How the COSRX hydrogel format differs
By the Korean PDRN editorial team · research-based, not a hands-on test · Updated 05/11/2026
The mask is a 34 g sheet held together by ingredients such as carob gum, carrageenan-containing algae and agar. Glycerin and niacinamide appear early on the maker’s declaration, while Sodium DNA appears later. COSRX Korea confirms the weight per sheet. The UK single-sheet listing shows the same ingredient sequence. This is a separate formula from the brand’s 5 PDRN serum and toner.
