Pharmaceutical Grade Salmon PN CAS 9007-49-2/68938-01-2
PN (Polynucleotide, CAS No. 9007-49-2) is a natural macromolecular DNA polymer derived from pure natural salmon testicular tissue through rigorous purification. Sharing over 98% structural similarity with human DNA, PN exhibits excellent natural skin affinity, leaves no residues after application, and allows for long-term safe use. Featuring a higher molecular weight and larger molecular structure than PDRN, PN possesses a stable three-dimensional scaffold structure that delivers reliable physical filling performance. Its slow degradation profile also enables sustained and long-term skin improvement with outstanding safety and stability.
