Why it's on the Korean shelf
A regular in Olive Young Korea's top 30. The overnight hydrogel mask that goes on milky and turns clear as it absorbs — the single most-filmed K-beauty product of the last two years, and still on the Korean shelf.
Who it's for

Honest note
Needs 3+ hours (ideally overnight) to work; it is not a 15-minute mask.
