Hi there- There are two very important points for you to understand... First of all, I would not usually recommend using fat harvested by laser, VASER, waterjet, or power-assisted liposuction for grafting in a Brazilian Butt Lift. These techniques are too traumatic to the fat and might compromise the outcome you desire. The second and possibly more important point to make, however, is that I would not agree that these techniques are "less-invasive". The marketing professionals at work for the companies that make these devices would love for you (and the doctors they are trying to sell these machines to) to believe that they offer less invasive options for improvement in your body contour, but the truth is that liposuction is liposuction. Whether you precede the contouring with application of laser energy or ultrasound energy, the fundamental procedure of removing the fat is still performed, and I would argue that the use of the laser energy makes these techniques a bit MORE invasive than carefully performed tumescent liposuction. If you desire a larger, rounder butt, the Brazilian Butt Lift technique is a great option- find a surgeon certified by The American Board of Plastic Surgery with a lot of experience doing these procedures (ask to see photos and maybe even speak to a few patients who have had the operation). There are many providers without plastic surgery residency training doing liposuction in many forms- be careful.. the years of training a board certified plastic surgeon receives in liposuction cannot be replaced by the few days or weeks these alternative providers receive. Here's to you and your new, round butt!
