Microtree Sonic Facial Cleansing Brush System, Waterproof, Wireless Charging, Smart Face Cleansing Brush, White - Face Cleansing Brush-White

• A two-year warranty (free returns) : This is what you want：It is on the basis of the old model of MIA 2 upgrade, and you'll have two years to verify what I have described. Wireless charging: It's proven to be easier and more waterproof, so feel free to use it in the shower, and it lasts for 30 days on a single charge. Ultrasound technology: we have upgraded the ultrasound from 156Hz to 250Hz. The high-frequency vibration helps you remove dirt, oil and cosmetics residue, and dresses pores. The brush head will not rotate, so there is no need to worry about damaging the facial skin. Each brush head is rounded and has long, soft bristles, which gives you an extremely comfortable experience during the cleansing process, which cannot be matched by the silicone brush head. In addition, the brush head is universal with the old Sonic brush head.
