I'm sorry dude, I gotta bring this up - we used to have a student geography teacher and we were one of the nasty, older classes. This guy didn't have acne (I personally would never poke fun at anyone for that) but he did have a beard. The thing is his beard was ginger and his hair was dark brown!! What was that about? I mean the beard was full on orange. Unfortunately the guy was also called Mr. Rankin and he had a speech impediment that meant he almost pronounced his 'R's as 'W's. Now, call me and my ex-classmates immature but ever since he introduced himself we couldn't take him seriously
I hope it's not as bad for you. Incidentally, I find that younger kids are more annoying when it comes to remarking about my acne. I didn't have to put up with much stick from my peers (including people who didn't like me) about it at school (where you'd get picked on for wearing the wrong clothes), but when I worked on a children's playscheme the cheeky kids would sometimes call me names. Pesky beggers.
By the way, for what it's worth, I think as long as you shave cautiously you're better off than having facial hair. Sure, a beard would cover things up but will it ever allow the acne to go away? Surely they'll be too much potential for excess daily dirt to gather and not enough rejuevenation of the skin cells?
