A BBL is not implants. A Brazilian butt lift (BBL) uses your own body fat to add volume to your buttocks, while butt implants are solid silicone devices surgically placed inside the muscle. The two procedures are often confused because they achieve a similar goal, but they work in completely different ways, carry different risks, and suit different body types.
How a BBL Works
A BBL is a fat transfer procedure. Your surgeon first performs liposuction on areas like your stomach, thighs, or flanks to harvest fat. That fat is purified, then injected through small incisions into the buttocks. Most of the fat goes into the upper region for a lifted, rounded shape, with less injected into the middle. The fat is placed into the layer just beneath the skin rather than deep into the muscle.
A typical BBL requires roughly 300 to 500 ccs (about 1⅓ to 2¼ cups) of fat per side. Not all of that fat survives the transfer. A portion of injected fat cells will be reabsorbed by the body over the first few months, which is why surgeons often inject more than the final desired volume. The fat that does survive becomes a permanent part of your body, though significant weight loss can reduce results over time.
How Butt Implants Work
Butt implants are solid silicone shapes that a surgeon places inside or beneath the gluteal muscle through an incision, typically hidden in the crease between the buttocks. Unlike breast implants, which are filled with liquid silicone or saline, gluteal implants are semi-solid, so they won’t rupture or leak.
The most common placement is submuscular, meaning the implant sits underneath the gluteal muscle. This positioning reduces the risk of the implant shifting or becoming visible under the skin. Because implants provide a fixed, structural volume, the results are more predictable than fat transfer, where some fat inevitably gets reabsorbed.
Who Is a Better Candidate for Each
The biggest factor determining which procedure suits you is your body composition. A BBL requires enough donor fat to harvest a meaningful amount through liposuction. If you’re lean or have a naturally thin frame without much excess fat, there simply isn’t enough raw material for a BBL to produce noticeable results. Implants exist largely for this reason: they deliver reliable projection regardless of body fat percentage.
A BBL tends to look and feel more natural because the added volume is your own tissue. It also has the bonus of slimming the areas where fat was harvested, giving a more contoured overall silhouette. For people who have enough donor fat and want subtle to moderate enhancement, a BBL is generally the more popular choice. Implants are better suited for patients who want significant, consistent size increase or who simply don’t have fat to spare.
Some surgeons now offer a composite approach that uses both: a small implant for core projection, with fat grafted over it for a natural feel. In these procedures, the average implant volume is around 300 ccs with about 380 ccs of fat layered on top.
Recovery Differences
BBL recovery centers on protecting the newly transferred fat cells. You’ll need to avoid sitting directly on your buttocks for the first 10 days entirely. After that, you can sit using a special BBL pillow that shifts your weight to your thighs. Most surgeons clear patients to sit normally around six weeks after surgery, though some allow it as early as three to four weeks.
Implant recovery involves different restrictions. Because the implant is placed inside the muscle, discomfort tends to be more intense in the first week or two compared to a BBL. Sitting limitations still apply, but the primary concern is avoiding activities that strain the gluteal muscle while the surgical pocket heals. Full recovery from implants typically takes longer, and the initial soreness can be significant since the muscle has been surgically separated to create space for the device.
Safety and Risks
Both procedures carry standard surgical risks like infection and poor wound healing, but each has unique concerns. The most serious BBL risk is pulmonary fat embolism, which occurs when injected fat enters a damaged vein in the gluteal muscle and travels to the lungs. This complication is rare but can be fatal. In South Florida alone, 25 deaths from this cause were recorded between 2010 and 2022. The risk is highest when fat is injected deep into the muscle rather than into the tissue layer just beneath the skin, which is why professional guidelines now emphasize subcutaneous-only injection.
Implant risks are different. The most common complications include implant displacement (shifting out of position), infection around the implant pocket, and fluid collection. Because no fat is being injected into the gluteal muscle, there is no risk of fat embolism. However, implants can sometimes need to be replaced or removed if complications arise, and revision surgery carries its own risks.
Cost Comparison
The two procedures cost roughly the same. The average surgeon’s fee for a BBL is $7,264, while butt implants average $7,964, according to the American Society of Plastic Surgeons. These figures cover only the surgeon’s fee. When you add anesthesia, facility costs, post-surgery compression garments, special pillows, prescriptions, and follow-up visits, the total typically runs higher. A BBL can sometimes cost more overall if extensive liposuction is involved, since the fat harvesting adds operating time and complexity.
