ISOI Moisture Dr. Ampoule 40mL (21AD)
아이소이 모이스춰닥터 장수진 수분앰플 40ml
₩ 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
Built around hydrating powerhouses like betaine, trehalose, and squalane, this ampoule is designed for straightforward moisture replenishment rather than treating a specific skin concern. Squalane in particular helps lock in that hydration without a heavy or greasy after-feel, which is why it layers so easily under the rest of your routine. Best for combination skin that wants a reliable, no-frills hydration boost rather than an active-ingredient treatment.
Apply a few drops to clean skin after toner, patting in before your moisturizer.
What reviewers say
I don't need every serum to have a flashy active ingredient — sometimes I just want my skin properly hydrated, and this ampoule does that job well. Squalane and trehalose in the mix mean it feels rich without being greasy, and my skin drinks it up fast.
Asked which skin it worked for, 56% of reviewers picked combination (dry 31%, 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.
