I lost about 70 pounds 10 yrs. ago. I have kept it off due to changes in all my bad habits. Although my body isn't considered saggy it isn't as tight as someone who didn't lose weight at such a high amount. I am in the process of having a bbl with the greatest doctor in bal harbor , Miami dr. Salzhaur. Most of my "saggy skin " is in my torso. Will the Brazilian butt lift help in tightening this area seeing that fat is being added?
