Buttock Augmentation With Fat Transfer (BBL): The Complete Expert Guide

Buttock augmentation with your own fat — the Brazilian Butt Lift (BBL) — reshapes and enlarges the buttocks using fat harvested from other areas of your body. It’s natural, sculpts two areas at once, and, done well, gives lasting results. Here’s the complete expert guide.

What is fat-transfer buttock augmentation?

Fat is harvested by liposuction from donor areas (abdomen, flanks, back or thighs), purified, and re-injected into the buttocks to add volume and improve shape — no implants, using your own tissue.

Advantages of using your own fat (BBL)

• Natural results, minimal rejection: because it’s your own tissue, the body accepts it and the result looks and feels natural.
• Dual benefit: it slims the donor areas (waist, abdomen) while enlarging the buttocks — sculpting the whole silhouette.
• Long-lasting volume: the fat that survives becomes permanent, for a durable result with a stable weight.

The ideal candidate

• Enough donor fat in the abdomen, flanks, back or thighs.
• Good general health, at a stable weight, and a non-smoker (or able to stop).
• Realistic expectations about shape and volume.
• A clear cosmetic goal for buttock shape and body proportion.

How it’s done

Under anaesthesia, fat is harvested by liposuction (often VASER for precision), purified, and injected at multiple depths and points across the buttocks to build a smooth, even, natural shape — while the donor areas are contoured at the same time.

Recovery

• Avoid sitting directly on the buttocks for the first weeks (use a special cushion, or sit on the thighs).
• Sleep on your front or side, not on your back.
• Wear the compression garment as directed.
• Walk lightly to boost circulation; avoid strenuous activity for several weeks.
• Eat well and stay hydrated to support fat survival.

Results and safety

Some of the injected fat is naturally reabsorbed in the first months; what remains is permanent, with the final result settling over about 3–6 months. Safety depends heavily on surgeon skill and correct injection technique — which is why an experienced body-contouring surgeon matters most.
