Definition & OriginPDRN (Polydeoxyribonucleotide) is a polynucleotide complex composed of DNA fragments (50–2000 base pairs), typically purified from salmon DNA.Originally used in medical treatments (wound healing, burns, ulcers), it has recently gained popularity in cosmetic and dermocosmetic formulations under the name “salmon DNA.”Key Skin BenefitsCell Renewal & RepairPDRN activates fibroblasts, increasing collagen and elastin production, leading to improved firmness, reduced fine lines and wrinkles, and smoother skin texture.It supports DNA repair mechanisms, accelerating regeneration in acne scars, surgical scars, and post-procedure recovery.Hydration & Barrier SupportPDRN enhances cellular moisture retention and supports hyaluronic acid production, helping the skin appear more plump, hydrated, and radiant.It strengthens the skin barrier, reducing dryness, tightness, and sensitivity, and provides long-lasting, deep hydration.Anti-Inflammatory & Soothing EffectsBy suppressing pro-inflammatory cytokines (such as IL-1 and TNF-α), PDRN helps reduce redness, irritation, and sensitivity.This makes it suitable for sensitive skin, rosacea-prone skin, and post-procedure care (peels, lasers).Brightening & Tone EvennessPDRN helps regulate melanocyte activity and melanin production, offering tone-evening benefits for sun spots, age spots, and melasma.With regular use, skin appears more even, luminous, and radiant.Antioxidant ProtectionIt helps reduce oxidative stress caused by free radicals, protecting the skin against UV damage, pollution, and premature aging.Who Is It For?PDRN is commonly used to address aging signs, dryness, barrier weakness, dullness, acne scars, and sun damage.Thanks to its high biocompatibility, it is well tolerated by dry, normal, combination, mature, and sensitive skin types, making it a versatile regenerative active.
