Shaving System with Three Blades. It gives you the closest shave you've ever had in fewer strokes. DLCA Comfort Edges are patented. Each blade has a patented DLC comfort edge, allowing the Gillette MACH3 to glide smoothly across your face. Features: Gillette SkinGuard Razor is a ground-breaking product introduced by Gillette. Not every man's skin is the same, and if you have acne on your face, sensitive skin, or simply worry about the impact of multi-blade razors on your skin, you should avoid using them. The unique SkinGuard in between the blades shaves without damaging your skin. The SkinGuard is positioned between the blades in such a way that it works to minimise tug and pull and cuts hair at skin level, thereby minimising contact between your skin and the blades.
