BBL surgery results should appear smooth—i.e., the skin surface must show uniformity and there should be a smooth transition between the buttocks and the “adjacent areas” such as the posterior thigh, hips, flanks, and lower back.
BBL, which is an acronym for Brazilian buttock lift, is basically a combination of two procedures: liposuction and fat transfer/injection.
Liposuction is the process of removing the “unwanted” fat, which is then re-used to augment and reshape the buttocks and hips to achieve a more feminine figure.
Fat injection, meanwhile, is the process in which the buttocks and hips are reshaped in a way that they look natural and proportionate to the patient’s underlying anatomy. The final results should also reflect the individual’s cosmetic goals and expectations, which she must be able to describe in details during the preoperative consultation.
Inland Empire plastic surgery expert Dr. Tarick Smiley, who performs over a hundred BBL surgeries every year, says that fat transfer is a meticulous process. Instead of dumping the fats all out once, the use of microdroplet injection technique is critical to achieve smooth results and high survival rate of fat grafts.
Any amount that survives after a few months of fat injection is expected to last a lifetime, he says in one of his recent Snapchat videos.
Dr. Smiley warns that incorrect fat injection and over-filling the buttocks can lead to a gamut of aesthetic-related problems such as cellulites, dents, and sagging appearance.
Cellulites and other skin surface irregularities are generally caused by “disturbing” the fascia system, which resembles a cluster of threads connecting the muscle into the skin.
When too much fat volume has been injected into the buttocks, the extra weight causes the fascia to weaken and the butt cheek to sag. This “problem” can be further aggravated by aging and large weight fluctuations.
To avoid skin irregularities and sagging appearance, Dr. Smiley says he never injects “fat volume that goes beyond the capacity of the patient’s fascia system and other relevant anatomies.”
“The key to achieve natural, proportionate BBL surgery results is to respect and acknowledge the anatomical limits. This core principle has also helped me avoid most known complications,” he says.
To further avoid “unnecessary weight” that could make the buttocks susceptible to sagging, Dr. Smiley says he avoids or at least minimizes fat injection into the lower aspect of the butt cheek, focusing more on the upper half portion and the lateral side (hips) instead.
