Gillette Fusion features a breakthrough 5 blade Shaving Surface technology on the front of the shaving cartridge. The blades are spaced 30 percent closer together than MACH3 blades. This creates a Shaving Surface that distributes the shaving force across the blades for significantly less irritation and more comfort. Includes an enhanced Indicator Lubrastrip infused with Vitamin E, Aloe and natural oils fades from blue to white, signaling when optimal shave conditions have been reduced. The Precision Trimmer blade, a single blade built into the back of the cartridge, allows men to easily trim sideburns, shave under the nose and shape facial hair.
