Overview
A DNA-derived compound, typically sourced from salmon, studied for tissue repair and now emerging in topical skincare.
What it is
PDRN is a mixture of DNA fragments, most often extracted from salmon. It has been used in regenerative medicine — particularly in injectable form — and has recently appeared in Korean skincare serums and ampoules.
It is an emerging ingredient: much of the evidence comes from clinical or injectable contexts, not topical cosmetic use.
How it works
- In clinical studies, PDRN has been studied for stimulating tissue repair via adenosine receptor activity.
- Topical penetration of DNA fragments is limited; cosmetic benefits may relate more to hydration and skin conditioning.
Potential benefits
- Hydration and conditioning in cosmetic formulations
- Interest as a 'skin recovery' ingredient — evidence still emerging
Potential benefits describe what research and use suggest may occur for many people — not guaranteed outcomes. Individual responses vary.
Who might consider it
- Readers following emerging Korean skincare ingredients
- Those curious about regenerative-inspired formulations
How it’s used
- Serums, ampoules, and sheet masks.
Pairing with other ingredients
- Hyaluronic AcidOften formulated together for hydration.
- PeptidesCommon in 'recovery' positioned serums.
Things to know
- Topical evidence is preliminary; injectable evidence does not transfer directly.
- Animal-derived (salmon); not suitable for everyone.
