In short. Enough fat to harvest, volume loss rather than sagging, and a tolerance for uncertainty: the three requirements that decide candidacy, and what rules it out.
Key points
- Thin, sun-damaged or inelastic skin shows every irregularity, and the areas most prone to visible lumps after fat transfer are exactly the thin-skinned ones: the lower eyelid and the tear trough.
- Good skin quality does not guarantee a smooth result, but poor skin quality makes irregularity more likely and more visible.
- This belongs in the assessment, not in the aftercare.
Candidacy for facial fat transfer comes down to three requirements, and a patient who fails any of them is better served by something else. Unlike many aesthetic operations, this one is not simply a matter of wanting it and being well enough for anaesthesia.
There has to be fat to harvest
The operation needs a donor site. Fat is usually taken from the abdomen or the inner thigh, and the amount available determines how much can be placed. In very thin patients there is sometimes too little to make the operation worthwhile, and no technique compensates for that. A surgeon who examines the donor sites carefully is doing the first part of the assessment properly.
The problem has to be volume loss, not sagging
Fat restores volume. It does not lift. If your concern is that your face has descended — a heavier jawline, a cheek that has moved downward rather than inward — then fat alone will not correct it, and a lift is the operation that addresses it. Many patients have both, and the honest plan may be a lift with fat used to refine volume rather than fat transfer on its own.
Skin quality changes the answer
Thin, sun-damaged or inelastic skin shows every irregularity, and the areas most prone to visible lumps after fat transfer are exactly the thin-skinned ones: the lower eyelid and the tear trough. Good skin quality does not guarantee a smooth result, but poor skin quality makes irregularity more likely and more visible. This belongs in the assessment, not in the aftercare.
You have to be able to accept a range
This is the requirement patients underestimate. Because a proportion of the fat is reabsorbed and the proportion is not knowable, the result is a range rather than a figure. A patient who needs to know in advance exactly how full their cheeks will be is a poor candidate, not because they are unreasonable, but because the operation cannot answer that question and the disappointment is predictable.
Findings that usually rule it out
Uncontrolled diabetes, active infection, a bleeding disorder or certain medicines, and a history of poor wound healing all weigh heavily against it. Smoking impairs the blood supply the transferred fat depends on and worsens survival. A history of poor scarring matters for the donor and recipient sites. And if the real concern is skin texture or pigment, fat changes neither.
Reasons to reconsider
- You want a specific volume, or you need the result to be predictable in advance.
- Your main concern is sagging rather than hollowing, and no lift is being discussed.
- You are not willing to consider a second session if too little fat survives.
What a second session involves is explained under planning for a second session, and the alternative routes are set out in fat transfer or filler.
Frequently asked questions
Can I have fat transfer if I am very thin?
It may not be possible. The operation needs a donor site with enough fat to harvest, and in very thin patients there is sometimes too little to obtain a useful volume. In that situation a filler or a different operation is the honest answer, and a surgeon should say so rather than attempt a harvest that cannot deliver.
Does my age matter?
Not as a number, but the pattern of ageing matters a great deal. Younger patients with inherited hollowing often do very well because the skin is good and the volume loss is localised. Older patients may have both volume loss and sagging, in which case fat alone will not address the sagging.
What if I have had filler in the same area?
It is common and not a barrier, but you must tell the surgeon what was used, when and where. Some fillers persist longer than patients expect, and the assessment of how much volume is needed depends on knowing what is already there. Recent filler in the area may mean waiting.
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.
