Thanks for your question. Yes you can have these procedures together. 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, arms, knees and in your case from the chin and transferring it to create smooth, attractive contours optimized for each person. 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. Best is a Board Certified Plastic Surgeon with specialized expertise in this procedure.
