COSRX Centella Blemish Ampule 센텔라 블레미쉬 앰플
A thin, watery centella ampoule built for skin that is irritated rather than dry — the 진정 (jinjeong, soothing) end of the COSRX range rather than the exfoliating end. Centella asiatica extract and its isolated fractions carry the formula, with very little else doing anything: no acids, no fragrance-forward finish, no heavy emollients. It is deliberately unexciting, which is the point of a product you reach for when your face is already annoyed.
What it is built around
Who it suits
Oily, combination and blemish-prone skin that flushes easily, and sensitive skin looking for something to layer on a bad week. It sits well over an acid or retinoid routine on the nights you skip them. If your main problem is dryness rather than redness, this will not do much — there is almost no moisturising weight in the bottle.
How to use it
After cleansing and toner, before your moisturiser, morning or evening. A few drops pressed over the whole face, or dabbed just where you are red. It absorbs in seconds and layers under anything. Nothing here conflicts with actives, so it works fine as the calming layer on nights you use something stronger.
