I had 12 zerona laser treatments on my stomach and thighs and was able to lose about 9 inches total off both places. I also lost 14 lbs - from 132 to 118. I'm only 5'3" - so this made a big difference.
I was VERY skeptical - but it did work. I changed my diet a little and stepped up my evening walks, but did not do anything drastic. My doctor was actually in the trials for the machine - so I think she understands how it works better than most.
I've posted my before and after photos that we took in her office. Fair warning - I did a spray tan for my afters.
