COSRX Hydrium Triple Hyaluronic Water Wave Sheet Mask 20ml is an essence-soaked Korean face mask designed to replenish moisture in dry, dehydrated and tired-looking skin. The COSRX Hyaluronic Water Mask combines three forms of hyaluronic acid with Centella Asiatica extract to support a soft, plump and refreshed complexion.
COSRX Hyaluronic Water Mask for Dehydrated Skin
This triple hyaluronic sheet mask delivers a concentrated layer of lightweight hydration in 10–20 minutes. Its soft sheet adheres closely to the face, helping the watery essence remain evenly distributed throughout the treatment.
The cooling formula is suitable for all skin types, particularly complexions that feel dry, tight, warm or uncomfortable. After use, the skin feels refreshed and moisturised with a smooth, dewy-looking finish.

Cooling Hydration and Skin Comfort

Triple Hyaluronic Sheet Mask Ingredients
- Triple Hyaluronic Acid: Helps attract and retain moisture for a hydrated and plump-looking finish.
