Does anyone else experience what I have termed Shadow? After I shave even when I really take my time, multiple passes and my face is bbs, or as close to it as I get at this point, I still have a blackish-blue cast on my skin from my beard. I can't feel a thing, but I can see it, this is primarily on my moustace region and chin. Is there anythin I can do about it? Now I should say that I have dark brown hair and very light skin so I know that contributes to the problem.
