Thanks. I guess that makes sense. I tried regular Nair on my legs once and it didn't do anything, either, so I guess I wouldn't try it on my face.
I do end up shaving off what Nair doesn't get on my upper lip, but I feel this makes it come back in more coarse. Or, at least, the ends are straight instead of fine and whispy, and it feels "prickly" which really gets on my nerves!
