Unlike rotary shavers, which use circular motion, each BRAUN shaver moves in straight lines. At Braun, we believe that this is the most intuitive and effective movement with fewer strokes and therefore with lower risk of skin irritation. While the BRAUN Series 3 and later come equipped with blades that glide smoothly over the skin, the BRAUN Series 5 and later also feature a flexible head for maximum contact with the contours of the face. Most of them use Wet & Dry technology in case you prefer using water and shaving foam or gel, and AutoSense to adjust performance to beard density. There's no better shave than with BRAUN.
