In order for the facial mask to work effectively, do not take off the mask until it turns completely transparent and dry on the skin. The drier the mask is, the more obvious the “white spots” will be. Soak the facial mask in water for 30 seconds to 1 minute. If the two actions above have been taken but still the dirt and oil are not showing on the mask, that means the user’s skin is fairly clean, and user can apply the mask less frequently than originally recommended.
