I always hear that you have to shave with the grain and not against it, but I can never get a smooth shave from that! Not only does it feel grainy, but it looks grainy as well; there's a darkened shadow all over my cheeks and along my jaw. I find that shaving against the grain gives my face a much smoother look (and feel) but I always get some nicks and cuts from this and I'm afraid of getting ingrown hairs. I use Gillette products (a Mach3 blade and their shaving gel) and change the blade every week. I saw one of their videos showing how you're *supposed* to shave, where the guy shaves along his jawline on his cheeks, and vertically down underneath the jaw. So I tried that (not in long strokes like the video showed, I know you're supposed to do short, soft but pressured strokes) and got nowhere with it - the [fresh] blade just seemed to glide over my hairs every time. So I'm clearly doing something wrong and I have no idea what! And for the sake of further discussion, how do you shave/trim/groom your face? What products do you use?
