cosrx Hydrium Centella Aqua Soothing Ampoule 40ml

An ampoule made for skin that flushes, reacts, and craves hydration without making things worse. Forty millilitres of a formula built around a careful balance: calming without weighing down, hydrating without suffocating. The first thing you notice is what you don't feel.

Texture and ingredients — The formula is built on 42% Centella Asiatica Extract combined with Madecassoside — two centella-derived compounds with a well-documented soothing effect on sensitive and reactive skin. Panthenol (vitamin B5) works as a hydrating, restorative and anti-inflammatory ingredient, and is the standout active across the Hydrium range. The ampoule texture — fluid, non-film-forming — comes from a combination of Xanthan Gum and Ammonium Acryloyldimethyltaurate/VP Copolymer, which gives the serum its structure without making it heavy. Allantoin rounds things out for extra tolerance, even on actively breaking-out skin.

How to use it — Two to three drops are enough. Apply to the face after toner and before moisturiser, avoiding the eye and mouth area. The formula absorbs quickly, leaving no sticky residue or greasy feeling — making it easy to layer with other products. It works morning and night, including on spots and blemishes that need moisture but can't handle anything that might cause further irritation.
