Virtually every one of these replies notes that fat grafting requires living cells to enhance the buttocks; since Smart Lipo kills the fat cells by thermally destroying them via laser energy, this is not the way to go. Even "traditional" liposuction utilizes high negative pressures that can literally "boil" fat cells at room temperature (because of the very low pressures), destroying many of the potential living cells for grafting. When these modalities are used to harvest the fat for transfer, mostly dead cells and lipid (fat) are injected, ultimately removed by your body's scavenger blood cells, and little or no long-term improvement.
Fat grafting requires low-suction harvest techniques, careful placement to surround the transferred fat globules with living tissue, and reduced activity while healing the grafts. The Brazilian Butt Lift is a time-consuming and precision procedure that is not for every patient, and not for performance by every surgeon.
