PDRN in Skincare: What Salmon DNA Does for Your Skin

PDRN, often called "salmon DNA", is an ingredient used in skincare to support the skin's own repair and regeneration. It is one of the most talked-about skincare ingredients of 2025 and 2026, valued for helping tired, stressed or compromised skin recover and look healthier.

What is PDRN?

PDRN stands for Polydeoxyribonucleotide. It is a fragment of DNA, most commonly sourced from salmon, which is where the nickname "salmon DNA" comes from. In skincare it is used because it is highly compatible with human skin and is associated with supporting the skin's natural recovery processes.

What does PDRN do for the skin?

PDRN is best known as a regenerative, soothing ingredient. It is used to help the skin bounce back after stress, to support a comfortable, hydrated feel, and to make skin look fresher and more even. Because it is gentle, it suits skin that feels tired, dull or in need of recovery.

Why PDRN and copper peptides work well together

Online, the pairing of PDRN with copper peptides (GHK-Cu) is often described as a "regenerative duo": PDRN supports recovery while copper peptides support firmness and skin quality. Cleenlab combines both in a single serum, so you get the pair in one step rather than layering two products.
