Butt augmentation with fat: How long do the results last?

Butt augmentation with fat: How long do the results last?

23rd Nov 2020


Butt augmentation with fat is a plastic surgery procedure that beautifully sculpts and enhances the buttocks by using your body fat. Unlike butt implant surgery, this procedure does not involve the use of external objects like gluteal implants. Also called fat transfer to the butt and Brazilian butt lift, this surgery is suitable for patients who want to get a curvaceous body with shapelier buttocks that are also mildly projected. It is one of the most common and popular plastic surgery procedures in the US. 

If you want to undergo butt augmentation with fat, you may be wondering as to whether the results of the surgery are permanent or how long the results last. This is an important question, and you must discuss it with your surgeon during the initial consultation. I will answer this question in detail in this article. 

What is butt augmentation with fat?

Patients often find it difficult to understand the answer about the longevity of the results of fat transfer surgery without knowing the details of the operation. It is essential to first get acquainted with the surgery and know what it involves. Butt augmentation with fat does not augment the butt considerably. Instead, it is focused on making the butt shapelier and adding some projection to them. To qualify, you need to have excess, unwanted body fat that can be used as donor fat for enhancing your backside. 

Fat transfer surgery involves three critical steps: fat extraction, fat processing, and fat grafting. In the first step, the plastic surgeon will perform liposuction on the fat donor areas to extract the excess fat. The typical fat donor areas include the sides, love handles, abdomen, and upper back. Now, two goals are achieved with liposuction of these areas. First, donor fat is collected for transfer to the butt and second, these areas in the vicinity of the butt are contoured and reduced, which makes the butt look prominent and shapelier. It also helps make your body curvaceous.

In the second step, the plastic surgeon will process the fat for purification purposes. It is done by spinning the fat in a centrifuge at high speed. During this step, the impurities, dead and damaged fat cells, and fluids are removed from the fat collection. It is vital for the sustainability of the results of fat transfer surgery. Only healthy and alive fat cells are retained for transfer to the buttocks. 

In the last step, the purified fat cells have to be injected into the buttocks. The plastic surgeon will use a special needle to implement this step. He will carefully pick the fat cells with a needle and then inject them into specific areas of the buttocks that would help enhance the butt. It is one of the most critical steps of the surgery and needs to be executed with extreme care. This step is time-consuming and involves a lot of work and contouring. If your surgeon is skilled and experienced and has the required artistry and sense of aesthetics, he will beautifully carve your butt into the desired shape during the fat grafting.

The results of fat grafting will gradually emerge over the next few weeks and months following the operation. 

How long do the results last?

Now that you know how butt augmentation with fat is performed, you can have a better idea about the sustainability of the results. Keep in mind that the results will not be immediately visible. Instead, they will evolve. Typically, it can take many weeks and even months for the final results to emerge. Even though you may see some improvements in the fat donor sites right after the procedure, you will have to wait to see the final results. The fat injected into your butt needs to be vascularized. 

The patient has to go through a recovery process that can take many weeks. As your body recovers, your waist will decrease in size, and the fat donor areas like the flanks, abdomen, and upper back will look smooth and beautifully contoured. It can take your body about two weeks to establish blood supply to the fat cells that were injected into your buttocks. Once that happens, the fat cells will start to grow and deliver the results gradually. After six weeks or up to two months, your buttocks will appear projected, shapelier, youthful, perky, and sexy. As a result of these improvements, you will look more feminine and younger. 

How long the results of butt augmentation with fat lasts depend on many factors.  But one thing is for sure: even though the results may stay with you for several years and even decades, they are not permanent. As you age and your body experiences hormonal and physical changes, your butt shape and projection will change accordingly. 

The first thing to keep in mind is that your body will reabsorb some portion of the fat injected into your buttocks within the first few weeks and months. What this means is that the projection achieved in the initial weeks is not final. You may lose some of the projection afterward.

Secondly, the sustainability of the results largely depends on how the surgery has been performed. The crucial steps of the operation are fat removal, fat purification, and fat grafting. If your plastic surgeon is inexperienced and fails to perform these steps correctly, the results may not stay with you for long. For example, if dead and damaged fat cells are injected into the butt, the results will fail to transpire or will be reversed after a few days or weeks. 

Next, the longevity of the achieved results also depends on post-operative care. Pressure and strain applied to the buttocks during the first six weeks following the operation can kill the fat grafts, which will make the results unsustainable. You must avoid sitting and sleeping on your back for two weeks after the surgery and avoid physically strenuous activities for six weeks after the procedure. 

Another dominant factor that can affect the results of butt augmentation with fat is your weight. Massive weight loss any time after the surgery will shrink your butt and reverse the results. The fat injected into your butt comes from your body and behaves the same way as the fat in other areas of the body. Weight loss will lead to shrinkage or even liquidation of the fat in your buttocks, which will lead to the results being reversed.  For this reason, patients are always advised to avoid massive weight loss after fat transfer surgery.

Furthermore, massive weight gain after the surgery will affect the fat donor areas, though it may expand the fat cells in your butt. Keep in mind that the fat donor areas were contoured during the surgery in such a way that it makes your body look curvaceous and your butt prominent. But when you experience weight gain, it can trigger the development of stubborn fat pockets in the areas that were previously treated by liposuction. As a result, the results achieved with liposuction will vanish, and the target areas will become bulky, poorly contoured, and aesthetically unwelcoming.

So, your weight after butt augmentation with fat is the most powerful factor that determines the longevity of the results of fat transfer surgery. You must stick to a balanced and healthy diet and avoid considerable weight changes so that the results can stay with you long-term. Make sure to avoid junk and fatty foods after the surgery and instead include vegetables, fruits, vitamins, minerals, protein, and other essential nutrients in your diet. Doing so will keep your weight stable and prevent changes to the achieved results. 

To make the results last longer, be sure to choose the plastic surgeon carefully and follow his instructions. Also, make sure to wear the compression garments for the recommended time, avoid massive weight changes, avoid activities that can apply pressure to the butt for six weeks after the surgery, and stick to a healthy and balanced diet. 


Butt augmentation with fat is a modern and major plastic surgery procedure that beautifully sculpts the booty and other localized areas of the body. During the surgery, the stubborn fat pockets are removed from the body areas like the abdomen, sides, and flanks and then injected into the butt. As a result, the buttocks become prominent, and the fat donor areas become contoured. Many patients ask whether the results are sustainable and how long they last. In this article, I have answered this question. I have also discussed the factors that affect the sustainability of the results and what you can do to prolong them.
