Buccal fat removal is permanent. Once the fat pad is surgically extracted, it does not grow back. Unlike general body fat, the buccal fat pad maintains a relatively consistent volume throughout adult life and is less likely to fluctuate with weight changes. Removing it creates a lasting change to your facial contour.
Why the Fat Doesn’t Come Back
The buccal fat pad is a distinct, encapsulated structure sitting between your chewing muscles and your cheek. It’s not the same as the subcutaneous fat layer under your skin that expands and shrinks with your weight. In adults, the buccal fat pad averages about 7 to 11 milliliters per side, and it stays remarkably stable regardless of whether you gain or lose weight. It grows significantly during adolescence, roughly doubling in size between ages 10 and 20, then gradually decreases over the following decades.
When a surgeon removes all or part of this fat pad, the tissue is gone for good. Fat cells in this area don’t regenerate. The remaining facial fat and soft tissue will settle into the space left behind, which is what creates the slimmer, more contoured cheek appearance people are after.
How the Procedure Works
The surgery is done through a small incision inside the mouth, between the cheek and gums. A surgeon applies gentle pressure to the outside of the cheek to push the fat pad toward the incision, then carefully extracts it. The amount removed varies based on your anatomy and goals, but the fat pad itself is a defined structure, not a shapeless deposit, so the surgeon is working with a specific piece of tissue. The incision is closed with dissolvable stitches, and there are no visible scars on the face.
When You’ll See Final Results
You won’t see the full effect right away. Swelling from the surgery makes your cheeks look puffier than before for the first couple of weeks. Most of that swelling resolves within two to four weeks, though subtle puffiness can linger for up to three months. The actual contouring becomes visible around three to four weeks post-surgery, and final results typically settle in between three and six months.
The Aging Factor
Permanence is the biggest selling point of buccal fat removal, but it’s also the biggest risk. Your face naturally loses volume as you age. The buccal fat pad itself shrinks over the decades, and so does the fat layer beneath your skin, along with bone density in the cheeks and jaw. If you remove buccal fat in your 20s or 30s, you may love the result now but find that your face looks gaunt or hollow as you move into your 40s and 50s.
The American Society of Plastic Surgeons has flagged this directly: fullness in the face reads as youthful, and hollowing reads as aging. Trading a full cheek for a hollowed mid-cheek can add a decade or more to your perceived age down the line. This is why many surgeons are cautious about performing the procedure on younger patients with naturally thin faces or minimal buccal fat.
Who Is a Good Candidate
The best candidates are people who are at a stable weight, physically healthy, and nonsmokers. Beyond those basics, the most important factor is having genuinely prominent buccal fat pads. If your round face comes from subcutaneous fat, skin laxity, or your bone structure rather than from oversized buccal fat pads, this surgery won’t give you the result you’re imagining.
People with naturally thin or narrow faces, or those who are still in their teens or early 20s when facial fat hasn’t fully redistributed, are generally not ideal candidates. The concern isn’t just about the immediate result. It’s about what the result will look like in 15 or 20 years when natural volume loss compounds the surgical reduction.
Can It Be Reversed?
Not in the traditional sense. You can’t put the buccal fat pad back once it’s removed. However, if you develop unwanted hollowing years later, surgeons can restore volume using fat grafting. This involves harvesting fat from another area of your body (often the abdomen or thighs) and injecting it into the cheeks. Injectable fillers are another option, though those are temporary and require ongoing maintenance. Neither approach perfectly replicates the natural structure of the original fat pad, but both can meaningfully correct a hollow or gaunt appearance.
Risks and Complications
A systematic review of 308 patients found that about 25% experienced some form of complication, though the vast majority were minor and temporary. The most common issues were swelling (38% of those with complications), limited jaw opening (30%), and pain (19%). These typically resolve within the first few weeks of recovery.
Facial asymmetry occurred in about 12% of complication cases, which can happen if slightly different amounts of fat are removed from each side. More serious but rare complications include injury to the buccal branch of the facial nerve (under 1%), infection (under 0.5%), and damage to the parotid duct, which carries saliva from a major gland to your mouth. The procedure area sits close to several important nerves and blood vessels, which is why surgeon experience matters significantly.
What the Buccal Fat Pad Actually Does
Before deciding to remove it, it helps to know what this structure is for. In infants, the buccal fat pad supports the suckling function, which is why babies have such round cheeks. As you grow, it shifts to a different role: helping your chewing muscles glide smoothly against each other. It also acts as a cushion protecting nearby nerves and blood vessels from external pressure. Removing it doesn’t typically cause functional problems with chewing, but it does eliminate that protective padding permanently.
