Fat transfer (also called fat grafting or fat injection) is a two-step procedure that removes fat from one area of the body, usually the abdomen or thighs, via liposuction, then re-injects it into another area, such as the face, breasts, or buttocks, to add volume and a natural, youthful contour. Because it uses your own tissue, it carries no risk of allergic reaction or rejection, and most patients retain 50–80% of the transferred fat permanently.
Key Takeaways
- Fat transfer uses your own tissue, reducing rejection risk and allergic reactions compared to synthetic fillers.
- Most patients retain 50–80% of the transferred fat long-term, making it a more durable option than fillers, which require regular touch-ups.
- The procedure involves two steps: harvesting fat via liposuction and then injecting it, which can mean more downtime.
- While fat transfer has a higher initial cost, it’s often a one-time investment for larger areas, whereas fillers may need endless sessions.
- Fat transfer can also rejuvenate the face by restoring lost volume and addressing visible ageing.
Is Fat Transfer the same as fat grafting?
Fat transfer is also known as fat grafting or fat injection. It is a cosmetic procedure that relocates a patient's own fat from a "donor site" to an area that needs more volume. Common donor sites are the abdomen, flanks, and thighs. The harvested fat is purified and then injected into the target area.
It's commonly used for:
- Facial fat grafting: Restoring volume to sunken cheeks, under-eye hollows, and areas that have lost definition with age
- Breast augmentation: A natural alternative to implants
- Buttock enhancement: Often called a "fat transfer BBL" (Brazilian Butt Lift)
- Body contouring: Smoothing depressions and improving overall shape
Because most facial ageing is caused by volume loss rather than sagging alone, fat transfer is increasingly used as a facial rejuvenation treatment, not just a body-shaping one.
Fat Transfer vs. Dermal Fillers: Key Differences
Both treatments smooth wrinkles, restore facial volume, and improve contouring — but they differ in material, downtime, longevity, and cost.
| Factor | Fat Transfer | Dermal Fillers |
|---|---|---|
| Material used | Your own body fat (autologous) | Synthetic or biosynthetic substances (e.g., hyaluronic acid) |
| Allergy/rejection risk | None — it's your own tissue | Possible in patients with multiple allergies |
| Procedure time & downtime | Requires liposuction + injection; some swelling and a few days of recovery | Typically under an hour, minimal to no downtime |
| Longevity | Long-lasting; 50–80% of transferred fat is typically retained permanently | Temporary; needs repeat sessions at regular intervals |
| Upfront cost | Higher per session | Lower per session, but recurring costs add up over time |
| Best for | Larger-volume changes (breast, buttock, extensive facial volumizing), patients wanting a permanent result | Smaller touch-ups, patients wanting a quick, low-downtime option |
Grafting Uses Your Own Fat
Since fat transfer uses your body's own resources, it eliminates the risk of allergic reaction or rejection while restoring volume for a natural look. Dermal fillers, by contrast, use synthetic materials that can occasionally trigger reactions in patients with multiple allergies — always discuss your medical history with your doctor before choosing either option.
Downtime Comparison
Fillers typically involve no incisions or anaesthesia, and patients can leave the clinic within the hour. Fat transfer involves fat harvesting (liposuction) followed by injection, so some swelling and a short recovery period should be expected, though discomfort is generally minimal.
Number of Sessions
Fillers often need to be repeated at intervals depending on the product used and how the body metabolizes it. Fat transfer results are longer-lasting: most patients permanently retain 50–80% of the transferred fat.
Cost Considerations
Fillers tend to have a lower cost per session, but repeat treatments accumulate over time. Fat transfer has a higher upfront cost but is typically a one-time investment, especially for larger areas like breast or buttock augmentation.

FAQ
Is fat transfer permanent?
Most of the results are long-lasting. Studies and clinical experience show patients typically retain 50–80% of the transferred fat permanently, compared to dermal fillers, which are metabolized and need repeat sessions.
Does fat transfer hurt?
Discomfort is generally minimal, though it varies by treatment area. Because the procedure involves both liposuction (fat harvesting) and injection, expect some swelling and mild soreness for a few days afterward.
What's the difference between fat transfer and fat grafting?
Nothing, "fat transfer," "fat grafting," and "fat injection" refer to the same procedure and are used interchangeably.
Can fat transfer be used on the face?
Yes. Facial fat grafting is commonly used to restore volume lost to ageing, such as sagging cheeks, hollow under-eyes, and loss of facial definition, giving a more youthful appearance.
Is fat transfer safer than dermal fillers?
Fat transfer carries no risk of allergic reaction or rejection because it uses your own tissue. Fillers are generally very safe but use synthetic materials that can occasionally cause reactions in patients with multiple allergies.
How do I know if I'm a candidate for fat transfer?
Suitability depends on your aesthetic goals, the amount of donor fat available, and your overall health. A consultation with an MOH-accredited liposuction doctor experienced in fat grafting is the best way to find out.
