코스알엑스 더 레티놀 0.1 크림 20ml
₩ 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
Retinol works by speeding up cell turnover and signaling collagen production, which over time smooths texture, refines pores, and softens fine lines — but it's also notorious for irritation when you start too strong. COSRX keeps the concentration at a beginner-friendly 0.1%, cushioned with shea butter, trehalose, and vitamin E so the adjustment period feels gradual rather than harsh. Reviewers who eased in — every other night for the first two weeks before going nightly — report smoother texture, tighter-looking pores, and better firmness without the usual peeling. Best for retinol beginners who want real results without jumping straight to a stronger, prescription-strength formula.
Refrigerate after opening, then start every other night for the first two weeks with a rice-grain-sized amount on target areas, building up to a pea-sized amount over the full face nightly from week three onward.
What reviewers say
This is where I'd start anyone curious about retinol: a 0.1% concentration paired with vitamin E and trehalose to soften the adjustment. I go to it purely for aging and brightening concerns, it's not the most cushiony formula so I'd build up tolerance first, and combination skin seems to take to it best.
Asked which skin it worked for, 62% of reviewers picked combination (dry 23%, oily 15%).
41% 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.
