I usually shave the upper lip but would much rather do something like waxing, plucking, etc. to get the hair from the root so the hair removal is longer lasting but I always get acne in the place I've pulled the hair out from if it's my upper lip - I can pull hairs from my eyebrow without it causing pimples but not from my upper lip or chin.
Any ideas/solutions that have worked to prevent such acne for you?
