Does buccal fat removal cause premature facial aging later in life?
Short answer
This is a legitimate and widely discussed concern, but there is currently no long-term clinical study that directly proves buccal fat removal causes premature aging. Experts do warn that removing too much volume in younger patients could worsen the natural hollowing that comes with aging, which is why careful patient selection is considered essential.
What the research shows
The buccal fat pad is a significant source of midface volume. One cohort study measuring fat pad volumes noted that removing only the excess portion is important because this structure provides significant volume in the midface that can be difficult to restore once aging affects the surrounding soft and bony tissue [2]. An earlier study similarly cautioned that only submuscular buccal fat excision should be performed in carefully selected patients specifically to avoid late secondary deformities [3].
A 2018 systematic review of the available literature found that no study had evaluated facial aging or long-term effects of buccal fat removal, meaning the harmless or harmful nature of the procedure on long-term aging simply has not been proven either way [5].
Adding to the concern, one report noted that because the buccal fat pad is connected to the temporal fat compartment, reducing it can also lead to volume depletion in the temples, an area that naturally hollows with age [6]. Some surgeons have begun transferring the removed fat to the temples at the same time to compensate for this [6].
Why the concern exists
Facial aging naturally involves significant volume loss throughout the cheeks and midface [1]. Surgeons who use buccal fat as a flap (repositioning rather than discarding it) do so precisely because this fat provides useful autologous, living tissue to restore volume to areas that deflate with age [4]. This reinforces the idea that removing this tissue permanently in a young person could accelerate the hollow, gaunt appearance that tends to develop in older age. However, this remains expert opinion and biological reasoning rather than proven long-term outcome data.
What this means for you
The honest bottom line is that no high-quality long-term study has confirmed or ruled out premature aging from this procedure [5]. What experts do agree on is that patient selection matters greatly. The procedure appears most appropriate for people who genuinely have excess buccal fat volume, not for those who simply desire more defined cheekbones regardless of their natural anatomy [2] [3]. If you are considering this surgery, asking your surgeon about your specific anatomy, long-term volume consequences, and whether partial rather than complete removal is appropriate for you are all reasonable questions.
What to ask your surgeon
- Am I actually a good candidate based on my buccal fat volume, or is my anatomy already lean?
- How much fat do you plan to remove, and why that amount?
- What happens to my face if I lose more volume naturally as I age in my 40s and 50s?
- Would you consider a partial removal or a fat-repositioning approach rather than full excision?
