Skincare

The vegan PDRN sector is expected to keep expanding — and regulators, chemists, and dermatologists will begin to scrutinize the naming conventions more closely. Traditional PDRN has been explored since the 1990s, primarily for its role in wound healing and tissue repair via injections or topical applications on injured skin. Vegan alternatives currently rely on preclinical and preliminary data, with no comprehensive peer-reviewed studies available yet. This disparity will shape the forthcoming 12 to 18 months in three principal ways.

First, reformulation and relabeling will take precedence. As chemists like Fu delineate a stricter boundary between PDRN and PDRN-inspired ingredients, brands using the acronym without purified DNA fragments will encounter mounting pressure to clarify their claims.

Reader action: Before purchasing, review the ingredient list for the actual active component. A rose callus extract or a ginseng-derived polynucleotide does not equate to the same molecule as salmon-derived PDRN, and the label should reflect that.

Secondly, dermatologists will differentiate how they classify each version. Traditional PDRN’s regenerative argument is grounded in clinical injectables. Anetta Reszko, MD, FAAD, a board-certified dermatologist in New York City, mentioned to Women’s Health that its “regenerative properties foster cellular renewal and stimulate fibroblasts to boost collagen production, assisting the skin in recovering more effectively after stress or injury.” Vegan topicals will likely struggle to meet that standard in the immediate future.

Reader action: Align the product with your objectives. For hydration and barrier support, a vegan PDRN cream combined with ceramides, panthenol, or niacinamide may suffice. However, for the regenerative response associated with clinical PDRN, a topical — whether vegan or not — may not be the right approach.

Lastly, anticipate clearer expectations from clinicians. Dr. Yash Mehta, facial plastic surgeon and founder of Aesthetic and Cosmetic Surgery (ACSC), told Vogue India that patients should recognize “‘inspired by’ and ‘equivalent to’ represent two very different concepts.” He suggested: “I would first inquire: what are you hoping to achieve with it? If your aim is hydration and barrier protection, there may still be merit. However, if you are expecting to replicate the regenerative response that is sometimes sought clinically through injectable treatments, I would recommend adjusting those expectations early.”

Reader action: If your switch is motivated by ethical, religious, dietary, or allergy-related reasons, that is a valid trade-off — just do not perceive it as a direct substitution.

The conclusion: vegan PDRN is a legitimate category with valuable formulation potential, although the acronym is carrying more weight than the current science supports. Purchase the product based on its merits, not just the name.

THREE SIGNALS TO WATCH
1. Peer-reviewed clinical studies on plant-derived PDRN alternatives advancing beyond preclinical data
2. Regulatory or industry guidelines necessitating brands to distinguish “PDRN” from “PDRN-inspired” on labels
3. Launches from major K-beauty or clinical skincare brands promoting vegan PDRN as a primary active ingredient
