What is a brazilian butt lift or buttock lipofilling (SMART BBL)?
Also known as the Brazilian butt lift, the Brazilian Butt Lift or BBL is a cosmetic surgery procedure designed to increase the volume of the buttocks, sculpting the entire silhouette to make it sexy and attractive. It involves injecting fat cells taken from other areas. The result is a fuller, shapelier buttock, like that of young Brazilian women who flaunt their beautiful figures in swimsuits.
SMART BBL (Safe Modern and Artistic Brazilian Butt Lift) is an image-guided buttock fat injection technique developed by Paris-based plastic surgeon Dr Delobaux. It enables a safe procedure to be performed, thanks to image control during fat injections into the buttocks.Â
Dr. Alexis Delobaux was the first cosmetic surgeon in Europe to use ultrasound for gluteal lipofilling or Brazilian Butt Lift, and as such is a pioneer in this highly specialized field.
Objectives of a SMART Brazilian Butt Lift
The aim of the Brazilian Butt Lift is to :
- Treat flat buttocks or buttocks lacking curves.
- Treat silhouettes that are straight (H-shaped) and not feminine enough.
- Treat excess love handles or saddlebags.
- Sculpt the figure harmoniously after weight gain or pregnancy.
Buttock lipofilling and brazilian butt lift, for whom?
Lipofilling of the buttocks is aimed at patients aged between 25 and 35 who want more volume, more curves for a fuller, sexier figure.
Patients between the ages of 45 and 55 who, as a result of pregnancy or weight loss, have experienced volume loss and buttock ptosis (sagging of the buttocks), and are seeking above all to harmonize their bodies and regain lost volume.
The advantages of a SMART Brazilian Butt Lift?
Buttock lipofilling improves both body beauty and self-confidence.
A person with a poor sense of self, who finds his or her body "unflattering" and disharmonious, will be metamorphosed by buttock lipofilling.
Dr. Alexis Delobaux has helped many women regain their joy and self-confidence after undergoing buttock lipofilling.
Buttock augmentation is foreign-body-free, so there's no risk of rejection.
What percentage of fat remains after a Brazilian Butt Lift?
Studies on fat transfer show that, on average, 25% of the transferred cells will not survive, which means that 75% of the volume of transferred fat remains for life.
Brazilian Butt Lift procedure

The Brazilian Butt Lift is performed under general or local anesthesia. In the latter case, a single area of fat is removed and reinjected.
The procedure lasts around 3 hours, with an overnight hospital stay.
- LIPOASPIRATION: In the first phase, all pre-defined fatty areas are slowly and gently suctioned away by liposuction to sculpt the silhouette for a slimmer bust and harmonious, attractive curves.
- PREPARATION: The second phase consists in preparing the fat cells: they are washed with saline solution and purified by decantation. Each jar of fat tissue requires approximately 30 minutes of washing.
- REINJECTION: The third phase involves depositing fat cells in the gluteal muscles and transition zones to create the desired shape and volume. These fat cells are deposited in drop form and at different depths to achieve the best fat cell survival rate.
Before brazilian butt lift surgery
Before a bbl operation, you will be given a quote, an information sheet and informed consent. An incompressible period of 15 days is required to allow you to reflect calmly on your decision. If your decision is positive, you will be asked to take a blood sample and to see the anaesthetist for the obligatory pre-operative visit, which must take place in the month preceding the operation.
Preoperative consultation
Each patient describes the result she would like to achieve for her bust, buttocks and sometimes thighs.
The areas to be liposuctioned and injected are determined, and Doctor Alexis Delobaux explains the preoperative, operative and postoperative stages.
Preoperative examinations
A blood test is required to check blood cells, hemoglobin levels, liver and kidney function, serologies and blood group.
After brazilian butt lift surgery
After a bbl operation, a convalescence period of one week is necessary and sufficient. You will be able to sit on your buttocks, but you should avoid doing so for too long during the first week. You must wear a lipopanty for one month.
The results
The brazilian butt lift is a painless procedure. Scars are virtually non-existent. Any marks left on the skin correspond to the diameter of the cannulas used for fat removal and reinjection. Results are long-lasting and the appearance remains natural.
The final result is judged after about 3 months, the time needed to evaluate the rate of fat cell resorption. A second operation is sometimes necessary to perfect the result.
Price of a Brazilian Butt Lift
The price of the brazilian butt lift is given in consultation and is tailor-made according to the size of the operation. It includes the fees of the surgeon and anesthetist, as well as clinic fees and all post-operative visits for one year.
