When planning a Brazilian butt lift, patients can look forward to a double benefit: reducing areas of unwanted fat while gaining a perkier, rounded posterior. Each procedure must be planned according to the individual needs of patients, harvesting fat from target areas of the torso, thighs or knees and transferring it to create smooth, attractive contours optimized for each person.The amount of fat transferred depends on the quantity available and the extent of buttock augmentation each patient desires. Sufficient body fat for a buttock augmentation is very patient-specific, depending on an individual’s body shape and proportions as well as their expectations. I have never taken fat from the breast for BBL and think it is a bad idea in general. Best donor sites are usually from the hips, thighs and lower back, which could then be transferred to your buttocks. This sculpting of the body through liposuction and fat grafting can result in a dramatic enhancement of feminine curves.Buttock augmentation with fat grafting is one of our most popular procedures in Colombia, and from experience we can tell you that some patients do very well with 300 cc of fat per side while others can need 600 cc or more. That said, you definitely have to choose your surgeon correctly and make sure that he/she has the training and experience to meet your goals with absolute safety.
