What distinguishes the COSRX 5 PDRN serum
By the Korean PDRN editorial team · research-based, not a hands-on test · Updated 05/11/2026
This serum and the matching toner share several ingredients, including niacinamide, panthenol, Sodium DNA and multiple forms of hyaluronic acid. The serum starts with a different blend of glycols and lists hydrolysed collagen earlier in its formula. The ordering alone cannot tell you which product contains more PDRN or which will suit your skin better.
COSRX lists the 100 mL and 50 mL sizes on the same product page. Costco UK lists the 100 mL pack. The ingredients here come from COSRX’s global declaration, so use the label on your own pack to check the exact formula.
