Fat transfer/Fat injection also Known as Brazilian Butt Lift

Platelet injection fat transfer, fat injection or fat grafting, are all medical terms for a fat transfer also know as Brazilian Butt Lift. This procedure uses the patient’s own fat tissue to mold or sculpt or increase the volume of fat in the subcutaneous areas of the body. Autologous adipose tissues transplantation is often used for breast augmentation or breast reconstruction surgery after caner. Fat transfer has several potential advantages to other injected fillers, among which are the facts that the body cannot reject its own fat and that fat transfers remain transferred. I.E, when other fillers are used, they aren’t permanent. Fat transfer procedures can be used to fill wrinkles on the face, smooth and repair aged hands, enlarge breasts or create shapelier, curvaceous buttocks. 

There has been some debate in the past over whether or not fat transfers result in any significant retention. A study published by the UCLA Division of Plastic and Reconstructive Surgery in 2007 claimed that "the literature fails to provide definitive evidence of fat survival". In other words, it appeared for a time that fat-transferred tissue was reabsorbed by the body and didn't provide any long-term results. However, a recently published study seems to have proven otherwise. The study included 85 patients and evaluated the method of water-jet assisted liposuction and autologous fat transfer for breast augmentation. A permanent take rate (or volume of gain) of 11% grafted fat after a period of six months was verified. The study assessed volume gain by pre and post-operative MRI spectroscopy. With promising results like this, fat transfer once again appears to be a legitimate and safe procedure.


Fat is withdrawn from the patient either by a syringe that has a large-bore needle or with a liposuction cannula. The fat must then be cleaned of blood, pain killers and other unwanted ingredients that could cause infections or side effects. 

Some procedures require the implantation of tiny strips of fat cells. These procedures take slightly longer but are reported to have the longest lasting effects (the method is particularly common when filling in lips or deep lines in the face). Effectiveness varies greatly form client to client depending on the surgeon, the client’s body and other factors. The body can absorb anywhere from 20% to 95% of the transferred fat. This means that the surgeon will transfer more fat than is actually wanted to compensate for that which will be reabsorbed. That said; fat transfers tend to last longer than other fillers, with results reportedly lasting for years instead of months.

This procedure is most commonly performed while the patient is under local anesthesia and light sedation and can often be done in surgical suits right in the practitioners office.

Fat Transfer Recovery

Cosmetics are discouraged in the case of face fat transfers (the most common procedure) for at least 24hrs. Regardless of the where the transfer is, keeping that area as immobile as possible is extremely important in order for the transferred fat cells to find and establish a healthy blood supply (so they don’t get reabsorbed). Mild or moderate swelling and bruising is often reported by patients who have undergone this procedure. Most of the swelling will subside within a few days but by 4 weeks all swelling should have receded. It is unpredictable how much of the fat your body will simply absorb and some patients may need follow-up treatments because of this. 

Recovery needs vary quite a bit from procedure to procedure. Someone having a buttock enhancement is likely going to need to stay off their backside for a few days, making driving impossible, sleeping on the belly paramount and walking a no-no as much as possible for 24-48hrs. Make sure that whatever procedure you’ve elected, you follow up by following your surgeon’s instructions to a T. Doing so can make or break the success of your surgery. 

Immediately following the surgery, you will need someone to drive you home and it might be wise to arrange help for the first two days post-op. As mentioned above, keeping movement of the are the procedure was performed on is paramount to maximize the results.

Risks and possible complications

The most common complications with fat grafting are aesthetic ones. There may be too little fat tissue implanted or too much. It’s possible to love the results for several weeks or months only to have it be completely reabsorbed by the body. As with all surgeries, the risk of a bad reaction to the anesthesia is present. Also there is a risk of infection, bad bruising and asymmetry. In very rare cases, a ruptured superficial blood vessel at the treatment site becomes permanent. Fat embolism is a rare and extremely serious complication that can result in stroke, cardiac arrest and/or death.

Most transferred fat results in a natural feel but it is still possible that some or all of the fat may become too firm, hard or lumpy. Cysts may also form at the site of injection. There is, of course, always the risk that you just aren’t happy with the results. Carefully selecting your surgeon will eliminate many of these concerns or, at the very least, reduce their chances of occurring.

Fat transfer has the benefit of being the most natural filler medicine has to offer and the best part is, you always have some available. It’s an option worth considering, particularly if what you are hoping for is a plastic surgery that’s minimally invasive with a success record that’s impressive.
