What it is
This sheet mask gently envelops dry skin when you're concerned about dryness caused by air conditioning or seasonal changes. It contains three moisturizing ingredients (potassium lactate, calcium lactate, and magnesium lactate) that combine lactic acid with minerals. By combining minerals that are difficult for skin to absorb on their own with lactic acid, it efficiently delivers minerals to the stratum corneum, supporting the skin's barrier function. A special once-weekly treatment will lock in moisture and leave your skin feeling smooth and refined. The Tuning Line: This aromatic woody fragrance tunes your mind with a pleasant, fragrant skincare routine. The gentle fragrance of geranium and lavender blends with the rich woody notes of myrrh and cypress, and the refreshing scent of yuzu.

How to use
1. Remove the mask from the bag and unfold it as shown in the diagram. Fold the eye section of the sheet outward. (*Please use on clean skin after washing your face.) 2. Place the mask on your face, aligning your eyes and mouth, and make sure it fits snugly without any air bubbles. Fold the slits in the mask over to fit your face. 3. When caring for the eye area, make sure to cover your eyes with the folded section. (*When using on the eyes, be sure to close your eyes to prevent the liquid from getting into your eyes. If you wear contact lenses, remove them before use.) 4. After approximately 5 to 10 minutes, remove the mask and massage any remaining serum into your skin.
