Hip-Up – Buttocks Augmentation/Lift


Fat has some interesting properties. If it is injected into muscles or bones, it feels like muscles or bones once it’s under the skin. Likewise, if fat is injected into a more corpulent area it feels like, well, fat. The down side of transferring fat to the buttocks, face, lips or any other place in the body, is that some of it will be reabsorbed by the body. And often, surgeons can’t really predict how much will be reabsorbed. What we can say is : what you have remaining after three months will be yours permanently.




One of the best ways I’ve found for making fat cells remain in new sites in the body is to place pearl-size drops in different layers of the muscles and fat – starting with the deepest — where they will be close to a blood supply. That’s what will make the transferred fat survive. The layering method will create a smooth, more rounded buttock with no irregular places showing through the skin.

Just after the procedure, the buttocks will swell somewhat and then subside. Thus, most patients think all the transferred fat has gone away but actually, it was the swelling that went down. That’s why it requires three months before we can get a final resolution on how much fat actually remains.




Of course, every case is different, but the amount of fat required for each buttock is an average of about 250 to 350cc of pure fat. So, for both sides, that equals about 700cc which is about ½ to about ¾ of a pound of fat. Most people are very pleased to have that amount of fat removed from their bodies; however, if you are very thin and carry very little body fat, you may be best served by having an implant inserted into each of your buttocks. However, if you can spare the fat, then fat transfer is the best option.

And remember, it is not always a matter of how much fat is contained in one area but where the fat is located that actually decides what the shape of buttocks will be. I just about always suggest some form of gluteal augmentation with fat to most patients who are interested in having their buttocks shaped and contoured.

You may find some myths about fat while you are researching the procedure. One of the most widespread is that fat transfer will result in a lumpy or bumpy surface. Another myth is that fat transfer will create cellulite. Just the opposite is true—fat is frequently used to correct irregularities and deformities in the skin. So after fat transfer into your buttocks, your skin and rear will feel very natural and appear like it is your own – which it is because the fat has incorporated into your body.

Most patients want to know right at first how long it takes to recover from a fat transfer into the buttocks. Our yardstick for that is the length of time it takes for you to recuperate from the liposuctioned areas. The liposuction incisions are very small, just enough to allow the suction wand, or cannula, to go under the skin and take out the fat that we work with. However, your buttocks won’t feel any discomfort at all. After the procedure, you must wear a body garment for 6-8 weeks. You can go back to work after about 7-10 days faster if you feel ok.




The procedure is fairly straightforward and involves placing a single scar under the butt that, after healing, becomes so well hidden, not even your closest intimate will be able to find it.

Many patients ask if an implant can leak. Breast implants which are filled with saline or silicone can leak but the implants used to augment and shape the buttocks are made of solid silicon which can not break and leak any fluid into your body.

Patients are also quick to ask what the implant feels like after healing. The augmented rear end has a firm but natural feel, about like the feel of a person has who been working out with weights or exercising hard for many years. Moreover, you actually do not sit on the implant because it is placed somewhat higher than the bones on which you actually sit.

The actual surgical procedure can be done under a general anesthetic, a spinal, IV sedation or an epidural block.




When evaluating the shape of the buttock, we divide its anatomy into three sections ; the upper buttock, the mid buttock and the lower buttock. Each area needs to be evaluated and addressed separately to provide the best gluteal harmony.

When a gluteal enhancement is done, the implant is mainly augmenting the upper buttock and the upper portion of the mid buttock. It will not fill out the other areas. In the majority of patients, a careful analysis of the middle and lower buttock needs to be made since complimentary procedures may be required in order to improve the overall shape.




The operation involves placing an implant that is made of silicone (either cohesive silicone gel or solid silicone) in the buttock to improve size, shape and contour.
