Salmon DNA Skin Care is Gaining Popularity: What’s the Hype?

Salmon sperm, specifically PDRN (polydeoxyribonucleotide), has recently gained attention as a prominent skincare ingredient on TikTok. PDRN, derived from salmon sperm DNA, is known for its ability to repair skin due to its similarity to human DNA. It stimulates collagen production, new blood vessel formation, and improves skin elasticity, resulting in firmer and more elastic skin.

Originating over a decade ago in South Korea with products like Rejuran, PDRN has become popular in the U.S. as K-Beauty trends rise online. Brands like Medicube have capitalized on its popularity, endorsed by celebrities to achieve “glass skin.” While widely considered safe, those with fish allergies, pregnant or breastfeeding individuals, and those with certain health conditions are advised to avoid it.
