It quickly melts waterproof and strongly fixed mascara and removes it neatly in one go. Even on sensitive eye area skin, it is easily removed without rubbing or wiping several times. Before use, shake the water layer and oil layer well to mix, then place a cotton pad on the eye for about 20 seconds and wipe off, resulting in fast and clean cleansing.
