Some moles (forget what they are called) are attached to nerve bundles or blood supply. They can't be safely removed without risk of facial paralysis or potential issues with loss of blood supply to surrounding tissue. I only mention it because not everything that looks mole-ish is the common mole. Aside from that, while SicSemperTyrannis' reply is a overly harsh, IMHO, he's also not wrong. Humans are flawed. White teeth is not natural for most people. Some people have bulbous noses or big ears. While we're suppose to be largely symmetrical, most of us are not. It's rather common for women (most in fact) to have one breast larger than the other. So on and so on. We should learn to accept our flaws and flaws in others rather than figure out ways to dislike ourselves and fund Jews with cosmetic surgeries for things which are perfectly normal. Which I believe is his more measured point.
