PDRN CareThe Science of Skin Regeneration
PDRN Care is the definitive resource for PDRN — the DNA-derived biopolymer transforming regenerative dermatology. Explore products, clinical evidence, and treatment protocols.
What is PDRN?
Polydeoxyribonucleotide (PDRN) is a DNA fragment mixture extracted from salmon or trout sperm, with a molecular weight of 50–1,500 kDa. It activates the adenosine A2A receptor pathway, promoting tissue repair, anti-inflammation, and angiogenesis.
DNA Extraction
Purified from Oncorhynchus mykiss (salmon trout) sperm via patented extraction process
Fragmentation
DNA chains are fragmented to 50–1,500 kDa for optimal bioavailability
A2A Activation
PDRN activates adenosine A2A receptors, triggering cellular regeneration cascades
Tissue Repair
Stimulates fibroblast proliferation, collagen synthesis, and angiogenesis
