I have also had really good results. I have done bikini, underarm, and lower leg. True, I do still have to go in once a year or so for touch-ups, but it is so worth it.
I wouldn't say the bikini area is horribly painful, just a little "ouchy," but my aesthetician ALWAYS uses the numbing cream. I can't imagine doing it without numbing cream (especially in the "back door" area, if you know what I mean!).
I absolutely LOVE the woman who takes care of me. Her name is Traci Rupe and she works at Dr. Stuart Lipton's office in Lewisville. The number is 972-420-0023. She is a fabulous person as well as great as what she does.
