Does Buccal Fat Removal Age Your Face? What the Evidence Says

Buccal fat removal can make a face look older, but it does not do so in everyone. The risk is greatest when too much fat is removed, when the face is already narrow, or when the fullness was never caused by buccal fat in the first place. Johns Hopkins Medicine notes that the face loses fat and muscle volume naturally with age, that this can intensify the slimming effect of an earlier reduction, and that over-removal can give a prematurely gaunt look.¹

What makes the question difficult is that nobody has followed large groups of patients for decades. A systematic review of the published research found only four eligible studies and noted that long-term follow-up data are lacking.³ This guide explains what is known about how buccal fat and the rest of the face change over time, who is a poor candidate and why a conservative plan matters.

What buccal fat is and why it matters

Buccal fat is a pad of fat in the cheek below each cheekbone, between the cheekbone and the jaw, and its size varies from person to person.^1,2 The cheek branches of the facial nerve run across its surface, which is why care is needed to protect them when the fat is removed.⁵

In a young face a full buccal pad can make the lower cheek look round. Johns Hopkins also notes that some buccal fat in the cheek helps keep a smoother, more youthful appearance as a person ages.¹ The tissue that makes a face look full at 25 also shapes how it looks at 55.

How the face changes with age, and where buccal fat fits

Facial ageing is not only about skin. StatPearls describes the most visible changes as fat loss and descent, which lead to tear troughs, deeper folds between the nose and mouth and jowls, together with gradual loss of bone.⁵ As other fat compartments thin, the cheek can look flatter even if nothing was removed.

Patient information often says that buccal fat diminishes with age,² but imaging data are more mixed. In a retrospective cross-sectional CT study of 120 adults, buccal fat volume measured on the left side was higher in the 30–49 and over-50 age groups than in people aged 18–29; it was lower in women and higher in overweight people.⁴ In older faces the pad can also bulge forward (pseudo-herniation) and contribute to jowls.⁵ So the risk of a hollow look later probably comes less from the pad shrinking on its own and more from the rest of the face losing volume around a cheek that has already been thinned.^1,5

Does buccal fat removal age your face? What research shows

A systematic review published in 2021 screened 1,413 references and found only four studies eligible for analysis. In those studies 84.6% of patients rated their facial contour as much better and seven complications were reported across 134 procedures, but the authors described the evidence as scarce and of low quality and noted a lack of published long-term follow-up.³

Early satisfaction is documented; how these faces look 20 years later is not. Any claim that the procedure is either safe or harmful in the very long term therefore goes beyond the evidence.

Who is a poor candidate?

Good candidates are usually healthy, at a stable weight and bothered specifically by fullness of the lower cheeks.² People with a narrow face are often poor candidates because removal can accentuate the narrowness, and, according to Cleveland Clinic, older patients because buccal fat diminishes with age; Johns Hopkins adds that in older adults removing it without other procedures can lead to sagging of the lower face.^1,2

Age matters at the young end too. Most doctors recommend waiting until 18–20, because the face shape and buccal fat pads change as the face matures.¹ Not all round cheeks are buccal fat: a strong chewing muscle (masseter), general facial fat or bone shape can look similar, and buccal fat removal does not change muscle or bone. Our buccal fat removal page describes these distinctions and the operation itself.

What “conservative removal” means in practice

Buccal fat pads do not grow back, so the change is long-lasting; other facial fat can still expand with significant weight gain.¹ In the only study in the systematic review that measured the amount removed, the mean was about 2.7 mL, with a range of 1.8–4.9 mL, so this figure rests on limited data.³ A conservative plan removes only part of the pad, judged against the width of the face, the cheekbones and the likely direction of ageing, and in some faces the honest advice is not to remove any.

Removed fat cannot simply be put back; volume can be added later in other ways, but it is better not to need it. In an older face where heavy lower cheeks come from descended tissue, the plan changes: during a deep plane facelift, buccal fat that contributes to jowling can be reduced conservatively as part of the lift.⁵ Our guide to deep plane and SMAS facelifts explains that technique.

Alternatives worth considering

If the concern is general facial fullness, stabilising weight comes first, because the result of removal is less noticeable in people who are overweight.¹ Cheek liposuction, in which fat is removed through a narrow tube with suction, is another approach Johns Hopkins describes.¹ When the problem is a soft jawline or fullness under the chin, the question is usually the neck rather than the cheek; see double chin: liposuction or neck lift.

For deep smile lines, Johns Hopkins notes that a facelift is a more long-lasting solution.¹ Non-surgical treatments, such as fillers, are also used to change face shape; they are separate decisions with their own risks and are not covered here.
