I finally splashed out and bought one of these. I've used it twice so far - first time just on legs, then 2 weeks later (yesterday) on legs and bikini line. Now I just feel uncomfortable from the regrowth after shaving my bikini line (and am remembering why I've stuck to waxing for the past 20 years), urgh. I know one zapping session isn't enough but how long was it before you saw results? Do more stubborn areas like bikini lines take a bit more time?
