I've had my underarms done. It took five sessions, and now nothing grows! I love it, as you don't even see the folicle, it's just smooth. Now on my bikini line, and almost have a permanent Brazilian!! I've had four sessions and will probably need another two or so. It just looks so neat and tidy, and will not have to wax anymore which is great!
Let me know if you have any questions about it.
