never, ever get waxed for facial hair. is a waste of time as it either misses hair, or as you have described takes a layer of your face off. i have also had problems with acne and taken roaccutane in the past and get my facial hair threaded instead. this is an indian method of hair removal where the beautician uses two pieces of cotton intertwined to pluck out smaller sections of you r hair (so is also less painful than waxing) and has been very successful for me.
it costs about £6-7 a go for brows and you can get other areas done as well - needs doing every three weeks with plucking stargglers inbetween keeping you tidy. ask around or look for a reputable salon which does this. waxing is broccoli and i would never, ever entertain the idea for any part of my body again. in the mean time, use something like bepanthen nappy rash cream to calm your face down and promote healing, but you will just have to hide - if you put stuff on it to disguise it, you may well end up infecting your skin. good luck, sweetie x
