These two terms are basically just marketing terms. Focus on choosing on finding an experienced surgeon with excellent results demonstrated on their website. Consider several consultations, so that you can hear multiple opinions on how best to obtain your goals.
Thank you for your question. Micro body contouring is lipo as well. It implies that the surgeon uses very small liposuction cannulas (3mm or less). This is what everybody uses, unless you are doing large amount of fat debuliking with a 4mm or 4.6mm cannula. It is more about the surgeon's ability and artistry than the cannula size. See a board certified plastic surgeon for an in person consultation/evaluation. Look at their in office photos and web sites to see if the results posted are close to your expectations. Good luck.
