In short. Removing volume from under loose skin leaves more skin relative to what is beneath it. Why the fold can deepen, and who this rung is actually for.
Key points
- Before, the volume beneath the skin filled the covering out.
- Afterwards, the covering is the same and the volume is less, so there is relatively more skin than there was.
- This is why an abdomen whose skin has lost its elasticity can look looser after fat is removed than it did before, which is the opposite of what the patient expected.
Removing fat is the commonest thing done to an abdomen and, on the wrong abdomen, the thing that makes it look worse. The reason is simple geometry rather than a failure of technique.
The covering and what it covers
Skin is a covering, and it is sized to what is beneath it. When the volume under the skin is reduced and the skin itself is unchanged, the same amount of skin now covers less. It has to go somewhere, and it drapes — which is what a fold is.
What decides the outcome
How much recoil the skin has. Skin that still returns to shape after being stretched will follow the new contour and the abdomen reads tighter. Skin that no longer returns will not follow it, and the fold becomes deeper than it was. Nothing about the fat removal is different in the two cases; only the skin is.
Why the fold can look worse afterwards
Before, the volume beneath the skin filled the covering out. Afterwards, the covering is the same and the volume is less, so there is relatively more skin than there was. This is why an abdomen whose skin has lost its elasticity can look looser after fat is removed than it did before, which is the opposite of what the patient expected.
Who this rung is for
A patient with a discrete layer of fat, skin that still holds its shape, and a stable weight. It is the situation in which removing fat does what it says, and it is established by lifting and releasing the skin rather than by looking at the abdomen in a mirror.
Who it is not for
A patient whose skin no longer recoils, whose fold is made of skin rather than fat, or whose weight is still moving. In each of those cases the appearance after removal is likely to be less good than before it, and the honest answer is to address the skin or to wait.
What the assessment establishes
How much recoil the skin has, how thick the fat layer is, how deep the fold over the belt line is, and whether the abdominal wall also needs attention. Those four findings decide whether fat removal, skin removal, both, or neither is the right answer — and the sequence, where both are involved, is set out before anything is done.
See a doctor rather than proceeding if there is
- A rash in the fold that keeps returning, or skin that is raw or weeping.
- A lump in the abdominal wall that does not reduce when you lie down.
- Weight change without a cause, or a change in the skin over weeks.
What the non-surgical rung does and does not change is set out in What Firming Devices Do Not Do for an Abdomen. What keeps a result over the years is explained in Maintaining an Abdominal Result, and What Reverses It.
Frequently asked questions
Does removing fat ever improve the appearance of loose skin?
It can, where the skin still has enough recoil to follow the new contour. That is the finding that decides it: skin that springs back will hold the shape beneath it after volume is removed. Skin that stays where it is put will drape further, and the fold will be deeper. The same procedure produces both outcomes in different people.
Is this a complication or an expected result?
It is an expected result of the tissue, not a complication of a technique. Skin is a covering, and when what it covers becomes smaller the covering has relatively more of itself to drape. It is predictable from an examination, which is why the recoil of the skin is tested before anything is offered rather than afterwards.
What should be done instead if the skin is loose?
The question becomes whether skin needs removing, and whether the abdominal wall also needs repairing. That is a different operation with a longer scar and a longer recovery, and it is the only one that addresses skin that has lost its recoil. Where the skin still holds, fat removal remains a reasonable option on its own.
Risks & Limitations
- Removing fat from under loose skin leaves more skin relative to what is beneath it, so the fold can look deeper.
- No cream, device or fat-removal procedure removes skin. Only excision does.
- Scars from skin removal are long and do not disappear. They mature over 6–12 months.
- Further weight change and a further pregnancy can alter a result.
When to Seek Care
- A rash in the fold that keeps returning, or skin that is raw or weeping.
- A sore in the fold that will not heal, or skin that is breaking down.
- A lump in the abdominal wall that does not reduce when you lie down.
- Difficulty breathing or chest pain — seek emergency care immediately.
