ROUND LAB Birch Moisturizing Sheet Mask | Hydration-Locking & Cooling Mask by Masksheets

Effortless hydration with a clean, cooling touch

From the pristine landscapes around Inje, Round Lab crafts a Birch Moisturizing Sheet Mask designed to deliver immediate relief to dry skin. The star pairing of Inje birch sap and hyaluronic acid helps lock in moisture, while a refreshing, watery texture keeps the experience light and comfortable. The formula remains fragrance-free and free from heavy additives, making it a friendly option for sensitive skin.

What makes it stand out

A high concentration of Mugwort Extract (91.45%) provides nourishing notes and a calming look to the skin. The mask is unscented and gentle, allowing for routine use without overpowering scents. The lightweight sheet and serum deliver moisture without heaviness, leaving skin feeling refreshed rather than overwhelmed.
