What it does
Regenerative active derived from salmon DNA fragments.
PDRN — short for polydeoxyribonucleotide — is a regenerative active derived from purified salmon DNA fragments. It became one of the most-searched skincare ingredients of 2025, driven by its rise in Korean clinical skincare and at-home serums from brands like Anua and Medicube.
The research case is strong: PDRN interacts with the adenosine A2A receptor, a signalling pathway that promotes collagen synthesis, tissue repair, and anti-inflammatory effects. Clinical studies show it can accelerate wound healing, improve skin elasticity, and reduce the appearance of fine lines and post-inflammatory marks.
In topical skincare, PDRN is best suited to compromised or reactive skin — barrier damage, post-procedure recovery, dullness, and early signs of ageing. It pairs well with peptides, niacinamide, and centella-based calming actives. Most formulas use PDRN at 0.1–2% concentration; position in the top third of the INCI list is a good signal that the concentration is meaningful.
