## Key benefits

- Three hyaluronic entries, from full-size to hydrolyzed, share the load
- Gluconolactone and lactobionic acid add a mild PHA-class polish
- Panthenol keeps the formula comforting for reactive skin
- A viscous texture that leaves skin supple, not sticky

## How it works

Skin stripped by actives or dry indoor air feels tight rather than simply dry. A heavy cream alone can sit on top without solving that. This ampoule instead layers three hyaluronic forms, sodium hyaluronate, hyaluronic acid and hydrolyzed hyaluronic acid, alongside panthenol and two mild acids, gluconolactone and lactobionic acid, to hold water at the surface. Skin feels cushioned rather than tight between other steps with repeated use. Apply to damp skin after toner and seal it in with a moisturizer.

## How to use

1. Use the Hydrium Triple Hyaluronic Moisture Ampoule after toner and before moisturizer, morning and evening.
2. A few drops pressed over the face and neck with flat palms rather than rubbed around.
3. Toner first, this second, then a cream over the top within a minute while the layer is damp.
4. Twice a day, every day. Do not leave it as the last layer; a water step with nothing over it dries off and takes the water with it.

## FAQ

### What is the Hydrium Triple Hyaluronic Moisture Ampoule meant to do for skin?

This ampoule leads with water, glycerin and butylene glycol, then carries three separate hyaluronic forms further down the list: sodium hyaluronate, hyaluronic acid itself and hydrolyzed hyaluronic acid, each a different molecular weight, which changes how the moisture is held at the surface. Panthenol sits alongside them for comfort, while gluconolactone and lactobionic acid, both PHA-class humectant acids, close out the list. Together the formula is built to hold water at the surface rather than to resurface or brighten.

### Is this ampoule suitable for reactive or fragrance-sensitive skin?

Fragrance, essential oil and added colourant are all absent from the ingredient list, and there is no silicone or denatured alcohol in the formula either, which matters for anyone who reacts to scent or a filmy finish on the skin. Sulfate surfactants and mineral oil are also missing, since this is a leave-on ampoule rather than a cleanser. That does not make it hypoallergenic, but the list itself carries none of the usual irritant flags.

### Will results build gradually or show up overnight?

Hydration from humectants like the hyaluronic forms here works by holding water already present in the upper layers, so the plumped, cushioned look tends to read within the same use and then compounds with consistent daily application over weeks. It is not a formula built around a single dramatic change, and skipping days will show up as skin feeling thirstier again rather than as lost progress. This is an ongoing daily habit rather than a one-time fix.

### Can I layer this ampoule with a brightening serum or SPF?

The ampoule's own list is limited to hydrators, humectant acids and panthenol, with nothing on it that would conflict with a separate vitamin C or sunscreen step, though every combination should be judged by what is actually on each product's own label rather than assumed. A common order is toner, this ampoule while skin is still damp, then any treatment serum, moisturizer and sunscreen last in the morning. Patch test any new pairing first.

### How can I tell this is the real Korean-market Hydrium formula and not a US repackage?

This unit carries its original Korean-market barcode, 8809598450653, intact on the box rather than a US sticker over it. COSRX runs its own verification rather than leaving it to any seller: open the batch check page on cosrx.com and type in the batch number and expiration date printed on your unit, reading them straight off the package rather than taking a seller's word for it. That check is the same one COSRX offers every buyer of this ampoule.
