Sodium DNA

Sodium DNA, particularly in its PDRN (polydeoxyribonucleotide) form, consists of low molecular weight DNA fragments typically extracted from salmon milt or produced through bacterial fermentation. This ingredient is valued in cosmetics for its ability to promote cellular regeneration and wound healing through purinergic receptor activation, making it particularly popular in Korean skincare formulations. Formulators choose it for its documented ability to stimulate fibroblast proliferation and collagen synthesis, with the 0.5% concentration being clinically studied for optimal efficacy in skin repair applications.
