Yes, it works. It worked best on my legs, less well on my armpits and tummy. The first picture is 1 week into treatments, 1 day after shaving, and the 2nd picture is 6 weeks into treatments, about 4 days after shaving. I started on setting 2 and worked my way up to level 6 over about 6 weeks – 2-3 times per week. First of all, cancel all of your plans. This thing takes hours. That's why I'm taking a break after 6 weeks, I'll go back and do another 6 weeks after summer to get even better results (you cannot use this thing while you're regularly exposing your skin to sunlight). Also, I noticed a tiny bit of discoloration that was definitely not there before – little white spots on my legs that I'm hoping will go away? Definitely make sure you feel comfortable using this device. And I highly recommend wearing eye protection.
