The brightening actives of these mini masks help reduce the appearance of dark spots on the skin, promoting a more uniform complexion. Apply preferably at night on cleansed and dry skin, 3 times a week for 1 month. Open the sachet and remove the protective casing and foil from the mini mask. Press the side covered with 'micro cones' onto the area to be treated with your fingertips and gently feel whether the mask stays in place. Leave it on for at least 3 hours before removing the mask. For best results, leave the mask on overnight.
