How the COSRX PDRN toner fits into a routine
By the Korean PDRN editorial team · research-based, not a hands-on test · Updated 05/11/2026
The 280 mL toner is the first leave-on step in the COSRX 5 PDRN range. Its list puts butylene glycol, glycerin and niacinamide ahead of Sodium DNA. It also lists panthenol and several forms of hyaluronic acid. If you already use a hydrating toner, the ingredient list is a better basis for comparing the two than the number of named PDRN sources.
COSRX describes a blend that includes salmon and other sources. The exact share of each is undisclosed. The 280 mL UK Boots listing reproduces the maker’s ingredient sequence. Check the pack for the formula you are buying. This profile is based on the listed formula rather than hands-on use.
