Ever since I started shaving, my upper lip has darkened... now it seems like I always have a mustache, no matter how close I shave (the actual skin is darker :/) It's been a couple of years now, so no, makeup is out of the question. Anyone know what I'm doing wrong? Perhaps I need to go out and actually buy shaving cream? All I do is shave with a Gillette Mach3 with some soap.
