Salmon‑derived PDRNPolydeoxyribonucleotide
For procurement of salmon PDRN raw materials, confirm application grade, molecular weight parameters and packaging specifications prior to purchase. It applies to R&D of skincare substrates, aesthetic-related and biomedical formulations. Xi'an Wanlv offers precise graded supply, full batch documents (COA/MSDS), sample testing and end-to-end inquiry support.
Overview
What is salmon‑derived PDRN raw material?PDRN stands for Polydeoxyribonucleotide. It is DNA nucleic acid fragments obtained by extraction, purification and hydrolysis from male salmon testes, a skin‑conditioning active ingredient.
What is the optimal molecular‑weight range of active PDRN?Recommended molecular‑weight range for cosmetic topical use: 50‑1500 kDa; low‑molecular‑weight fraction 50‑200 kDa favors penetration and distribution on skin surface.
What is the difference between PDRN and PN?PDRN consists of shorter DNA fragments; PN(Polynucleotide) refers to longer‑chain nucleic‑acid fragments, differing in molecular‑weight, bio‑activity and application.

Product FAQ
What is PDRN? What is its INCI name?
PDRN stands for Polydeoxyribonucleotide. Its cosmetic INCI name is Sodium DNA. It is extracted from deep‑sea salmon testes and is a mixture of DNA fragments. It shares high homology with human DNA base sequences and exerts repairing and soothing effects via the adenosine A2A receptor pathway.
What are the differences between PDRN and PN?
PDRN has a molecular weight of 50‑1500 kDa, focusing on anti‑inflammatory redness relief and skin barrier repair. PN is longer‑chain polynucleotide with higher molecular weight, focusing on collagen regeneration and moisturizing effect. They differ in molecular weight and functional focus and cannot be directly substituted for each other.
What are the core benefits of PDRN?
Anti‑inflammatory & redness relief, skin barrier repair, post‑procedure soothing, anti‑oxidation and photo‑damage improvement. It helps boost fibroblast activity. Cosmetic products shall not claim injectable‑grade regenerative or filling effects.
Is Sodium DNA (PDRN) listed in China’s cosmetic ingredient inventory?
Under INCI name Sodium DNA, it is included in the Inventory of Existing Cosmetic Ingredients. It can be legally used for topical cosmetics. There is no mandatory dosage limit in China, yet finished products require comprehensive safety assessment.
