For a shave tailored to your facial contours, hair thickness, and density, the ES-LV69 utilizes responsive beard sensor technology. This increases the strength where the beard is thick and reduces it in other areas to avoid skin irritation, ensuring an even shave that keeps your skin smooth for up to eight hours. With specially designed five curved blades, it is capable of removing all types of beards: the quick-cut blade is intended for trimming long hairs, the quick-lift blade lifts lying hairs, and the finishing blade cuts longer hairs a second time, closer to the skin.
