PDRN, with INCI name DNA Sodium, stands for Polydeoxyribonucleotide. It is a specific fragment of DNA extracted from the sperm sacs of deep-sea salmon, purified through multiple steps including enzymatic cleavage, depurination, precipitation, and chromatography. Suitable for cosmetics, Class II, and Class III medical devices, it is free of active proteins and peptides, earning it the reputation as the "liquid gold" of medical aesthetic ingredients.
The PDRN extracted from salmon shares up to 98% similarity with human DNA bases. It is a byproduct of protamine insulin injection excipients, with no immunogenicity, high safety, and no risk of nodule formation.
