How to Use 1. After cleansing your face, dry off excess water, and use toner to even out the skin texture. 2. Open the package, and place the mask sheet evenly on your face, aligning it based on your eye and mouth areas. 3. Relax for 10 to 20 minutes, and take off the mask sheet. 4. After removing the sheet, gently pat to allow the remaining essence to be absorbed by the skin.
