PDRN, or polydeoxyribonucleotide, is a bioactive DNA-based ingredient known for supporting skin renewal, tissue repair and wound healing. The ingredient consists of BIO-fragments that can help to stimulate cell regeneration, collagen production and repair processes in the skin. PDRN is currently used in advanced cosmetics, aesthetic treatments and regenerative applications, particularly where the aim is to improve skin quality, reduce signs of ageing and support the healing of damaged tissue. Havdis develops PDRN from Atlantic cod, a marine by-product from the Norwegian fisheries industry, transforming biomass into a bioactive ingredient with full traceability.
