After washing your face in the morning and evening, or after applying serum, take an appropriate amount (4 to 5 pumps) in the palm of your hand and gently spread it over your entire face. Finally, press it with your palm so as to wrap it around your face. You can use it over and over again until you feel the moisture. You can feel the lotion absorb into your skin and apply it several times for the best effect. Please use it as a moisturizer in the iontophoresis device. Ultrasonic introduction can also be used.
