Most Helpful Girl
I use it for my upper lip because waxing is a pain (and you have to wait for it to grow out a certain length before you can wax again) and shaving is out of the question.
I used to use it on my legs but it's just too much hassle to get it all over the legs and then wipe clean off. I tried it on my under arms once and had to hold my hands over my heads for a good ten minutes. Never tried that again.
I know a lot of girls don't use it because they have sensitive skin and chemical hair removers can really wreck havoc on sensitive skin. Personally, I think it's only useful for small areas (i.e. upper lip) but no girl wants to admit to having to deal with hair on her upper lip. Which may be why you've never heard of anyone using it?
