Buttock implants can't help shape the lower part of your buttocks, but fat injections can. Some refer to fat grafting to the buttocks as Brazilian butt lift.
Fat grafting is becoming popular as to other body parts such as the breasts and face as well. The reason for this uptick is that plastic surgeons are honing their craft, and research is emphasizing many of the rejuvenating properties found in fat.
Brazilian Butt Lift: Risks and Challenges
Despite the increase in research on fat grafting to the butt, many questions remain. For example, there is no exact science behind how much fat to harvest or inject. The fat that is injected must develop its own blood supply to survive — and, on average, just half of it does. This means that 50 percent of the injected fat dissolves. To compensate, some plastic surgeons will over-inject. They don't always get it right, and repeat treatments are often needed.
Additionally, fat grafting to the buttocks and elsewhere is considered to be extremely technician dependent.
Understanding the Brazilian Butt Lift
Brazilian butt lifts and other fat grafting procedures use liposuction to extract fat from your thighs, abdomen or flank. This excess fat is then purified and re-injected into your backside. There are many techniques that can be used for processing and re-injecting the fat.
Fat injections can be done in conjunction with butt lifts. They should not, however, be done at the same time as butt augmentation with implants because this increases the risk of infection, implant extrusion and poor cosmetic results.
Risks associated with the Brazilian butt lift include asymmetry, infection, scarring and cosmetic dissatisfaction. The last of these is especially pronounced in light of the uncertainties surrounding this procedure. There are also risks associated with the liposuction used to vacuum out the fat for grafting.
