Your Complete Guide to Fat Transfer

When you describe the concept of fat transfer procedures to patients, their faces tend to light up. “You can take fat from an area where I don’t want it and then put it where it will make me look better?” Fat transfer can offer the best of both worlds for the right patients. Even though the technique has only recently gained a lot of attention, I’ve been using fat transfer at my Los Angeles plastic surgery practice for years in a variety of ways.

Fat transfer—which is also called fat grafting or lipofilling—is a technique used to add volume to the face, breasts, buttocks, and hands. It’s a safe procedure that produces results that both look and feel natural.

A Brief History of Fat Grafting

The first documented use of fat grafting dates back to 1893, but it wasn’t until the second half of the 20th Century that plastic surgeons began developing more advanced techniques for the procedure. The most common use for fat grafting initially was for reconstructive procedures. It was in the early 2000s, however, when many more surgeons began using fat grafting for purely cosmetic reasons, including large-volume fat transfer.

Over the last 2 decades, the 3-step process used during fat transfer procedures has been refined to enhance the long-term results.

What Is the Process Used for Fat Transfer?

Transferring fat from one area of the body to another involves 3 distinct steps:

Harvesting: Excess fat is removed from areas such as the abdomen, thighs, or buttocks using liposuction. I use power-assisted liposuction (PAL) because it’s gentler than manual liposuction, which requires a surgeon to vigorously move the cannula (a thin tube) to break up the fatty tissue. Successful fat transfer procedures require as many fat cells as possible to remain viable during the grafting process. That’s why liposuction that uses thermal energy, such as radiofrequency or laser-assisted liposuction, isn’t appropriate for these procedures because they liquefy the cells.

Processing: When fatty tissue is removed using liposuction, it is mixed with blood and other impurities that need to be separated (much like oil from water). To do this, surgeons spin the tissue in a sterile centrifuge. The prepared fat is then placed in small, special syringes.

Injecting: Surgeons meticulously inject the prepared fat using a small cannula or needle, making multiple injections for areas such as the buttocks or breasts. When I perform fat transfer procedures, I carefully thread a line of fatty tissue in the natural tissue planes and repeat the process until there is a grid of grafted fat. It’s important that fat is layered in smooth contours so that the results look natural. Because not all the grafted fat survives the transfer process, surgeons initially inject more than is needed to create the desired outcomes.

Where Can Fat Transfer Add Volume?

Fat transfer’s versatility is one of the benefits of the technique. It’s commonly used to add volume to the face, buttocks, breasts, and hands.

  • Face: Autologous fat transfer (meaning using fat from the patient’s own body) is often seen as an effective alternative—or supplement—to facial fillers. Fat can be used for lip augmentation or to minimize the appearance of wrinkles and fine lines. Additionally, undereye fat transfer is an option for patients with hollowed-out tear troughs. Fat transfer to the face is often combined with facial plastic surgery procedures.  
  • Buttocks: Fat grafting is the technique used for Brazilian butt lift procedures—which actually augment, rather than lift, the buttocks, as you can see in these before-and-after photos. Even though some patients may choose to have synthetic implants used for buttock augmentation, the Brazilian butt lift is much more common these days.
  • Breasts: As I noted earlier, some of the earliest uses of fat grafting were for reconstructive breast procedures. In the last decade or so, however, surgeons have offered fat transfer breast augmentation for women who want only a modest increase in the size of their breasts. The technique can typically only increase breast size by about 1 or 2 bra cup sizes at most. Hybrid breast augmentation combines fat transfer with breast implants to produce a greater size increase with the more natural look and feel of fat. Browse my gallery of before-and-after photos to get a sense of the changes possible with fat transfer breast augmentation.
  • Hands: One of the areas that people often overlook when it comes to signs of aging is their hands. Aging hands lose volume just like the face, and wrinkles develop. Injecting fat into the hands results in smoother, more youthful-looking skin.

Fat transfer can add volume and improve your body contours.

Are You a Good Candidate for Fat Transfer?

The primary consideration when assessing if someone is a good fat transfer patient is that she or he has enough excess fat. People who exercise often, for example, may have too low a percentage of body fat to benefit from a fat grafting procedure. People who smoke are also not good candidates for this procedure.

Patients considering fat transfer breast augmentation who want to increase the size of their breasts by more than a cup size will probably need to combine fat with breast implants.

What Are the Pros and Cons of Fat Transfer?

There are a number of benefits associated with fat transfer, but also some limitations.

The pros include:

  • Using fat from your own body naturally augments the treatment area instead of injecting synthetic fillers or using breast implants.  
  • Results last a long time, unlike fillers which last at most for 18 months to 2 years.
  • Liposuction enhances the results of breast or buttock augmentation to create even more attractive contours.

The cons include:

  • Because it involves liposuction, a fat transfer procedure costs more.
  • When used for facial rejuvenation, fat transfer is more time-consuming than dermal fillers, which are prepackaged.
  • The percentage of fat that “takes” isn’t predictable, so patients may need multiple sessions to achieve their desired breast or buttock size.
