₩ is the Korean store price; $ is what Olive Young Global lists. They often differ because the pack size or count sold overseas isn't the same — check the size on the listing before you buy.
Not a cart — nothing is sold here. I check it against what you already use: clashing actives, doubling up, and morning vs night.

About this product
Think of this as an overnight top-up: a niacinamide serum-mask hybrid with chlorella extract and sodium hyaluronate to hydrate and calm while you sleep. The lightweight, jelly-serum texture sinks in without pilling, so it doubles as a smoothing pre-makeup step too. Reviewers consistently report waking up to smoother, more radiant skin, plus better makeup grip when it's worn underneath base products, and note it feels gentle even on easily irritated skin.
Bottom line: a low-effort way to bank hydration and glow overnight.
Smooth a generous layer over the face at night after your usual skincare, patting gently until absorbed — no rinsing needed.
What reviewers say
This is the one I slather on before bed when my skin feels parched: a niacinamide-rich serum built for hydration first, soothing second. It's gentle enough that I don't think twice about using it every night, and I wake up with that plump, well-rested look.
Asked which skin it worked for, 47% of reviewers picked combination (dry 45%, oily 7%).
79% called it gentle on their skin.
These add up to 100 — it's which answer people chose, not a score out of 100. It tells you who liked it, which isn't the same as what will suit you.
