Use immediately after washing your face. With clean hands, carefully remove and unfold a mask without tearing it. Align the sheet with your eyes first, then your mouth, and fit it closely over your entire face. Leave on for about 5 minutes, then gently remove. Use your palms to work the remaining liquid into your skin. You may also use the mask after applying toner.
Watch for any signs of skin irritation. Stop using if the product does not agree with your skin.
