Facial fat grafting restores volume by moving your own fat to areas that have hollowed, but a graft is living tissue and it never takes evenly or predictably. Some fat survives, some resorbs, and the final volume can end up too full, too flat, or slightly lumpy or uneven. Revision is its own decision: sometimes the answer is to add a little more where fat resorbed, sometimes to reduce or dissolve an over-full pocket, and very often simply to wait several months while the graft stabilises. This page sets out what fat grafting revision really involves and when patience serves you better.
Garnet is well known for neck-wrinkle and lifting surgery. The facility is excellent and I’m thoroughly satisfied with the friendly consultation and the surgeon’s skill.
Director Baek In-soo, thank you so much. Thanks to you I keep getting told I look younger — it feels like I’ve gone back to my younger days.
I had upper and lower eyelid surgery and I’m really satisfied. The director and the manager were both so kind and clear.
I started with under-eye fat repositioning — the director and the manager are genuinely kind and good at what they do. I’ll be back.
I came on a referral and was very satisfied thanks to the doctor’s kind consultation and clear explanations. The nurses were friendly too.
I kept reading the reviews and came trusting the many mentions of skill and kindness. The clinic was busy with patients and spotless.
Facial fat grafting harvests fat from the abdomen or thigh, processes it, and reinjects it as tiny parcels through cannula entry points into hollowed areas — the temples, cheeks, under-eye, forehead or a love-band under the eye. Because a graft has to establish its own blood supply to survive, the take is never uniform: a portion of every graft resorbs over the first months, and how much survives depends on the area, the technique and how a particular face heals. When that settles unevenly, people come back with a recurring set of concerns.
The most common are volume that ended up too full in one area, or too flat where the fat largely resorbed and the hollow returned. Others notice small firm lumps or nodules under the skin, a contour that looks bumpy or irregular rather than smooth, or an asymmetry where one side took more graft than the other. Occasionally the whole result simply looks over-done — fuller than the face wanted — which reads as heaviness rather than the subtle restoration that was intended.
It is worth separating these motivations, because they lead to very different plans. Early fullness and firmness usually need nothing but time, since part of the graft will resorb; a hollow that persists once the graft has stabilised may need a careful top-up; and an over-full or lumpy area needs reducing or smoothing rather than adding. Adding more fat to a face that is still resorbing is one of the most common avoidable mistakes.
Most of what alarms people in the first weeks and months after a fat graft is normal and temporary. In the early phase the graft is deliberately over-filled to allow for resorption, so the face looks fuller than the final result and can feel firm, slightly lumpy or uneven as swelling and the transferred fat settle. A cheek or under-eye that looks over-done at three weeks can look natural by three months as part of the graft resorbs and the swelling falls, and the page on fat grafting swelling and bruising walks through what is expected and over what timeframe.
Asymmetry in the early phase is just as misleading. Two sides of a face rarely swell or resorb at exactly the same rate, so a result that looks uneven at one month can even out by three or four. Judging the final volume before the graft has stabilised leads people to chase a problem — either a hollow that has not finished filling or a fullness that has not finished resorbing — that would have resolved on its own, which is why an honest surgeon will usually ask you to wait and reassess.
What does not reliably settle on its own is a genuine hollow where too little fat survived, a persistent firm lump or nodule, a fixed contour irregularity, or an over-full area that remains heavy once the graft has clearly stabilised. These are the concerns where revision is reasonably considered — and the first step is simply telling them apart from the normal resorption and settling above, which takes months, not weeks.
Fat graft revision is not one operation but a spectrum, and matching the response to the problem is the whole skill. Where the graft under-took and a hollow returned, the answer is usually a top-up: a smaller, targeted micro-fat graft into the specific area, sometimes supplemented as in the original technique, placed conservatively because a revision graft resorbs too and over-filling again just repeats the problem. A modest under-correction can also sometimes be evened out rather than fully re-grafted.
Where the graft over-corrected and an area stayed too full, the answer is reduction rather than addition. A soft, diffuse over-fullness can often be refined with fine cannula liposuction to remove a small amount of grafted fat and smooth the contour; a small, discrete deposit may instead be reduced with careful dissolving where appropriate. A firm nodule that persists is assessed on its own terms — sometimes it softens with time, sometimes it is best removed.
Persistent asymmetry is corrected by adjusting toward balance — adding to the flatter side, reducing the fuller side, or both — rather than treating each side in isolation. The honest through-line is that revision refines an existing graft in small, deliberate steps; the aim is a smooth, balanced contour, not a dramatic change, and the smallest correction that solves the specific problem is preferred over another full session.
Timing is the most important decision in fat graft revision, and for most concerns the honest answer is to wait — and to wait longer than people expect. Because a graft keeps resorbing for months, the final volume is simply not knowable in the first weeks. Adding fat to an area that has not finished resorbing, or removing fat from one that has not finished settling, means operating on a moving target and risks over-shooting in the opposite direction.
As a general principle, a surgeon prefers to let the graft stabilise before deciding on revision — commonly around three to six months, once resorption has largely run its course and the true surviving volume is clear. Assessing a stabilised face rather than a freshly grafted, swollen one is what allows a small, accurate correction instead of a guess. This is one procedure where rushing back too soon reliably makes the outcome worse.
There are few urgent scenarios with fat grafting, but a firm, tender or growing lump, redness, or signs of infection are reviewed promptly rather than left to settle. For the far more common question of whether a hollow will fill or a fullness will resolve, patience is the tool: the page on how long fat grafting lasts explains the normal arc of survival, so you can tell a graft that is still settling from one that has genuinely under- or over-delivered before deciding to touch it.
A careful revision begins with working out what was done before — which areas were grafted, roughly how much, whether the technique was supplemented, and how long ago — because that shapes what is safe to do next. For an under-corrected area, the surgeon harvests a small amount of fresh fat from the abdomen or thigh, processes it, and places a conservative top-up through cannula entry points into the specific hollow, respecting the fat that already took. Because fat grafting uses cannula access rather than incisions, this does not usually add visible scars.
For an over-full area, the approach is reduction: fine, controlled cannula liposuction removes a measured amount of grafted fat and smooths the contour, or a small discrete deposit is reduced by careful dissolving where that is appropriate. A persistent nodule is treated on its own terms. Because grafted fat sits within tissue that has already healed once, revision is done slowly and conservatively, checking contour as it goes rather than making a large change in one pass.
The two approaches can be combined — adding to a flat area while refining an over-full one to balance the two sides. Recovery from a revision graft resembles a smaller version of the original, with the same slow settling to allow for, and the fat grafting recovery timeline covers that pattern. Revision is more about judgement than force: the goal is to nudge an existing result toward a smooth, balanced contour with the smallest appropriate step, not to re-graft aggressively in the hope of a bigger change.
Garnet is a single-surgeon clinic in Apgujeong, Seoul, with extensive experience in facial fat grafting. Dr. In-Soo Baek is a board-certified plastic surgeon (Korean medical licence no. 77407) and the only operating doctor — he assesses each revision case himself, plans it himself, performs it himself and reviews every follow-up, with structured reviews at one, three and six months. For revision, that continuity matters: the surgeon who examines your earlier graft is the one accountable for the plan and the result.
Revision assessment at Garnet is deliberately unhurried and honest. That includes being willing to say that an early over-fullness will resorb and needs time rather than reduction, that a returned hollow can be topped up conservatively, or that a lumpy or over-full area should be refined rather than re-grafted. There is no consultation or CT fee and no pressure to book same day, because a sound fat graft revision depends on assessing a stabilised face, which cannot be rushed.
If you are considering correcting an earlier facial fat graft from abroad, you can begin without travelling. Send your history and photos for an honest pre-assessment, and read the fat grafting international patient guide for how stay length and remote follow-up are handled — bearing in mind that revision is usually best timed several months after the original graft.
Send photos and your question before you travel. An English-speaking coordinator reviews every enquiry and replies with honest guidance on whether surgery is appropriate, the likely plan and timing.
