I am 25, fit & healthy, 170cm tall & 62kg. I have stubborn pouches of fat on my outer thighs that stick out. I had ultrashape 3 sessions on both thighs. I experienced a hot pricking sensation during the treatment (similar to laser hair removal) but it was quite bearable and I had no side effects at all afterwards - I went straight back to work.
My treatments were 1 month apart and after the 3 rd one I had seen no results whatsoever despite losing 2kg over the period. The nurse told me it could take 3 months to see results, so I waited hopefully but it is now 1 year later and my measurements have not changed at all. Very disappointed. I guess it works for some people but not for me so I would not recommend it to anyone with my body type.
