Brazilian Butt Lift
Body area: body
Overview
A Brazilian Butt Lift uses fat transfer — harvesting fat via liposuction from donor areas and injecting it into the buttocks — to enhance buttock size, shape, and projection. It is one of the most popular but also most scrutinized cosmetic procedures due to historically elevated safety concerns.
Who is it for?
Patients who desire fuller, more projected, and more shapely buttocks and have adequate donor fat for liposuction. Candidates should be at a stable weight.
Technique overview
Fat is harvested via liposuction from areas such as the abdomen, flanks, and thighs. The fat is processed and then carefully injected into the buttocks at the subcutaneous level. Current safety guidelines emphasize injecting fat above (superficial to) the gluteal muscle fascia to avoid intramuscular injection, which has been associated with fat embolism risk.
What this procedure cannot do
Brazilian Butt Lift has historically had the highest mortality rate of any cosmetic procedure, primarily due to fat embolism from intramuscular fat injection. Modern safety guidelines — endorsed by major plastic surgery societies — require fat to be injected only above (superficial to) the gluteal muscle fascia, never into or below the muscle. Choosing a surgeon who follows current safety protocols is the single most important decision for this procedure. Beyond safety: fat survival is variable (50–70% retention typical), so size and shape outcomes cannot be precisely predicted; patients with limited donor fat may not achieve significant projection; and BBL cannot lift severely sagging buttocks (which requires a buttock lift with skin removal).
Scars and incisions
Fat is injected through small (3–5 mm) cannula entry points at the buttocks, hidden in natural creases. Donor sites (typically abdomen, flanks, lower back) have similar small liposuction access incisions. All incisions heal as small flat marks within 6–12 months and are easy to hide. There are no significant skin incisions on the buttocks themselves.
Recovery
Patients must avoid sitting directly on the buttocks for 2 to 3 weeks (special cushions are used). Most patients return to work within 2 weeks. Compression garments worn at donor sites for 4 to 6 weeks. Fat reabsorption occurs over 3 to 6 months.
Longevity of results
Fat that survives the first 6 months is essentially permanent, behaving like native buttock fat. Long-term volume responds to weight changes — significant weight gain expands the buttocks; significant weight loss shrinks them. Buttock skin and shape continue to age and respond to gravity over time, so some patients elect a touch-up session years later for refinement.

How to choose a surgeon
BBL safety depends critically on technique. Choose a surgeon board-certified by the ABPS who explicitly follows current safety guidelines (subcutaneous-only injection, ultrasound or visual confirmation of plane), uses a single-hole cannula or other technique consistent with safety recommendations, performs BBL in an accredited facility with board-certified anesthesia, and documents safe operative time. Ask directly: 'Do you inject only above the muscle fascia, never below?' Be cautious of providers who travel to perform BBL, work in non-accredited facilities, advertise unrealistic before/after photos, or charge unusually low prices — BBL has historically been a high-volume, low-cost target for unsafe practitioners.
Frequently asked questions
Is BBL safe?
When performed by a properly trained surgeon following current safety guidelines (subcutaneous-only fat injection, accredited facility, board-certified anesthesia), modern BBL safety has improved substantially compared to historical rates. The complication that drove the high mortality — intramuscular fat injection causing fat embolism — is preventable with correct technique. The single most important decision is provider selection.
How much projection can I get?
Achievable projection depends on your starting anatomy, available donor fat, and your surgeon's technique. Patients with more donor fat typically achieve more dramatic results; very lean patients may have limited options. Final results emerge at 6 months once swelling and fat absorption are complete; about 50–70% of injected fat typically survives.
How long do I have to avoid sitting?
Most surgeons recommend avoiding direct sitting on the buttocks for 2–3 weeks (using a special cushion that distributes pressure to the thighs), then gradual return to normal sitting over the following weeks. The rationale is to protect blood supply to the new fat during the most critical survival period. Specific protocols vary by surgeon.
What if I gain weight after BBL?
Surviving fat behaves like native buttock fat — it expands with weight gain and shrinks with weight loss, sometimes disproportionately depending on your individual fat distribution patterns. Significant weight changes after BBL can alter the shape meaningfully. Stable weight is best for long-term results.
