In short. Placing more fat than the result requires looks like an error and is standard practice. Why it happens, how long it lasts, and what that means for you.
Key points
- The first is judging the result in the first month, when the appearance is a combination of swelling, deliberately placed extra volume and bruising, none of which reflects the outcome.
- The second is asking for the excess to be removed.
- It cannot be removed selectively at that stage, and acting on the impression of the first fortnight is how patients end up under-corrected a year later.
Understanding over-correction is the single most useful thing a patient can do before facial fat transfer, because the first two weeks of the recovery look wrong by design. A face that is deliberately overfilled reads as a mistake to the person looking in the mirror, and it is standard technique.
Why it is done
Because a proportion of the fat will not survive. If the surgeon placed exactly the volume wanted, the result after reabsorption would be under-corrected in nearly every patient. Placing more than the target means that the fat which takes leaves the face at or near the intended volume. How much over-correction is a judgement based on the area treated, the technique and the patient's tissues.
What it looks and feels like
The treated areas look fuller than planned, sometimes markedly so, and the face can feel tight and heavy. The skin may look shiny over the fuller areas because it is stretched, and the cheeks may look rounder than the patient's own anatomy suggests. Bruising and swelling add to it. This resolves over weeks, and the change between the second week and the third month is larger than most patients expect.
The two mistakes patients make at this stage
The first is judging the result in the first month, when the appearance is a combination of swelling, deliberately placed extra volume and bruising, none of which reflects the outcome. The second is asking for the excess to be removed. It cannot be removed selectively at that stage, and acting on the impression of the first fortnight is how patients end up under-corrected a year later.
How long it lasts
Swelling settles substantially within two to three weeks. The reabsorption of fat that is not going to survive runs over roughly three months. By three months the face looks close to its lasting result, and from six to twelve months the volume is called final. Lumps and unevenness also soften over the first months, which is why a texture complaint raised at three weeks is usually answered by waiting.
What it means for your expectations
Expect to dislike the first fortnight, and expect that what you see then is not the result. Expect to be told to wait, and understand that the instruction describes how the operation behaves rather than postponing a difficult conversation. If you cannot tolerate looking overfilled for several weeks, this operation will be difficult for you regardless of the outcome.
Do not
- Ask for the excess to be removed in the first weeks. It cannot be done selectively, and it leads to under-correction.
- Judge the result from photographs taken at two weeks, when the appearance is transient by design.
- Accept a plan that does not mention over-correction at all before you consent.
What over-correction compensates for is explained under how much fat survives, and the plan for topping up the volume is set out in why a second session is common.
Frequently asked questions
How long will my face look overfilled?
The fullness is most obvious in the first two weeks, when swelling and the deliberately placed extra volume overlap. It settles substantially over the following weeks, and by around three months most of the fat that is going to be reabsorbed has gone. The intended result is judged from three months, not from the first fortnight.
What if I like the fuller look and it goes away?
That is a common response, and it is one of the reasons a second session is discussed in advance. If the volume that remains is less than you want, a further session can add to it. Fat transfer is built up rather than reduced, which is why erring on the fuller side is preferred to erring on the empty side.
Does over-correction cause lumps?
Over-correction is about volume, not about how the fat is placed. Lumps come from placing fat in deposits too large to be reached by a blood supply, or from uneven placement, rather than from placing a lot of fat in total. A surgeon can place a generous volume in many small parcels and still produce a smooth result.
Risks & Limitations
- A proportion of the transferred fat is always reabsorbed. How much cannot be predicted, and a second session is common rather than exceptional.
- Irregularity, lumps or visible unevenness, which is more likely in thin-skinned areas such as the lower eyelid and tear trough.
- Fat necrosis and oil cysts where transferred fat fails to establish a blood supply; these may need aspiration or occasionally removal.
- Under-correction, the commonest reason for dissatisfaction, because less fat survived than was hoped.
- Bruising, swelling and soreness at the face and the donor site, with donor-site numbness and contour irregularity that can persist.
- Scars at the donor and recipient sites are permanent and mature over 6–12 months.
- Infection and bleeding; rare but serious risks include injury to structures near the injection site and embolic complications.
- General risks of anaesthesia, which a hospital setting manages but cannot remove.
When to Seek Care
- Difficulty breathing or shortness of breath — seek emergency care immediately.
- Rapidly increasing swelling, or a tense, painful, tight area.
- Fever above 38 °C, spreading redness, warmth, or discharge from an incision.
- A new lump that is painful, hot or growing, rather than one that is softening over months.
- Sudden change in vision after facial fat transfer.
