The "salmon sperm skincare" thing is funny until you're vegetarian and realizing it might actually be off-limits. Good news: plant-derived PDRN is a real, researched option — not just a marketing pivot. Here is what it actually is and whether it holds up.
The Short Answer
Traditional PDRN is not vegan. It is derived from the sperm cells (milt) of chum salmon or rainbow trout — a process that involves harvesting from fish. For anyone avoiding animal-derived ingredients, conventional PDRN products are off the table.
However, plant-derived PDRN — sometimes called Phyto-PDRN or L-PDRN — is a genuinely available and scientifically studied alternative. It is not a marketing workaround. Several peer-reviewed studies have examined it, and the results are more promising than most people realize.
Where Traditional PDRN Comes From
Conventional PDRN is extracted from the milt (sperm cells) of farmed salmon or trout. The fish are not killed for this process — milt is collected during routine farming — but it is still an animal-derived ingredient. The DNA is then purified through heat extraction until only the polynucleotide chains remain, with proteins, lipids, and any potential allergens removed.
Salmon DNA is used because its molecular structure is highly compatible with human cells. The A2A receptors on human skin cells respond to it almost as readily as they would to endogenous adenosine. This biological compatibility is the scientific basis for PDRN's effectiveness.
What Plant-Derived PDRN Actually Is
Plant-derived PDRN is DNA extracted from plant sources rather than fish. The most studied and commercially available source is Korean ginseng root (Panax ginseng C.A. Meyer). Other sources being explored include matcha (green tea), rice, and Lactobacillus — a fermentation-derived option that could appeal to those avoiding both animal and plant-based harvesting concerns.
The underlying chemistry is the same: fragmented DNA polynucleotide chains that can interact with adenosine receptors and provide nucleotide building blocks to skin cells. The source organism is different, but the active molecular structure is functionally similar.
Does Plant-Derived PDRN Actually Work?
This is the question that matters most. And the honest answer is: yes, based on current evidence — though with some caveats.
A 2023 study published in the International Journal of Molecular Sciences (PMC10649580) tested PDRN extracted from Korean ginseng adventitious root against salmon-derived PDRN in both cell cultures and an artificial skin model (KeraSkin). The results showed that ginseng-derived PDRN activated the same adenosine A2A receptor pathway as salmon PDRN, promoted keratinocyte and fibroblast proliferation comparably, and significantly upregulated the same barrier proteins — fibronectin, filaggrin, Ki-67, Bcl-2, and Cyclin D1.
In plain terms: the ginseng-derived version triggered the same cellular responses through the same mechanism. The researchers concluded it is a viable plant-based alternative.
The 2023 ginseng study used cell cultures and a 3D skin model — not a human clinical trial. There are no published head-to-head clinical trials directly comparing salmon PDRN to plant PDRN in actual patients over time. The mechanism evidence is strong, but the clinical outcome comparison in humans has not yet been formally studied. Plant-derived PDRN is a well-founded, research-backed choice — but "equivalent" in a clinical sense has not been fully proven yet.

The most accessible plant PDRN products come from Korean brands that use ginseng-derived PDRN. VT Cosmetics is the most prominent — their PDRN 100 Essence uses 100,000 ppm of ginseng-derived PDRN and is one of the best-selling K-beauty products of 2024 and 2025. It carries vegan certification and is widely available internationally. For a full breakdown of how essences compare to serums in texture, concentration, and routine placement, see our PDRN essence guide.
On ingredient labels, plant-derived PDRN may appear as: Phyto-PDRN, L-PDRN, Ginseng PDRN, Panax Ginseng DNA, or simply Polydeoxyribonucleotide without source specification. If vegan status matters to you, look for explicit vegan certification on the packaging or check with the brand directly about their PDRN source.
Matcha-derived PDRN products are also emerging — these tend to have a lighter antioxidant profile alongside the PDRN activity, which may suit oily or combination skin well. Rice-derived and fermentation-derived options are available from smaller brands but less widely distributed.
How Plant PDRN Compares to Salmon PDRN in Practice
Based on current evidence and community experience, plant-derived PDRN delivers meaningful hydration, barrier support, and anti-inflammatory effects comparable to salmon-derived PDRN in topical applications. The community consensus broadly echoes the research: both work, salmon has the longer track record, but plant-derived is not a second-rate substitute. For guidance on building a full PDRN routine, see our PDRN serum guide for format and concentration details.
Where salmon PDRN may still have an edge is in injectable applications — the pharmaceutical injectable products approved in Italy and South Korea are all salmon-derived, and the long clinical history for injections is built on that source. For topical products, the distinction matters less, and the plant-derived options are genuinely competitive.
Is Reedle Shot Vegan?
VT Cosmetics' Reedle Shot — the spicule product most commonly paired with PDRN serums — uses sea sponge-derived spicules (Spongilla lacustris). Sea sponges occupy a grey area in vegan ethics: they are animals (technically porifera, the most primitive animal phylum) but have no nervous system, no sentience, and no capacity to experience pain. Many vegan certifications do not exclude sea sponge-derived ingredients; others do. If this matters to you, check the certification standard your brand uses rather than relying on a blanket "vegan" claim.
Summary: Vegan PDRN Is a Real, Researched Option
If you are vegan or vegetarian and interested in PDRN skincare, you do not have to sit this trend out. Plant-derived PDRN — particularly ginseng-derived — is backed by peer-reviewed research, widely available from reputable Korean brands, and performs comparably to salmon PDRN in topical applications. The clinical injectable evidence base is built on salmon PDRN, but for at-home use, the plant-derived versions are a legitimate and well-founded choice.
