PDRN is one of the newer ingredients in skincare, but the name often raises questions. In this guide we explain what PDRN is, how it compares to medical uses elsewhere, and where you encounter it at Peptide Lab.
PDRN (polydeoxyribonucleotide) is a collection of DNA fragments used in cosmetic skincare due to its link to skin cell renewal. Peptide Lab's PDRN serum is a cosmetic product for topical use, separate from medical uses that exist elsewhere under other brand names.
What is PDRN?
PDRN stands for polydeoxyribonucleotide: a collection of DNA fragments, typically derived from salmon sperm DNA, purified for use in formulations. It is not a peptide — not a chain of amino acids — but a nucleotide-based ingredient. Read more about the distinction between skin peptides and other skin ingredients in peptides for skin.
Medical uses elsewhere versus the cosmetic serum here
In some countries outside the EU, PDRN is registered under specific brand names as a medical device or medicine for skin and wound applications, administered by medical professionals. Peptide Lab's PDRN Pink Peptide Serum is a different product: a cosmetic formulation for topical use on the skin, without that medical registration or claims in the Netherlands. It is not a medicine and not medical advice.
PDRN within the skincare category
Like copper peptides (GHK-Cu), PDRN exists in two worlds: cosmetic formulations and, elsewhere, medically regulated uses. Read the full distinction between cosmetic and research-grade in copper peptides: cosmetic vs research, or browse the skincare & serums category.
This information is general and educational. Peptide Lab's PDRN serum is a cosmetic product for topical use on the skin, not a medicine and not a medical device in the Netherlands. Not medical advice.
Frequently asked questions about PDRN
What is PDRN?
PDRN (polydeoxyribonucleotide) is a collection of DNA fragments, typically derived from salmon sperm DNA. It is not a peptide, but is often offered alongside copper peptides and other skincare ingredients due to the overlap with skin research.
Is PDRN approved for medical use in other countries?
In some countries outside the EU, PDRN is registered under specific brand names as a medical device or medicine for skin and wound applications. Peptide Lab's PDRN serum is a cosmetic product, formulated for topical use, without that medical registration or claims in the Netherlands.
Why is PDRN mentioned in skin research?
In research, PDRN has been linked to skin cell renewal processes. These descriptions come from cosmetic ingredient literature and preclinical research, without medical claims.
Is Peptide Lab's PDRN serum the same as research-grade material?
No. The PDRN Pink Peptide Serum is a cosmetic product for topical use on the skin — not a research-grade powder for laboratory use, unlike, for example, research-grade GHK-Cu.
