What is buttock fat grafting?

A rear lower-body drawing highlights the buttock area considered for fat transfer.

Buttock fat grafting takes fat from another body area with liposuction, prepares it and transfers it to the buttocks. It is also called gluteal fat grafting or a Brazilian butt lift, often shortened to BBL.

Despite the name, it mainly adds volume and changes contour. It does not remove a large fold of loose skin, build muscle or provide overall weight loss.

Fat transfer and a skin lift do different things.

Selected buttock areas are highlighted for volume planning.

Fat transfer adds volume

Your own fat can add fullness in selected areas. The available donor fat, skin and anatomy limit the change that can be planned.

Front and back views show a skin-removal plan around the waist.

A lift removes loose skin

A buttock or lower-body lift addresses excess skin and tissue position. It leaves a different scar and may be more relevant after major weight loss.

Explore body lifts

A suction cannula targets fat beneath the skin.

Liposuction reduces a fat pocket

Liposuction reshapes the donor area by removing selected fat. On its own it does not add buttock volume.

Explore liposuction

Buttock implants and synthetic filler injections are different procedures. Their materials and risks should not be confused with using your own fat.

Where does the fat come from?

Example donor areas are marked on the abdomen, waist and thighs.

01
Selected body areas
The abdomen, waist or thighs may provide donor fat. The surgeon assesses each area, its skin and the contour that would remain after collection.
02
Enough suitable tissue
A very lean person may not have enough fat for the desired change. Do not gain weight or pursue a larger transfer target without a medical discussion.
03
A realistic volume plan
Not every collected fat cell is used or survives. There is no universal volume that suits everyone, and adding more is not automatically better.

Placement above the muscle matters.

A cannula tip and transferred fat remain in the layer above the fascia covering the muscle, with ultrasound used to observe the area.

Specialist safety guidance supports placing fat only in the tissue beneath the skin and above the fascia that covers the buttock muscles. Real-time ultrasound helps the surgeon monitor the cannula tip during placement.

Fat entering large blood vessels can travel to the lungs and cause a fatal fat embolism. This is a particularly serious risk of gluteal fat grafting. Ultrasound and appropriate technique reduce risk but do not make the operation risk-free.

01
Ask about the actual surgical setup
Confirm who will perform the fat transfer, their training, use of real-time ultrasound, the operating facility and who manages complications and follow-up. These details should be clear before consent.

Is fat grafting suitable for your goals?

A checklist represents an individual assessment of the concern, method and recovery.

01
Volume is the main concern
Explain the change you want. Significant loose skin may need a lift, and an extreme size target may not be appropriate for your anatomy.
02
Your health supports surgery
Review your medical history, medicines, nicotine use, weight stability and blood-clot risks. The whole operation includes the liposuction as well as the fat transfer.
03
You can plan for aftercare
Pressure restrictions affect sitting, sleep, work and travel. Arrange practical help and access to the surgical team before choosing a date.

OUR PROCEDURE

Before, during and after fat grafting.

STEP 01

Assess and prepare

Agree the areas and limits
The surgeon examines the donor and buttock areas, reviews your health and discusses the possible change and risks. Confirm the anaesthetic, facility, ultrasound and aftercare.
Prepare for recovery
Follow individual instructions for medicines, nicotine, eating and drinking. Arrange transport, help at home and a plan for sitting and sleeping.

Potential donor areas are shown for an individual assessment.

STEP 02

Collect, prepare and transfer

Collect and prepare fat
Liposuction removes fat from the agreed areas through small openings. The collected tissue is prepared for transfer.
Place fat in the planned layer
Fat is placed in the subcutaneous layer above the muscle covering, with real-time ultrasound used to observe placement. The access points are closed or dressed as appropriate.

A schematic collection container shows the patient’s fat being prepared for transfer.

STEP 03

Protect the areas while healing

Monitoring and wound care
The team monitors you before discharge and explains dressings, medicines and any garment or drain care. Keep the contact details for problems.
Pressure and movement guidance
Follow the surgeon’s instructions for sitting, sleep positions and gentle movement. Attend the planned reviews before increasing activity.

Plan for sitting, sleeping and daily life.

A planning checklist represents arranging support during recovery.

01
Limit pressure as instructed
Prolonged sitting can affect newly transferred fat. You will need a specific plan for sitting and sleep, including how and when to use any support cushion.
02
Care for the donor areas too
Liposuction sites can be bruised, swollen and sore. Follow the garment and wound instructions for each area; do not improvise tight compression over the grafts.
03
Return to work and exercise gradually
Recovery takes weeks and depends on the extent of the operation. Desk work, driving, travel and exercise each need a plan. Ask before booking long journeys or returning to strenuous activity.

Understand the possible complications.

Fat embolism and serious illness

Fat entering blood vessels can block blood flow in the lungs and can be fatal. Blood clots, anaesthetic complications and heart or lung problems are also serious surgical risks.

Healing problems

Bleeding, infection, fluid collections, poor wound healing, skin damage and scars can occur in the donor or treated areas.

Unevenness or loss of volume

Some transferred fat may not survive. Fat necrosis, lumps, asymmetry, contour irregularities or a smaller change than expected can occur. Further surgery may be needed.

Allow time for the volume to settle.

Early swelling is not the final result. Some fat is absorbed, and the contour changes as healing progresses over the following months. A precise retained volume or shape cannot be guaranteed.

Surviving fat responds to weight change. A stable weight supports the result, but ageing and skin changes continue. Any further treatment should wait for reassessment of healing and your goals.
