PDRN (polydeoxyribonucleotide) is a medically recognized compound derived from salmon DNA—often designated in Korea as "sodium DNA"—and shares up to 80% similarity with human DNA. Known for its regenerative and anti-aging properties, PDRN has been extensively used in clinical settings for wound healing, burn treatment, and skin repair. It stimulates new tissue growth, promotes collagen synthesis, and enhances overall cellular regeneration. These effects are not theoretical—they are substantiated by empirical research and clinical application. Its properties are also anti-inflammatory and ideal for sensitive, aging, or compromised skin types.

At Dr. Ellie’s private practice in Los Angeles, PDRN is not a superficial or trend-driven treatment but a core component of her regenerative skin protocols. It is applied in cases of post-procedural recovery, hormonal aging, volume loss, and inflammation from acne or environmental stress. By integrating PDRN with Eastern medical principles, Dr. Ellie promotes the skin’s innate healing processes, offering long-term results without reliance on synthetic fillers or invasive procedures.

PDRN binds to cell receptors and activates fibroblasts—the cells responsible for producing collagen and elastin—naturally boosting skin firmness and elasticity. Its low molecular weight allows it to penetrate deeply, delivering hydration at the molecular level by plumping the skin and locking in moisture. Additionally, PDRN has anti-inflammatory properties that help calm redness and strengthen the skin barrier, making it especially effective for sensitive or compromised skin.
