How to use
Use approximately 1-2 times a week. Use after toning your skin with lotion. Can be used morning or night. 1: Hold the handle with your right hand and slowly unfold the mask. Be careful not to drip. 2: With the handle on the right hand, align the mask with your eyes and mouth and press it firmly against your skin. 3: Then, while lightly pressing the notch under your chin, hold the cheek area and pull each side up toward your temples, overlapping the mask to seal it in place. 4: Leave the mask on for 10 minutes, then remove it and rub any remaining liquid into your skin with your palm. For hygienic reasons, do not reuse a mask once used. The mask is water-insoluble, so do not rinse it. Do not store in high temperatures or in direct sunlight. Keep out of reach of infants and young children. Use as directed. Avoid overly wide areas and frequent use. When using in combination with other whitening cosmetics, use each product at a time, monitoring the condition of your skin.
