₩ 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
Formulated at a skin-friendly pH4.5, this serum pairs niacinamide with gluconolactone, a gentle PHA, to support tone and lightly resurface skin without the harshness of stronger acids. Betaine helps keep it comfortable, and it's fragrance-free throughout. Best for combination skin that wants gentle exfoliation alongside soothing, barrier-conscious ingredients. Where it fits: after cleansing and toner, before moisturizer.
Apply a few drops to the face after toner, morning and/or night, following with your moisturizer.
What reviewers say
This is a gentle one, the pH4.5 formula and PHA combo mean I never get that tight, over-exfoliated feeling. Niacinamide rounds it out nicely for tone. It's become my go-to for weeks when my skin is a little touchy but I don't want to skip actives entirely.
Asked which skin it worked for, 64% of reviewers picked combination (dry 24%, oily 12%).
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.
