The method is quite simple: 1. Rub toner or water on your skin. 2. Press the "On/Off" key to start the machine. At this time, the indicator light is on, and the blade makes a "squeaking" vibration sound, indicating that the cleaning function is started. 3. Hold the machine by hand and slowly move the shovel blade along the part to be cleaned (bend down). As the shovel blade comes into contact with the skin, water splashes everywhere (if there is not enough water on the skin surface, it needs to be replenished). 4. Wipe the water off your skin with a cotton pad or a clean cloth. 5. Press the "On/Off" key to turn it off.
