PDRN has become one of the most widely discussed ingredients in Korean skincare, appearing in everything from serums and ampoules to masks and sunscreens. Known for its ability to support hydration and improve overall skin vitality, PDRN is often featured in products designed to promote a smoother, healthier-looking complexion.
While originally associated with salmon-derived skincare, modern formulations now include plant-based alternatives sourced from ingredients such as rose, rice, and seaweed.
What is PDRN?
PDRN stands for Polydeoxyribonucleotide, an ingredient commonly used in skincare to support skin hydration, recovery, and overall skin health.
Traditionally derived from salmon DNA, PDRN is valued for its skin-conditioning properties. As interest in vegan and plant-based skincare has grown, brands have also developed alternative forms of PDRN using ingredients such as rose, rice, and seaweed extracts.
While plant-derived PDRN alternatives are not identical to traditional salmon-derived PDRN at a molecular level, they are formulated with similar goals in mind, helping support hydration, skin vitality, and overall skin comfort.
