I would personally never put Nair, or any other chemical delapitory near my face. I understand it works for some people, but I got a rash from it just on my legs, never mind my sensative upper lip. I wax regularily, and I'm not afraid to tell people! haha. It works beautifully, doesn't grow back for about a month and a half, and the hair grows in weaker and more sparsely each time. If you go to a salon, ask them to use hard wax on you. It's a lot less painfull, and it is far less likely you'll have a bad reaction to it.
