What is PDRN? The viral skincare ingredient called Salmon DNA

PDRN, or polydeoxyribonucleotide, is a trending skincare ingredient gaining significant attention, particularly within the Korean beauty market. Derived from purified DNA fragments, commonly extracted from salmon or trout sperm, PDRN is lauded for its skin-regenerating capabilities.

This ingredient is recognized for its potential to repair the skin barrier, stimulate collagen production, and promote a healthier, more supple complexion. Its popularity has surged as numerous K-beauty brands have launched serums, ampoules, and creams featuring PDRN, often referred to as "salmon DNA skincare."

Originally utilized in medical fields for wound healing and tissue regeneration, PDRN's efficacy in these areas led to its adoption in skincare. Research suggests that PDRN aids in tissue repair processes, reduces inflammation, and stimulates cellular activity crucial for skin regeneration. The DNA from salmon shares a high degree of biological similarity with human DNA, contributing to its good compatibility.

In the beauty industry, PDRN and "salmon DNA" are often used interchangeably, though PDRN refers to specifically processed and purified DNA. Its rise is closely linked to the Korean skincare trend of "regenerative skincare," which focuses on enhancing the skin's natural self-repair mechanisms. Key benefits highlighted by experts include supporting skin regeneration, aiding collagen synthesis by stimulating fibroblasts, and reinforcing the skin barrier, particularly for sensitive or stressed skin. These properties also contribute to its perceived anti-aging effects, making it a sought-after ingredient for those seeking youthful, revitalized skin.
