Hello dear!!Thanks for the question and provided information as well. After a BBL, only about 70% of the transferred fat cells will survive, so it is normal to see a minor reduction in your buttocks. If you have any concerns, I suggest you to follow up close with your plastic surgeon.Good luck :)
I think my graft survival rate is around 70-80%. I take meticulous care to make sure pure fat is being re injected and not a fat slurry that is used in a lot of offices. The grafts also need to be harvested in a non traumatic fashion and processed similarly to maximize their survival. finally aesthetic sense and ability needs to be maximized to really have the body sculpted with all of the liposuction that is being performed
