The Brazilian Butt Lift (BBL) is one of the most in-demand aesthetic surgery procedures of recent years. In this article I explain, drawing on my experience as a plastic surgeon, what this technique truly involves, who can benefit from it and what results patients can realistically expect.
What is the Brazilian Butt Lift (BBL)?
The Brazilian Butt Lift is an aesthetic surgery procedure that enlarges and reshapes the buttocks by transferring the patient's own fat.
Unlike implants, this technique uses fat harvested from other areas of the body, allowing for a more natural and harmonious result. The procedure simultaneously redefines several zones: fat is removed from areas with excess volume (abdomen, flanks, back) and transferred to the gluteal region, creating a more aesthetically balanced body contour overall.
What does the BBL procedure involve?
The procedure is carried out in three distinct phases:
- Fat extraction via liposuction from the donor areas
- Fat processing to select the most viable adipose cells
- Injection into the gluteal region to add volume and shape in a controlled manner
This approach not only improves the appearance of the buttocks but also redefines other body areas, producing a more aesthetic and proportioned overall result.
Who is a suitable candidate for a BBL?
Not every patient is an ideal candidate for buttock augmentation with their own fat. The following requirements must be met:
- Good general medical health
- A balanced body mass index
- Sufficient body fat available for transfer
- Healthy lifestyle habits
"It is very important that the patient has reasonable dietary and lifestyle habits in relation to the surgical procedure to be performed."
The average age of patients tends to be around 40, although this varies depending on each individual case.
The main limitation of the BBL
One of the most important aspects to understand is that the outcome depends directly on the amount of fat available in the patient's body.
"It is not always possible to place as much fat as the patient would like, because it depends on how much we are able to harvest."
This means that very slim individuals may not be suitable candidates, as it may not be possible to obtain sufficient volume to achieve the desired result. For this reason, a personalised pre-operative assessment is essential.
How much fat is retained after a BBL?
After surgery, not all of the transferred fat survives. It is important to understand this before the procedure:
| Outcome | Percentage |
|---|---|
| Fat that remains long-term | ~70% |
| Fat that is reabsorbed | ~30% |
For this reason, surgeons typically transfer slightly more volume than the target outcome to compensate for the expected reabsorption.
"We know that over time the buttocks will lose some volume, which is why we tend to slightly overcorrect."
This adjustment helps achieve a more stable and lasting result over time.
What about scarring?
The BBL is a minimally invasive technique in terms of scarring. The key characteristics are:
- Incisions of approximately 4–5 mm
- Closure with minimal sutures
- Marks that become virtually imperceptible after a few months
This makes it an appealing procedure for patients seeking visible change without obvious scarring.
Results and expectations
The final result of a BBL in Barcelona depends on several factors:
- Surgical technique used
- Quality of the transferred fat
- Post-operative recovery process
- Lifestyle following the procedure
The BBL can offer a more natural appearance than other techniques, but it is essential to have realistic expectations and understand the limitations of each individual's anatomy.
The importance of a medical assessment
Before undergoing this procedure, a thorough consultation with a plastic surgery specialist is essential.
"I always recommend a proper consultation and making sure all doubts are fully addressed."
Good planning is key to ensuring the safety of the procedure and achieving satisfying long-term results.
Frequently asked questions about the BBL
How long do BBL results last?
Results are long-lasting as long as body weight remains stable. Some fat is reabsorbed during the first few months after surgery. Approximately 70% of the transferred fat remains permanently.
Can you choose the exact volume?
Not entirely, because the result depends on the amount of fat available in the patient's body and how much can be safely transferred.
Is the recovery painful?
There may be moderate discomfort during the first few days, but it is generally well managed with prescribed pain relief and diminishes progressively over time.
Are scars visible?
Scars are typically not visible, as the incisions are very small (4–5 mm) and become virtually imperceptible over time.
Is BBL better than buttock implants?
It depends on the individual case. The BBL offers a more natural result because it uses the patient's own fat rather than artificial materials, but it requires sufficient body fat to transfer.
