My 23 year old daughter is in the process of having a few areas done. It's just that -- a process. She has paid for 10 treatments. They are 8-10 weeks apart. She says she has noticed a difference with just the first two sessions. She hardly even has to shave her underarms anymore and is having her bikini area done (and a bit further underneath). One requirement is for her to cover the areas really well with sunscreen, no tanning beds allowed. Hope this info helps. To me, it's expensive, but she says it worth it not to have to shave.
