Fat Transfer: What It Is, How Long It Lasts, and What to Expect

Liposuction, lipofilling, and fat transfer: are they the same?

The difference is what happens to the fat. Liposuction removes it to reshape the donor area. Fat transfer adds another step: preparing some of that fat and using it as a graft elsewhere. Lipofilling is another common term for filling an area with your own fat.

This is not a weight-loss treatment. The amount that can be harvested and safely grafted depends on your anatomy, goals, and the tissues' capacity to receive it.

How is fat transfer performed?

The procedure has three stages. Although the overall approach is similar, processing, injection plane, anesthesia, and operating time are adapted to the treatment area and any associated surgery.

1. Harvesting the fat

   Fat is removed with liposuction cannulas from areas such as the abdomen, thighs, or hips. The choice is not based only on where there is excess fat: we also plan the donor area's final contour.

2. Preparing the graft

   The usable fraction is separated from excess fluid and other components. Settling, centrifugation, or other systems may be used depending on the indication. In our buttock surgery, we use settling. The volume harvested is not the same as the volume finally prepared for grafting.

3. Distributing it at the recipient site

   Fat is carefully placed in the appropriate tissues for each region. In the breasts, it is distributed in small deposits at different points; in the buttocks, the injection plane must be exclusively subcutaneous. The aim is not to inject all available fat or concentrate it in a single space.

Fat transfer to the breasts and buttocks: different goals

Both procedures use your own fat, but they should not be described as the same operation. Expectations about volume, recovery, and safety should not be transferred from one to the other.

Fat transfer to the face and hips

In the face: restoring volume without overfilling

Grafting may address volume loss in the cheeks, temples, and selected under-eye or nasolabial transitions. The aim is to restore proportion and a more rested appearance, not indiscriminately fill every wrinkle. Not all expression lines are caused by volume loss.

Although fat has also been used in the lips, we generally prefer hyaluronic acid for this area because it can be adjusted and dissolved. Nodules or cysts after fat grafting can be difficult to treat. The choice requires a specific assessment; no filler is risk-free.

Our page on facial lipofilling with your own fat explains the indications and limitations of this application.

In the hips: softening transitions

Fat can fill depressions and improve the relationship between the waist, hips, and buttocks. It changes soft tissue, not bone structure: the result must respect your anatomy, and we cannot promise a silhouette identical to a reference photo.

Who may be a candidate?

Wanting to remove fat from one area and place it in another is not enough. During consultation, we assess your health, medical and surgical history, available fat, tissue quality, and goals.

• Enough donor fat: it must be possible to harvest it without harming that area's contour. A slim person may have enough fat for a small correction but not for extensive body augmentation.
• Suitable recipient tissues: not all harvested fat can be safely grafted.
• A reasonably stable weight: major changes can alter the result.
• Realistic expectations: accepting reabsorption, changes over several months, and the possibility of another session.

The advantage is using your own tissue while treating both the donor and recipient areas. Limitations include fat availability, graft variability, and complications at both sites. A natural-looking result is a planning goal, not a guarantee simply because the fat is autologous.

How long does fat transfer last, and how much fat is reabsorbed?

The part of the graft that integrates may remain long-term. However, not all injected fat survives. During the first months, swelling resolves and some of the graft is reabsorbed: the appearance in the first few days does not predict the final volume.

No retention percentage can be guaranteed for every person and treatment area. The systematic review of breast augmentation with fat reports variation between studies; its figures do not predict an individual's outcome and cannot automatically be applied to the face or buttocks.

“Long-lasting” therefore does not mean that shape and size will stay identical throughout life. Nor does it mean that grafted fat has a fixed expiration date.

How many sessions are needed?

This depends on your goals, the area, available fat, and how the first graft settles. Repeating a session to add volume or refine shape is not, by itself, a complication, but it should be discussed before treatment, including the additional recovery and cost.

For breast augmentation with fat alone, our experience is that repeat sessions are generally needed for an appreciable size increase. When fat complements another procedure, success is measured not only by breast size but by improvement in the specific area being corrected.

In the face and buttocks, a second session may refine the result. This is not decided on the basis of early swelling: we assess it once the retained volume can be distinguished. Timing is individualized, particularly when several procedures have been combined.

Aftercare and recovery: two areas need attention

Swelling, bruising, and discomfort can occur where fat is harvested and where it is grafted. The extent of liposuction and associated surgery matter greatly: a small facial correction does not involve the same recovery as buttock fat transfer or a breast lift with grafting.

Walking and gradually resuming activities are part of follow-up, but strenuous exercise requires instructions specific to each operation. Do not massage the graft or use compression garments or cushions on your own initiative. Lymphatic drainage of liposuction areas and graft care are not the same thing.

Results are assessed over the following months, not when you return to work. Follow-up checks both sites and allows instructions to be adapted to your progress.

What are the risks of fat transfer?

Using your own fat avoids an implant for that filling, but it does not avoid surgical complications. Risks include infection, bleeding, adverse reactions to anesthesia, seroma—fluid accumulation—irregularities, asymmetry, partial reabsorption, oil cysts, and fat necrosis—loss of viability in some grafted tissue.

Patient selection, experience, planning, technique, and follow-up help reduce risks but do not eliminate them. Consent should explain the risks of the specific treatment area and any combined procedures.
