I've been trying to work on my shaving skills, and I've thing that I've noticed is that, when I shave my face, the areas where the hair used to be are darker than the rest of my face. I haven't really noticed too much of this on the rest of my body, so is there some reason behind this? (In case it helps, I have brown hair, and the dark areas kind of have a greyish-er tone than the rest of my skin.) Also, is there any way I can get rid of this short of using foundation (which I don't want to do because I have really bad acne)?
Thanks in advance for any advice.
