Discover true smoothness with Braun’s 5 53B replacement head. New blades are crucial when it comes to ensuring a clean, accurate and irritation-free shaving experience, which is why Braun recommends getting a new attachment every 18 months. Performance can become weaker as the blades become blunt, increasing the risk of redness and coarseness. One quick change restores your razor to its peak level of performance, allowing the blades to glide effortlessly over your visage, leaving sumptuous softness in their wake.
