Nee, never used! The Evertone Microcurrent Facial Toning Device uses a low-grade electrical current to lift, tighten, tone and contour the facial muscles while also reducing the appearance of fine lines and wrinkles all in only FIVE minutes. With continued use, you will start noticing tightening and lifting in sagging jowls, double chins, and fatty cheeks. Pair it with our EverGlow Activating Serum for best results. Our conductive gel serum has been formulated to enhance the effectiveness of your EverLift Microcurrent Facial Toning Device by activating the electrical currents and allowing your device to glide over your skin easily.
