Electrolysis

[Ponyup]

No idea if I spelled that right. Anyone done this before? My hairstylist knows of a girl that does it that she went to school with. Says she's nice & that she appreciticed under a woman that had done it for 40years (i didn't know it had been around that long). I figure that if there were any long term side effects they would be evident by now. How large of an area can be done? I would want my bikini area done & my armpits & maybe my knees. Any thoughts would be good, I'm in the research stage.
