I’ve noticed that every time I’ve tried to wax, I get a sudden few zits in that area.  It can be explained by hair suddenly being pulled out of the follicles, and frankly oil buildup starts in the hair follicles in general.  But it can also be explained by the fact that many waxes are wax, they are heavy, they clog the pores to some degree if you haven’t noticed, and though they’re supposed to come off in general, often times they don’t, even though they are hard among other things.  This is what I figure, and unless you really wash it off well, I haven’t really figured that one out yet, obviously, but if you wash it off well it shouldn’t be a problem.  I think with me it somehow gets into the pores at a deeper level, and frankly it clogs them that way, maybe I heat it up too much or something.  Plus the whole idea of burning the skin with that hot wax, the redness just doesn’t go away as fast as you would actually think.  So all in all, there is also the fact that it pulls off a thin layer of skin, also not appealing.  Waxing in general is not as great as I sometimes thought, especially in the acne factor, and I would look further into it before doing it if I were you in general terms.
