BBL refers to Brazilian Butt Lift, a cosmetic surgery designed to reshape and enhance the buttocks using fat taken from other areas of the body.
This guide explains the basics of BBL, how it works, what to expect before and after the surgery, and why clinics in Miami, such as Smart Plastic Surgery, attract so many patients from across the country and abroad.
What does BBL stand for?
BBL stands for Brazilian butt lift, a buttock augmentation procedure that uses the patient’s own fat instead of implants.
The name reflects the technique’s roots in Brazil, where plastic surgeons helped popularize fat-based gluteal contouring before it spread to the United States.
In medical literature, you will see the same procedure described by more technical names:
- Gluteal fat grafting
- Buttock augmentation with fat grafting
- Autologous fat transfer to the buttocks
- Safe subcutaneous buttock augmentation (SSBA)
Is a BBL actually a lift?
No. Despite the name, Cleveland Clinic notes that a BBL adds volume and improves shape but does not correct sagging or excess skin. Patients with significant skin laxity may need a traditional buttock lift, which removes skin, instead of or in addition to fat transfer.
How a Brazilian butt lift works
A BBL is performed under anesthesia and follows three main stages:
- Liposuction: The surgeon makes small incisions and uses a thin cannula to remove fat from donor areas such as the abdomen, flanks, lower back, or thighs. This step also sculpts those areas.
- Fat processing: The harvested fat is purified to separate viable fat cells from fluid and damaged tissue.
- Fat transfer: The surgeon injects the purified fat through a few small incisions into the layer just beneath the skin of the buttocks, shaping volume and projection according to the surgical plan.
The table below gives a general sense of how the surgery unfolds:
| Stage | What happens | Typical time |
| Liposuction | Fat removed from selected donor areas | 1 to 2 hours |
| Fat processing | Fat purified for transfer | 30 to 60 minutes |
| Fat transfer | Fat placed in the subcutaneous layer of the buttocks | About 1 hour |
Most procedures take roughly three to four hours in total, depending on the number of donor areas and the amount of fat transferred.
According to Cleveland Clinic, surgeons usually need about 300 to 500 cc of fat per side to create a noticeable change.
Different surgical approaches produce different looks, which we cover in our guide to the different types of Brazilian butt lift.
Why the BBL became so popular
The BBL ranks among the most requested body contouring procedures in the United States, and demand keeps rising. WebMD, citing American Society of Plastic Surgeons (ASPS) data, reports that U.S. surgeons performed BBLs on 36,792 women and 628 men in 2024. That is a significant increase from the 14,705 procedures ASPS recorded in 2015.
Several factors drive this growth. Social media and celebrity culture made the curvier silhouette mainstream, and the procedure appeals to patients who want a change that exercise alone cannot deliver, since buttock shape is largely determined by genetics. The dual benefit of slimming one area while enhancing another also sets the BBL apart from implants.
Geography plays a role too. WebMD notes that nearly half of U.S. BBLs take place in South Florida, which is one reason the state has developed the most detailed safety regulations in the country.
Who is a good candidate for a BBL?
The right candidate is someone whose goals match what fat transfer can realistically achieve.
You may be a good candidate if you:
- Are at least 18 and in good general health
- Have enough excess fat in donor areas to transfer
- Maintain a stable weight
- Do not smoke, or can stop for several weeks before and after surgery as your surgeon directs
- Have realistic expectations about size and shape
- Can avoid sitting directly on your buttocks for at least two weeks
Body mass index matters, but it is not the only factor. Many surgeons prefer a BMI roughly between 20 and 30, since very low body fat limits donor supply and higher body fat can make changes harder to see. Learn more in our guide to the ideal BMI for plastic surgery. Slim patients often still qualify through a Skinny BBL, which harvests fat from several areas to build shape rather than maximum volume.
Uncontrolled diabetes, heart conditions, or bleeding disorders may rule out surgery. Your surgeon will review your full medical history, medications, and supplements during consultation.
What BBL recovery looks like
Recovery follows a predictable timeline, and following your surgeon’s instructions directly affects how much transferred fat survives.
The table below outlines what most patients experience:
| Phase | What to expect |
| Weeks 1 to 2 | Soreness, swelling, and bruising, especially in liposuction areas. No sitting on the buttocks; sleep on your stomach or side. Wear your compression garment and take short walks. |
| Weeks 2 to 8 | Sit only on a BBL pillow, for short periods. Many people return to desk work around days 10 to 14, often using a standing desk. Light activity resumes after about one month. |
| Months 2 to 3 | Most normal activities, including exercise, resume after surgeon clearance. |
| Months 3 to 6 | Swelling resolves and the transferred fat settles into its final shape. |
Most patients describe the first days as intense soreness rather than sharp pain.
For a day-by-day breakdown, read our guide on how painful a BBL is, and review our post-operative care instructions before surgery.
How long do BBL results last?
BBL results are long-lasting, but not every transferred fat cell survives. According to WebMD, the body typically absorbs about 20% to 40% of the injected fat during healing. The fat that establishes a blood supply in the first months behaves like the rest of your body fat from then on.
That means your weight shapes your results over time. Significant weight gain can enlarge the buttocks along with other areas, while major weight loss can reduce volume.
Keeping a stable weight is the most reliable way to preserve your outcome. Patients who want more volume later may consider a second-round BBL once the first result has fully settled.
How much does a BBL cost?
A BBL at Smart Plastic Surgery starts at $5,500. Your final price depends on the number of donor areas, the amount of fat transferred, and whether you combine the BBL with other procedures such as a tummy tuck. Every quote is itemized during your consultation.
Because a BBL is cosmetic, health insurance does not cover it. Financing is available through CareCredit, Affirm, and Alphaeon for patients who prefer monthly payments.

BBL vs. butt implants vs. traditional butt lift
These three procedures are often confused, but each solves a different problem.
The table below compares them side by side:
| Brazilian butt lift | Butt implants | Traditional butt lift | |
| What it does | Adds volume and shape with your own fat | Adds volume with a silicone implant | Removes loose skin and lifts the buttocks |
| Adds volume? | Yes | Yes | No |
| Contours other areas? | Yes, through liposuction | No | No |
| Incisions | Small liposuction and injection incisions | Larger incisions for implant placement | Longer incision, usually along the upper buttock |
| Best for | Patients with enough donor fat who want a natural look | Patients with very little fat to transfer | Patients with sagging skin, often after weight loss |
| Specific considerations | Fat absorption; requires strict subcutaneous technique | Implant shifting, capsular contracture, infection | Visible scar; no volume increase |
Some patients combine approaches. For example, a buttock lift with fat transfer can address both laxity and volume. Your surgeon can explain which buttock enhancement technique fits your anatomy.
Alternatives to a BBL
Fat transfer is not the only path to a rounder shape. Depending on your goals, your surgeon may discuss these options:
- Liposuction alone: Removing fat from the waist, flanks, and lower back can make the buttocks look more prominent without adding volume. See how this compares in Lipo 360 vs. BBL.
- Skinny BBL: A BBL adapted for slim or athletic patients with limited donor fat.
- Injectable biostimulators: Products such as Sculptra can add modest fullness over several sessions without surgery, though results are subtler and temporary.

Frequently asked questions
Transferred fat that survives the first few months becomes a lasting part of your body. Results can last many years, but weight changes and aging will affect your shape over time.
A BBL carries real risks, including fat embolism, but modern standards have lowered them considerably. Choosing a qualified plastic surgeon who injects fat only above the muscle under ultrasound guidance is the most important safety step.
Most surgeons advise no sitting directly on the buttocks for at least two weeks. After that, you will usually sit only on a BBL pillow for short periods for up to about eight weeks.
The incisions measure only a few millimeters and are placed in natural creases or areas covered by underwear when possible. Most fade significantly within a year.
Not completely, but excess fat can be reduced with liposuction and irregularities can often be corrected with revision surgery. Learn more about what to do if your BBL doesn’t turn out as expected.
