PDRN, or Polydeoxyribonucleotide, is a skincare ingredient derived from salmon DNA, specifically its sperm. This innovative component is celebrated for its ability to enhance skin hydration, firmness, and overall health by activating skin receptors that stimulate cell growth and collagen production. As the glass skin trend continues to thrive, PDRN has gained traction in both Korean and Western markets since its introduction in early 2025. Popular products featuring PDRN include the Anua PDRN Hyaluronic Acid Capsule 100 Serum, which hydrates and plumps the skin, and the Medicube PDRN Pink Peptide Serum, known for its brightening and barrier-strengthening properties. Other noteworthy mentions are the Dr. Althea PDRN Reju 5000 Cream for moisture and elasticity, and the Biodance Caviar PDRN Real Deep Mask for a radiant glow. These products not only promise to improve skin texture but also support skin repair and soothe irritation, making them essential additions to any skincare routine aiming for that youthful, glass-like finish.
