Use after cleansing and toning your complexion. Fold the lower pouch over three times and push it up until it pops open and penetrates the sheet mask. Apply the sheet mask to your face, making sure that it adheres well to your face, and then conform to the contours of your face. After 15-20 minutes, remove and pat the remaining essence gently on the face for better absorption. Then continue with the rest of your skin care regimen.
