A deeply hydrating, skin‑soothing sheet mask that infuses your skin with moisture and restorative benefits using birch sap and hyaluronic acid. This “ampoule in a mask” combines the power of botanical hydration and modern formulation to deliver a rich dose of moisture in a gentle, breathable format.

By blending Betula platyphylla japonica juice (birch sap at 9,900 ppm) with a moisture‑locking formula that includes sodium hyaluronate, allantoin, and caffeine, the mask works to revitalize, soothe, and refresh the skin. The birch sap is rich in amino acids, minerals, antioxidants, and vitamins, which helps support the skin barrier, calm irritation, and promote a healthier glow. 

The watery, non-sticky essence (ampoule-like serum) penetrates quickly into the skin without leaving a heavy residue, while the cotton sheet creates a close, comfortable fit that supports absorption. The mask is made from 100% pure cotton and free of synthetic fragrances or harsh additives, making it well suited for sensitive and all skin types.
