Gillette Fusion Power is Gillette's most comfortable shave. After 8 years of shaving innovation and 20 more patents, Gillette Fusion Power is better than MACH3. Gillette Fusion Power is an advanced shaving system with an advanced design that provides optimal performance when using either side of the razor. On the front of the cartridge, Gillette Fusion Power features 5 PowerGlide® Blades spaced closer together to form a shaving surface technology. This design distributes the shaving force across the blades to help reduce pressure, with more comfort and less irritation than MACH3. In addition to more comfort, the 5 Blade Shaving Surface engages more hair more times with successive cutting action, resulting in a closer shave.
