One serum says “Salmon PDRN,” the next says “Rose PDRN,” and a third is advertised as vegan. The names sound clear, but they are only so when the origin and complete recipe are proven.

Why salmon is often mentioned

Classic cosmetic PDRN or sodium DNA can be obtained from fish components. For the Medicube PDRN Pink Peptide Serum , the recipe mentions not only Sodium DNA but also Milt Extract and Salmon Egg Extract. This specific variant is therefore not a vegan choice.

What plant PDRN can mean

Some manufacturers use DNA fragments from plants, such as roses or rice. “Plant PDRN” first describes the advertised source of this ingredient. This does not automatically mean that every other element of the recipe is vegan. Even the name Sodium DNA alone does not reliably tell you the source.

Is one origin more effective?

No certain superiority can be derived from “salmon” or “rose” on their own. Concentration, size of the fragments, stability and the rest of the formulation play a role. The data available for applied cosmetics is also much more limited than some advertising suggests.

How to make a transparent choice

If vegan cosmetics are important to you, look for a clear statement from the manufacturer about the entire formulation . Also check whether it contains fragrances or other ingredients that are relevant to you. Our article PDRN, collagen and peptides in comparison helps with the technical classification; for a single INCI name you use Understanding Ingredients .

If the origin of a specific product remains unclear, you can ask via Ask Thu . Then we check exactly this variant instead of guessing from the color of the bottle or a plant name.
