I had my flanks done after having an abdominoplasty and breast lift done in December. Its been 4 weeks now and I'm very pleased with the result so far, although I know that it is 8 weeks to realize the full results of treatment. It was painless, although the treatment made me feel numb in the area for about two weeks. I'm seeing visible changes. 5 foot 2 inch woman, 105 lbs.
