I normally shave with a Mach3 but trying to use a double edge. I keep cutting myself trying to shave the very upper lip area right under my nose. Is there a method to do this that works since the way I do it with my Mach3 doesn't seem to translate. I pull my nose up and just shave as normal with the Mach3 trying to push in and get the hairs in the crevice there. When I do that with DE I keep getting cut. Any help would be great. Thanks
