This face brush does not rotate like more basic products – it cleans your skin by sonic vibration technology. The Hangsun SC100 Facial Brush can remove the dirt and sebum hidden in your skin’s pores. Ultrasonic cleaning is a sonic micro-vibration massage process created by sound waves that are transmitted at frequencies of over 300 vibrations per second, making for a powerful effect that is 7x better than hand-washing. It also helps follow-up skincare products sink properly into your skin. Continued use of this cleanser can refine pores, smooth wrinkles, improve complexion and make the skin smooth and bright.
