## Key benefits

- Absorbs fast with no tack, even on blemish-prone skin

## How it works

An ampoule that is mostly water is bought for what it carries rather than for weight, and this one carries centella asiatica extract with madecassoside, allantoin and panthenol. It goes on after toner and before moisturizer, morning and evening, on skin that is still damp. Skin that reads warm and patchy rather than simply dry is the case it fits, and a heavier cream on its own does not answer that. It is thin enough to layer under another serum if the routine already has one. Twice a day, and the cream over the top is what holds it there.

## How to use

1. Use the Hydrium Centella Aqua Soothing Ampoule after toner and before moisturizer, morning and evening.
2. A few drops pressed over the face, keeping clear of the eyelids and the corners of the mouth.
3. Toner first, this second, then moisturizer while the layer underneath is still damp.
4. Twice a day. Do not add it to a routine with a new exfoliating acid in the same week if skin is already flushed.

## FAQ

### What does the Hydrium Centella Aqua Soothing Ampoule actually contain to calm skin?

Centella asiatica extract sits second on the list, right after water, with madecassoside, one of centella's purified compounds, further down alongside allantoin and panthenol. Chondrus crispus, a red seaweed extract, and sugarcane extract add to the water-holding base, while betaine helps carry moisture without a heavy feel. Together this reads as a soothing-forward formula built on centella rather than a single isolated extract.

### Is this ampoule appropriate for reactive or blemish-prone skin?

There is no fragrance, essential oil or added colourant on the ingredient list, and silicone, denatured alcohol and mineral oil are all absent too, which is generally a lower-irritation profile for skin that flares easily. It is also a water-light gel rather than an oil-based formula, so it does not leave the occlusive film that can feel heavy on blemish-prone skin. Patch testing is still the only way to confirm your own skin's reaction.

### How long before the calming effect actually shows?

Redness and reactivity tend to ease with repeated use rather than in a single application, since centella's purified compounds and allantoin work by supporting the skin's own comfort over time rather than numbing it instantly. Skin under active stress from weather, actives or a new routine typically needs several days of consistent use before it feels calmer. It is a maintenance step, not a rescue product for the same afternoon.

### Can this be layered with a retinoid or exfoliating acid step?

The ampoule's own ingredient list contains no actives that would react badly with a retinol or acid step used elsewhere in a routine, since it is built from extracts, humectants and panthenol rather than exfoliants. A common approach is to use this ampoule on the nights an acid or retinol product is not in rotation, or right after it once skin has calmed. Check the label of whatever else you are combining it with.

### How do I know this Hydrium ampoule is the authentic Korean-market version?

The barcode printed on this unit, 8809598450660, is the original Korean-market code rather than a US label pasted over it. COSRX handles its own authenticity check: go to the verification page on cosrx.com and enter the batch number and expiration date exactly as printed on your box, since reading it off your own unit rather than trusting a seller's claim is how that system is meant to be used.
