by COSRX
Updated September 22, 2026
Hyaluronic acid and panthenol hydration toner; layers fast and feels featherlight.
What the community says
A watery hydrating toner built around hyaluronic acid, glycerin, panthenol, and allantoin. It suits dehydrated or barrier-stressed skin that wants a light first layer, but eczema-prone or easily irritated skin may hate it.
What this means for you
What people love
Watch out for
- Can sting or flare eczema-prone skin
- Too plain if you want more than hydration
- Not a dead-simple fix for severe dehydration
