What is PDRN? A plain guide to salmon DNA skincare

Ingredient guide · Korean skincare

A plain guide to PDRN, and to the P.E.C 360 complex used in the Dr. Richesse Revine series.

What PDRN is

PDRN is often called salmon DNA. In Dr. Richesse products it is patented low-molecular PDRN, which the brand describes as "the beginning of skin regeneration".

PDRN, exosome and collagen together

Dr. Richesse combines three ingredients in its P.E.C 360 complex, which the brand describes as a patented ingredient combination.

✓ PDRN: Patented low-molecular PDRN.
✓ Exosome: ginseng exosomes, which deliver cell regeneration signals and have powerful antioxidant effects.
✓ Collagen: ultra-low-molecular collagen, over 50,000 times smaller than a pore.
