Hello Renewed11, I appreciate your questions! VASER Liposuction is indeed used effectively in combination with autologous fat transfer to the buttocks (Brazilian Butt Lift (BBL) to achieve a beautifully contoured figure with flawless, well-toned skin. The fat cells harvested are viable with the VASER liposuction as long as the amplitude used by the surgeon is less than 50%. During VASER Liposuction, the surgeon selects the area to be treated and uses the ultrasound-assisted device to emulsify the fat cells, leaving the surrounding nerves, blood vessels and connective tissue unaffected. By only melting fat, the VASER leads to more rapid healing and smoother results. Since the VASER also creates thermal energy, this generated heat causes further fat to dissolve and causes significant skin contracture, as you have read before. Results from clinical studies presented by the American Society of Plastic Surgeons (ASPS) in 2009 demonstrated a 53% improvement in skin contraction relative to the standard liposuction procedures. It’s worth noting that thermal skin contracture is not attainable with traditional liposuction. These clinical studies have also shown significantly less blood loss with the use of the VASER. Specifically, an average reduction in blood loss of 26% compared with traditional liposuction methods. Altogether, these beneficial factors positively impact the procedure final outcome and recovery process. Hope this is helpful! Dr. De La Cruz.
