COSRX Hydrium Triple Hyaluronic Moisture Ampoule
A lightweight hydrating ampoule that stacks three hyaluronic acids with panthenol for dehydrated skin.
What it is
A watery, fast-absorbing ampoule that combines three types of hyaluronic acid (different molecular sizes for surface and deeper hydration) with panthenol and gluconolactone. The lightweight texture is designed to be layered under moisturiser or worn alone on oilier days. Fragrance-light and aimed at dehydrated, combination and oily skin.
What reviewers say
Reviewers love how quickly it absorbs and how plump and comfortable skin feels afterwards, with many calling it a dependable daily hydrator that never pills. It is a frequent favourite for oily and combination skin. The main caveats: it is hydration only, so it does nothing for tone or breakouts, and on its own it is not enough moisture for very dry skin in winter.
What reviewers love
- Three hyaluronic acids for well-rounded hydration
- Very lightweight, absorbs fast with no grease
- Layers cleanly under moisturiser, sunscreen or makeup
- Suits oily and combination skin that dislike heavy creams
Watch-outs
- Hydration only, no brightening or anti-acne action
- Not enough on its own for very dry skin
- Effect is subtle rather than dramatic
Who it's for
| Oily / combination | Weightless moisture without a heavy feel |
| Dehydrated | Multiple hyaluronic acids plump the skin |
| Dry | Great as a layer, but seal with a richer cream |
Key ingredients
- Triple hyaluronic acid: Different molecular sizes hydrate at multiple levels
- Panthenol: Soothes and boosts lasting moisture
- Gluconolactone: A mild PHA that supports a smooth, hydrated surface
How to use it
After toner, apply a few drops to damp skin and press in, morning and night. Follow with moisturiser to lock the hydration in, and sunscreen in the morning. Apply to slightly damp skin for the best plumping effect.
