The one honest thing
The single most important question is whether fat goes only under the skin, never deep into the muscle. That one answer is about your life.
Quick answer

How do I choose safely?

A BBL has the highest death rate of any cosmetic surgery, almost always from fat entering the large veins of the buttock. So the questions that matter most are whether fat is placed only in the subcutaneous layer and never into the muscle, whether ultrasound guidance is used, and who is operating. Confirm a board certified surgeon, an accredited facility, and safe technique, all in writing.

This is general guidance, reviewed July 2025, to help you assess any clinic you are matched with. It is not medical advice and not a substitute for a qualified doctor.

How to choose and what to ask

Seven questions before you pay.

For a BBL these are not box ticking, they are safety. A clinic that cannot answer the first two clearly is not one to trust with this procedure. We do not name clinics, so use these to judge any you are sent.

1
Is fat placed only in the subcutaneous layer, never into the muscle?
This is the question that protects your life. Injecting fat deep into the gluteal muscle is what causes fatal fat embolism. Safety advisories recommend placing fat only above the muscle, in the subcutaneous space. A clear, confident answer here matters more than anything else.
2
Do you use ultrasound guidance during fat transfer?
Real time ultrasound helps the surgeon keep the cannula above the muscle and is increasingly recommended to lower the risk. Ask whether it is used for every case.
3
Who performs the surgery, and what are their credentials?
Ask for the named surgeon, their specialist plastic surgery qualifications, and membership of a recognised body. A BBL should be done by an experienced, board certified surgeon, never a technician.
4
Is the facility accredited, and who gives the anaesthesia?
Ask where the surgery happens, what accreditation the facility holds, who provides the anaesthesia, and how you are monitored during and after, since the highest risk window is the first hours.
5
How many BBLs does the surgeon do in a day?
Operating quickly and at high volume is linked to higher risk. A surgeon doing many cases a day cannot give each the care and time a safe BBL needs. Be wary of conveyor belt clinics.
6
Can I have a written plan with realistic expectations?
A proper consultation checks you have enough fat to harvest, sets out the plan, and gives an honest view of the result, including that some transferred fat does not survive. It should not promise a fixed size.
7
What is the aftercare, and what happens if there is a complication?
Ask about sitting restrictions, garments, reviews, and how follow up works once you are home. Agree how complications and revisions are handled, including cost, since travel insurance rarely covers elective surgery.
The warning signs

Red flags to walk away from.

For most procedures a red flag means slow down. For a BBL, several of these together mean walk away.

No clear answer on fat placement

If a clinic cannot or will not confirm that fat is placed only above the muscle, that alone is reason to look elsewhere.

A price far below the market

For a BBL the cheapest offers often come from high volume clinics, the very setting linked to higher risk. Cheap is a warning, not a win.

Pressure to book quickly

Limited time discounts and deposits demanded before a proper assessment are sales tactics, not clinical care.

Promises of a guaranteed size or look

No honest clinic can promise an exact result, since some transferred fat does not survive. Claims that sound too good usually are.

Questions specific to travelling

The part that travel adds.

Distance changes the calculus. The questions above still apply, plus a few that only matter when you fly home after major surgery.

Ask how many days you should stay before flying, since surgery and long flights both raise the risk of blood clots, and a BBL also requires you to avoid sitting normally for a time. Ask how reviews will happen once you are home, whether by video or with a local doctor, and who is responsible if a revision is needed.

Keep copies of your operation notes, including the technique and where the fat was placed, and your aftercare instructions in writing. A local doctor treating a complication will need them, and clinics in another country are not always quick to share records later.

Finally, check the language of your consent and aftercare materials. For a procedure this serious, you should fully understand the risks and the recovery before you sign anything.

Get Matched with a vetted clinic

Now you know what to ask, compare safely.

Send one brief and we route it to vetted clinics that meet the standards above. They return tailored plans and all in prices. You choose, with no pressure.

Free and no obligation. Accredited clinics only. We never sell your details.

We reply within two working days. Your details are never sold.

How we make money: the guides are free and no clinic can pay to be named, ranked or recommended. We never name clinics. Get Matched is an optional service that helps keep the guides free and independent of any one clinic; using it is always your choice and you are never charged. How this works.

Common questions

The things everyone asks.

What is the most important question to ask?

Whether fat is placed only in the subcutaneous layer and never into the muscle. Injecting into the muscle is what causes fatal fat embolism, so a clear answer here is the most important safety check there is.

Why does ultrasound guidance matter?

Real time ultrasound helps the surgeon keep the cannula above the muscle, and it is increasingly recommended by safety bodies to reduce the risk of fat entering the deep veins.

How do I check a surgeon is qualified?

Ask for the surgeon's registration and the facility's accreditation, then verify them on the relevant public register for that country. A clinic with nothing to hide will help you do this.

Does a high volume clinic matter?

Yes. Operating quickly and at high daily volume is linked to higher risk for a BBL. A surgeon doing many cases a day cannot give each the time a safe procedure needs.

What should I get in writing?

The surgeon and facility details, the technique and where fat is placed, the anaesthesia and monitoring, the aftercare and sitting restrictions, and what happens if there is a complication, including who pays.
