In short

Buccal fat removal is surgery that removes part of the fat pad deep in the cheek through an incision inside the mouth. It cannot be undone, carries risks to nearby nerves and the saliva duct, and can leave a face hollow with age. Many full faces are due to masseter muscle, fat under the skin, laxity or chin shape, which non-surgical options address. IN Eternity Clinic does not perform surgery.

  • What buccal fat is: a fat pad deep in the cheek between the masseter and the inner cheek muscle.
  • The surgery: part of the pad is removed through an incision inside the mouth; IN Eternity Clinic does not perform it.
  • Key risks: swelling, bleeding, infection, asymmetry, rare duct or nerve injury, and hollowing later in life.
  • Evidence: limited; a 2018 review found few case series and no long-term follow-up.
  • Often not buccal fat: masseter bulk, fat under the skin, laxity, parotid enlargement or a short chin.
  • Non-surgical options: jaw slimming injections, Time Freeze Laser LCLR®, VF Lift – Vertical Facelift, HIFU, chin filler.

The surgery

What is buccal fat removal?

The buccal fat pad is a body of fat that sits deep in the cheek, between the chewing muscle (masseter) and the muscle of the inner cheek (buccinator), with extensions that reach towards the temple and the jaw. It helps cushion the muscles of chewing and contributes to the soft fullness of the lower cheek, especially in younger faces.

Buccal fat removal (buccal fat pad excision) is a surgical operation to take out part of that fat. It is done through a small incision inside the mouth, on the inner cheek, so there is no scar on the face. The operating doctor opens the thin layer over the fat, teases part of the pad out and closes the incision with stitches. It is usually done under local anaesthetic, sometimes with sedation or general anaesthetic, by plastic surgery or oral and maxillofacial specialists.

Recovery involves swelling for one to several weeks, a soft diet and careful mouth hygiene while the incision heals; the final shape settles over months. IN Eternity Clinic does not perform buccal fat removal or any other surgery. This page explains the operation factually, then the more common question at consultation: whether the fullness is buccal fat at all, and what non-surgical options can do when it is not.

Risks and evidence

Buccal fat removal in Singapore: risks and what the evidence shows

Because the operation is small and the scar is hidden, it is often presented as minor. The structures around the fat pad are not minor: the parotid duct, which carries saliva into the mouth, runs close by, and so do branches of the facial nerve that move the cheek and upper lip.

A general summary of reported risks. A surgical specialist explains the risks for an individual case.
RiskWhat it means
Swelling, bruising, discomfortExpected for days to weeks
Bleeding or a collection of blood (haematoma)Uncommon; may need drainage
InfectionUncommon; treated promptly
Injury to the parotid ductRare; can cause a saliva collection or leak
Injury to facial nerve branchesRare; weakness of the cheek or upper lip, usually temporary
AsymmetryOne side different from the other
Over-removal and hollowing later in lifeThe face loses fat naturally with age; a face that looked full at 25 can look gaunt at 45

The evidence base is thinner than its popularity suggests. A 2018 review of published data found only two case series of more than five patients undergoing buccal fat excision for cheek contouring, a total of 53 people, and none with long-term follow-up of satisfaction or results. A volumetric study found that only part of each fat pad can sensibly be removed, and that careful selection matters. Older surgical reviews make the same point: the fat pad has a role in the shape of the face, and removal is irreversible.

Is it buccal fat?

When a full face is not buccal fat at all

Many people who ask about buccal fat removal turn out to have fullness from something else. A wide or round lower face has at least five possible causes, and they often combine.

Several causes are often present at once. The examination decides which dominates.
What you seeLikely causeSimple clueRemoving buccal fat would
Width at the angle of the jawAn enlarged masseter (chewing muscle)A firm bulge that hardens when you clenchNot change it
Soft, pinchable fullness over the cheeks and jawSubcutaneous fat under the skinChanges with weight; pinchable between fingersNot change it
Heaviness along the jawline, jowlsLaxity and descent of tissueLooks better when you lie down or lift the skin gentlyMake it worse over time
Fullness in front of and below the earParotid gland enlargementSwelling in front of the ear; sometimes with eatingNot change it; needs a medical check
Fullness in the lower inner cheek, more when smilingBuccal fat padFullness between cheekbone and jaw, inside the outer contourReduce it, irreversibly
A short, recessed chin making the face look widerChin and jaw proportionProfile shows a weak chinNot change it

This is why the same complaint, “my face is too round”, leads to very different plans. A full guide to the causes of lower-face width is in what widens the lower face, and options for each cause are set out in face slimming in Singapore.

Non-surgical options

Non-surgical alternatives to buccal fat removal at IN Eternity Clinic

Each non-surgical option targets one cause. None removes the buccal fat pad itself, and none should be used to chase a gaunt look in a face that does not have excess to lose.

Options are combined only where more than one cause is present. Suitability is decided at assessment.
If the main cause isOption at IN Eternity ClinicWhat it doesLimits
Masseter bulkJaw slimming injections (a prescription muscle-relaxing medicine, given by the doctor)The muscle slims gradually over weeksRepeated to maintain; does not change fat or bone
Subcutaneous fat in the lower faceTime Freeze Laser LCLR®, which includes point-zone fat reductionGradual reduction of localised fat with skin tighteningUnsuitable for lean faces; change builds over weeks
Laxity in a lean faceVF Lift – Vertical Facelift on Volnewmer radiofrequencyTightens along planned vertical vectors without removing volumeModest, gradual change
Laxity with early jowlingHIFU or UltherapyFocused ultrasound firms the support layerNot for heavy skin excess
A short or recessed chinChin filler to rebalance proportionMakes the lower face read narrowerHyaluronic acid filler is temporary
Fullness under the chinDouble chin treatment matched to fat or laxitySharpens the jaw–neck angleDepends on the cause

The order matters. Where masseter bulk and fat are both present, the muscle is usually addressed first, because a slimmer jaw angle changes how much fat reduction is needed. Where laxity is part of the picture, removing volume without supporting the skin can make jowls look heavier, so lifting is planned alongside.

“Buccal fat is the one part of a round face you cannot put back once it is gone. Before anyone removes it, it is worth being sure it is the reason the face looks full.”
— Dr Sin Yong, Medical Director, IN Eternity Clinic
Thinking ahead

Will a slimmer face now look older later?

Faces lose fat with age, in the temples, cheeks and around the mouth, and bone recedes slowly. A face that is full in the twenties often looks youthful in the forties for exactly that reason. Removing or reducing fat in a face that is already lean, or that will become lean, can bring forward the hollow, tired look that most people later spend money trying to correct.

This applies to non-surgical fat reduction as well as to surgery: heat-based fat reduction in a lean face can hollow it. At IN Eternity Clinic the question asked is not “can fat be reduced?” but “should it be?”. If the answer is no, the plan may be to define rather than slim: a stronger chin, a firmer jawline or a slimmer jaw angle can change how full a face looks without taking volume away. The jawline and face shape options are summarised in V-shape face in Singapore.

At assessment

What Dr Sin Yong looks for

  • The clench test. A bulge at the jaw angle that hardens on clenching points to the masseter.
  • The pinch test. Fat that can be pinched under the skin is subcutaneous, not buccal.
  • Rest and smile. Where the fullness sits at rest and how it moves when you smile.
  • Lying and sitting. Fullness that improves when lying back suggests laxity rather than fat.
  • Weight history and photographs. How the face has changed with weight and age, and how it looked ten years ago.
  • Profile. Chin projection and jaw shape, which change how wide the face reads from the front.
  • Anything glandular. Swelling in front of the ear, or fullness that changes with meals, is examined medically.

General clinical observations used at consultation; they describe what is checked, not any individual result.

When this is not cosmetic

When facial fullness needs a medical check

Most facial fullness is anatomy, weight or ageing. Some patterns are medical and are assessed before any cosmetic plan.

These are referred for diagnosis first. A cosmetic plan, if still wanted, follows once the cause is clear.

Cost

How much does buccal fat removal cost compared with non-surgical options?

Buccal fat removal is a surgical procedure priced by surgical practices, including theatre and anaesthetic fees; IN Eternity Clinic does not offer it and does not quote for it. Non-surgical options are priced by treatment and number of sessions, and some, such as jaw slimming injections, are repeated to maintain. Because the right option depends entirely on the cause of the fullness, the plan and its cost are explained after assessment. The consultation fee at IN Eternity Clinic is S$120, waived with any medical treatment.

Questions

Frequently asked questions

Does IN Eternity Clinic do buccal fat removal?

No. Buccal fat removal is surgery, and IN Eternity Clinic does not perform surgery. The clinic assesses whether facial fullness is due to buccal fat, muscle, fat under the skin, laxity or proportion, and offers non-surgical options where they suit. Where surgery may be the right route, a surgical opinion is suggested.

Does buccal fat grow back after removal?

No. The fat that is removed does not grow back, which is why selection matters. The rest of the face keeps ageing and losing fat naturally, so a face that looks pleasingly slim soon after surgery can look hollow years later.

Can buccal fat be removed without surgery?

No non-surgical treatment removes the buccal fat pad itself, because it sits deep in the cheek. Non-surgical options target the other common causes of fullness: masseter muscle, fat under the skin, laxity and chin proportion.

How do I know if I have too much buccal fat?

Buccal fullness sits in the lower inner cheek, between the cheekbone and jaw, and is often more visible when smiling. A firm bulge at the jaw angle on clenching is the masseter, and pinchable fat is subcutaneous. An examination tells them apart.

What are the risks of buccal fat removal?

Swelling and bruising are expected. Less common risks include bleeding, infection, asymmetry, and rarely injury to the parotid duct or facial nerve branches. The longer-term risk is hollowing as the face ages. A surgical specialist explains risks for an individual case.

Will jaw slimming injections make my face less round?

If the width comes from an enlarged masseter, jaw slimming injections slim the muscle gradually over weeks and can make the lower face look narrower. They do not change fat, buccal fat or bone, so the cause is confirmed first.

Is buccal fat removal popular in Singapore?

It is widely discussed online, often in short videos showing early results. Published evidence on long-term outcomes is limited. Anyone considering it should see a qualified surgical specialist and ask about the long term, not only the first months.

Can fat-reduction treatments make my face look older?

They can, in a face that is already lean or will become lean with age. Heat-based fat reduction removes volume that the face may need later. That is why the question at assessment is whether fat should be reduced, not only whether it can be.
