Switch your shave into overdrive. The Gillette Mach3 razor combines sophisticated shaving technologies that work together as a manual system to deliver a close, comfortable shave. It charges your style and makes shaving a high performance activity. The Gillette Mach3 razor combines Gillette 3 Blade Shaving Technology with Anti-Friction blades that gently glide over you. Its pivoting razor head with 10 Micro fins follow every contour on your face for outstanding comfort and closeness. A lubricating strip on the razor head gradually fades to white, to indicate when you are no longer getting an optimal shave. The Gillette Mach3 razor: The triple threat. The Gillette Mach3 razor features an ultra-soft skin guard consisting of 10 thinner and more flexible micro fins. These micro fins precede the blades and smooth out the skin, gently lifting even stubborn hairs before the first blade cuts them. So you get a close, comfortable shave. A Lubra strip is a thin strip that sits at the top of your razor. Releasing lubricants over time provides great glide. When you may no longer be getting an optimum shave, it fades to white, indicating it may be time to change the blade. The Gillette Mach3 has 3 blades positioned progressively to extend gradually closer, so for every stroke you take, it takes three.
