This is the cordless heated gua sha—an ancient Chinese facial tool—that strokes skin to help increase circulation, reduce wrinkles, decreases puffiness, and boost skin’s natural radiance. The device’s head is made with Bian stone, a common material in traditional Chinese medicine that pre-dates the Han dynasty. Combining ancient remedies with modern technology, the unit has three adjustable heat settings and provides three vibration massages that help stimulate lymphatic vessels to flush toxins and improve your face’s natural complexion. Charges via USB-C; a full charge provides up to 2 hours of power. Head 3 1/4" W.
