If you are looking at a small amount of liposuction and injecting that fat into the buttock, that can be 2-3 hours. If you are looking for body contouring with liposuction and removal of all the fat, preparing that fat and injecting that fat in a three dimentional careful manner for optimal take of the graft then it will take 4+ hours
The time it takes me to perform a Brazilian Butt lift varies from 2-5 hours. The variation in time is generally related to the fat harvesting (liposuction) portion of the procedure. I have to liposuction several different areas in slim patients which can take more time. Liposuction is more difficult to perform in patients who have had previous surgery due to the formation of scar tissue. Adding other procedures to the BBL would, of course, increase the procedure time as well.
