COSRX The 6 Peptide Skin Booster Serum 150mL Special Set (+Peptide Serum 30mL)
코스알엑스 더 6 펩타이드 스킨 부스터 세럼 30ml
₩ 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
This one is meant to go on first, right after cleansing, a watery, peptide-and-niacinamide booster serum designed to prep skin so everything layered afterward absorbs better. It's gentle enough for reactive skin: reviewers highlight that despite the light texture, it reaches deep enough to ease that tight, dehydrated feeling rather than just sitting on the surface. The travel-friendly size here is genuinely handy too, small enough to test the formula, or to toss in a bag, before committing to the full bottle.
After cleansing, as the very first step of your routine, smooth a suitable amount over the face and layer it on a few times for fuller absorption.
What reviewers say
This serum is really about hydration for me — the six-peptide, niacinamide blend leaves my skin soft and cushioned rather than tight. I lean on it most on dry or combination skin days, and it's gentle enough that it never fights with the rest of my routine.
Asked which skin it worked for, 46% of reviewers picked combination (dry 44%, oily 10%).
68% 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.
