PDRN

Polydeoxyribonucleotide (PDRN) (CAS No. 100403-24-5) is a biologically active compound composed of low-molecular-weight DNA fragments extracted primarily from salmon (Oncorhynchus mykiss or Oncorhynchus keta). It is widely used in medical aesthetics, dermatology, wound care, and regenerative medicine for its proven ability to promote tissue repair, cell regeneration, and anti-inflammatory effects. PDRN is a key active ingredient in injectable skin boosters and regenerative skincare products.
