COSRX Centella Blemish Ampule 센텔라 블레미쉬 앰플

⏱ 2 min read
Quick answer: Centella Blemish Ampule is COSRX's ampoule, built around Centella (Cica) and Madecassoside. Oily, combination and blemish-prone skin that flushes easily, and sensitive skin looking for something to layer on a bad week.

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

🌿 Centella (Cica)🍀 Madecassoside

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.

⚠️ Worth knowing: The word blemish in the name does a lot of unearned work — centella is a soothing ingredient with reasonable support for the appearance of redness, not something that clears breakouts. Expect it to make an angry face look calmer, not fewer. It is also so light that it needs a moisturiser over it, and the slight tackiness annoys some people under sunscreen.
