The thing with laser is that it drastically removes hair, but doesn't eliminate it completely. The bikini region still has small amount of hair, but I don't need to shave for five weeks before I notice any fuzz. Underarms appears to be a longer time. I still do maintenance on the genital region so maybe 16 sessions with a few remaining hairs on the shaft. Underarms was about 5, but I don't have a super dense amount of hair there. Upper thigh I have done 4 and so far I haven't had to shave meaning the laser is doing its job. I haven't noticed any hair reduction with facial hair after one session. I am getting giddy thinking of having a hairless face and not worrying about a shadow. A girl can dream right?
