Fat grafting
What Is Fat Grafting?
Fat grafting, also known as autologous fat transfer, lipofilling, or fat injection, is a procedure in which a surgeon removes fat from one area of the body through liposuction and injects it into another area to add volume or improve contour. Because the fat comes from the patient’s own body, it’s generally well tolerated and avoids the use of synthetic implant material.1
Fat grafting is used in a wide range of applications, including breast augmentation and reconstruction, buttock augmentation, facial rejuvenation, and refining the results of body contouring procedures such as liposuction.1,2
The majority of reported complications from fat grafting are of low morbidity, and the procedure has a good long term safety profile.

Who Is a Candidate for Fat Grafting?
Good candidates are generally in good overall health, do not smoke, and are able to maintain a stable weight, since drastic weight changes after the procedure can affect the survival and appearance of the transferred fat.1
Patients need an adequate donor site with enough fat to harvest, since more fat must be removed than will ultimately be used, as a portion of transferred fat cells do not survive the process. This means people with very little body fat may not be ideal candidates for fat grafting.1
Common Applications
Fat grafting can be used to add volume to the breasts as an alternative or complement to implants, restore contour after a lumpectomy or other breast surgery, enhance the buttocks in a procedure often called a Brazilian butt lift, and refine facial contours by restoring volume to the cheeks, temples, or under eye area.2,3
It’s also frequently used to smooth irregularities following liposuction or other body contouring procedures, since fat grafting allows a surgeon to precisely add small amounts of volume exactly where needed.
The Procedure
Fat grafting is typically performed in three stages. First, fat is harvested from a donor area, such as the abdomen, thighs, or flanks, using liposuction. The harvested fat is then processed, or conditioned, to separate viable fat cells from blood, fluid, and damaged cells. Finally, the purified fat is carefully injected into the target area in small amounts, often through multiple passes, to maximize the fat’s blood supply and chances of survival.1
Depending on the treatment area and extent of correction, the procedure can be performed under local anesthesia with sedation or general anesthesia, and typically takes one to several hours.
Recovery
Recovery involves healing at both the donor site, where liposuction was performed, and the area where fat was injected. Swelling and bruising are common at both locations and can take up to several weeks to fully subside.1
Some patients return to work and normal activities within about a week, while others need two weeks or more, depending on the extent of the procedure and how much fat was transferred.1
Risks and Complications
Bruising and swelling are expected following both the fat harvesting and injection steps. Because a portion of transferred fat cells do not survive, the treated area may lose some volume over the following months before results stabilize, and if a significant portion of fat does not survive, it can lead to fat necrosis, firm or lumpy areas, or the formation of oil cysts at the injection site.1
When fat grafting is used in breast procedures, available evidence has not shown that it increases the risk of breast cancer, though long term monitoring and follow up imaging remain important given the relatively newer widespread use of the technique in this area.4
Results
Results become more apparent as initial swelling resolves, typically over several weeks, though the fat continues to settle over the following months as some volume is naturally reabsorbed by the body. Once the surviving fat stabilizes, results are generally considered long lasting, behaving like the patient’s own natural tissue since it is, in fact, living fat cells.1
Why visual communication matters for fat grafting?
Because fat grafting involves three distinct stages, harvesting, processing, and reinjection, patients often find it difficult to understand exactly how their own fat is transformed from one area of the body into another, or why some of the transferred volume is expected to be reabsorbed.
Medical illustrations and animations can walk patients through each stage of the process, show how fat cell survival relates to injection technique, and help set realistic expectations about how results evolve over the months following treatment.3
Visual communication can support:
- Step by step fat harvesting, processing, and reinjection animation
- Comparison of fat grafting with implant based procedures
- Facial and body anatomy education for specific treatment areas
- Fat cell survival and volume retention education
- Patient informed consent resources
- Surgical training for medical professionals
- Marketing and patient education materials for plastic surgery practices

Frequently Asked Questions
Where does the fat come from in fat grafting?
Fat is harvested from a donor area on the patient’s own body, commonly the abdomen, thighs, or flanks, using liposuction.1
How much of the transferred fat survives?
A portion of transferred fat cells naturally do not survive the process, so the treated area may lose some volume in the months following the procedure before results stabilize. Surgeons typically transfer more fat than the final desired amount to account for this.1
Is fat grafting safe for breast procedures?
Available evidence has not shown that fat grafting increases the risk of breast cancer when used for breast augmentation or reconstruction, though long term monitoring remains an important part of care.4
How long does recovery take after fat grafting?
Recovery varies, but many patients return to normal activities within about a week, while others need two weeks or more, since healing occurs at both the donor site and the treated area.1
What happens if the fat doesn’t survive properly?
If a significant portion of transferred fat doesn’t survive, it can lead to firm or lumpy areas, known as fat necrosis, or the formation of oil cysts, which may require additional treatment.1
What areas of the body can be treated with fat grafting?
Common treatment areas include the breasts, buttocks, face, cheeks, under eye area, and lips, with fat also used to smooth irregularities after liposuction or other body contouring procedures.2,3
