The skin of the lower eyelid is among the thinnest on the body. That makes the under-eye the place where fat grafting is most likely to show: a small excess becomes a ridge, a cluster of grafted fat becomes a visible bead, and fullness that would be invisible in the cheek reads as puffiness. These are some of the most common reasons people look for help after fat transfer.
Short answerUnder-eye fat grafting complications are usually a visible ridge, small lumps or persistent puffiness below the lower lid, because the skin there is too thin to hide any excess or irregularity. Grafted fat cannot be dissolved, so the first step is telling graft from filler, eye bags and fluid, ideally with ultrasound. Small superficial excess may be reduced carefully without surgery; discrete lumps and larger excess are often better managed by an oculoplastic surgeon.
Key facts
Why the under-eye
Thin lid skin shows any excess, clumping or edge
Common complaints
A ridge, visible beads or lumps, puffiness that does not change through the day
Often confused with
Eye bags (fat herniation), fluid, or under-eye filler
Hyaluronidase
Dissolves HA filler only; no effect on grafted fat
Assessment
History, examination at rest and smiling, ultrasound where useful
Surgical route
Oculoplastic surgeon for discrete lumps or larger excess
Why the under-eye is the least forgiving place for a graft
In the cheek, a little extra fat blends into the surrounding volume. Under the eye there is almost nothing to blend into: the lid skin is thin, the area moves with every blink and smile, and light falls across it from above. Small differences in how the graft has taken, or a few clusters that survived better than others, show as an edge, a ridge or beads.
Reviews of facial fat grafting complications list contour irregularity as the most common complaint overall, about one in five reported adverse events, and the periorbital area is where it is most visible.

What you see
Possibly
What separates it
A smooth ridge below the lid
Graft excess; filler
History and ultrasound
Small visible beads or lumps
Graft clusters; fat necrosis or oil cysts
Examination and ultrasound
Puffiness worse in the morning
Fluid; sometimes filler
Changes through the day
A bulge that grows when looking up
Eye-bag fat herniation
Examination in different gaze positions
How it is assessed
The first step is working out what is there. Many under-eyes that have had fat have also had filler, and both can sit over natural fat pads that are themselves starting to bulge. A careful history, examination at rest and when smiling, and ultrasound where the picture is unclear separate graft, filler, eye-bag fat and fluid. Hyaluronic acid filler, if present, can be dissolved; grafted fat cannot.
What can be done
Where the excess is small and superficial, and the graft has stabilised, careful energy-based reduction may be considered; around the eyelids Dr Sin Yong keeps laser settings conservative and uses eye protection, and Time Freeze Laser LCLR® is planned zone by zone rather than across the whole lid. Where the problem is a discrete firm lump, a larger excess, or fat that has been placed close to the lid margin, an oculoplastic surgeon is usually the right person, and he refers.
The full approach to an overfilled graft, including microliposuction and the other published options, is on fat grafting correction.
When to be seen promptly
A hard, red, tender or growing lump, swelling of the lid with pain, or any change in vision after an injection near the eye needs prompt medical attention.
“Under the eye, the question is never how much volume. It is whether the skin can hide what has been placed, and very often it cannot.”
Dr Sin Yong
Frequently Asked Questions
Not with an enzyme. Grafted fat is living tissue. Excess is reduced rather than dissolved, and under the eye that is done cautiously, with surgical removal by an oculoplastic surgeon where appropriate.
Some early irregularity settles as swelling resolves. Lumps that persist once the graft has stabilised usually need assessment, and some, such as oil cysts, have specific treatments.
Often both. History and ultrasound are the most reliable way to tell, which matters because only hyaluronic acid filler can be dissolved.
Until the graft has stabilised, usually several months. A firm, red or growing lump should be seen sooner.
