To Use: Cleanse skin and remove makeup. Take the mask out of the package, carefully unfold and place the sheet on the face, keeping the eyes and the mouth free. Smooth and arrange mask to ensure the forehead, cheeks, nose and chin are covered. Leave on for 15-20 minutes and remove the mask. Let the skin absorb and receive maximum benefits from the excess serum by patting it into the skin. No need to rinse. Use two times a week or as often as needed.
