COSRX Hydrium Triple Hyaluronic Moisture Ampoule
A lightweight hydrating ampoule that quenches thirsty, dehydrated skin without any sticky feel.
What it is
A watery, quick-absorbing ampoule that combines three types of hyaluronic acid to hydrate at different levels, plus a soothing, moisture-boosting ingredient and a touch of mild exfoliant to keep skin smooth. The lightweight texture sinks in without stickiness and is meant to sit under moisturiser, or be worn alone on less-dry days. It leans best for dehydrated and thirsty skin, but combination and oily skin like it too because it never feels heavy.
What reviewers say
Reviewers love how fast it absorbs and how plump and comfortable skin feels afterwards, and many call it a dependable daily hydrator that never pills or feels sticky. Dehydrated and sensitive skin are the happiest. The honest notes: it is hydration only, so it does nothing for tone or breakouts, a few feel it is not that different from other hyaluronic acid serums, and it is a little pricey for the bottle size.
