The Brazilian butt lift is a liposuction and fat injection. The fat is placed in the buttocks this fat is like a skin graft. It has no blood supply. In the best case scenario 65% percent of the fat will live and give a permanent result. The 1st 4 to 5 days the fat cells are the weakest and will die with pressure on the buttocks. I recommend not sitting or laying on the buttocks for the 1st 10 days. If you sit for prolonged periods of time you may not get your best result. Instead of 65% of the cells living maybe only 50% of the cells live.
Traveling soon after the Brazilian butt lift will not give you the best result.
