A very good "normal" example of body modification, just not as permanent. And there are degrees to that as well...I've seen lipstick colors that just enhance the lip color and give a sheen that I don't think twice about, but even my favorite celebrities look off putting to me when made up "heavily". I'm a bit on OP's side as far as preferring the natural look, although minor studs or a small tattoo somewhere don't catch my attention in a negative way, if I even notice.
