What is a Fatt İnjection?

It is the injection of fat into different parts of the face and body to ensure fullness. The sagging areas on the cheeks, forehead, cheek lip line, lips, tip of the chin, hips, and legs can be considered examples of the places where this application is performed.

Where do you get the fat for the injection from?

Fats are usually extracted from the abdomen using special liposuction injectors. Waist and hip areas are also often areas for fat removal. Fats from the arms and legs of those scheduled for liposuction, and even the fats from the bags under the eyes of those with eyelid aesthetics, can also be used for fat injection.

How is the fat injection performed?

The fat injection is usually performed under local anesthesia, but sometimes the fat injection can also be performed during a surgical procedure, such as filling the cheeks with a fat injection during the facelift procedure. The extracted fats are transferred to a suitable injector and the one to be transferred The area injected after performing some special processes (washing, centrifugation, 9 and since no incision is made in these procedures, no scars are left behind).

Does fat injection leave permanent fullness?

The more fat cells that are transferred to your new location, the more permanent the fat injection. Thanks to some newly developed devices, the extracted fats can be transferred to the appropriate area without contact with air. In this way, since the tissue loss is lower, the shelf life is also increased the fat injection is prolonged.

This is why fat injection is superior to fillers containing hyaluronic acid, and the rate at which fat cells remain viable depends on the surgical material used, the way the fat is removed and administered, and the transfer of the fat through various methods.

An average of 40% of transferred fats can persist for 6 months, so in some cases the fat injection may need to be repeated. In inactive areas, the chances of success are higher. For example, while fat injection in the cheek area is more successful, it can be more successful in moving areas such as the Legs will be less successful.

In which areas are fat injections most often given?

Fat injection is most commonly used on the face.
Fat can be injected to add volume to the lips, fill in deep wrinkles, fill the cheekbones, and even enlarge the lower jaw a little.

The fat injection can even be carried out before the subsequent surgical procedure for sampling purposes. For example, the results that can be achieved with a fat injection in patients with very indistinct cheekbones can be seen beforehand. If the result is satisfactory, as the fats melt briefly after a while, an implant is applied to the area as a permanent solution to achieve the same fullness.

Fats are often used to correct the shape of the hips and to correct previously performed and sagging liposuction deformities, and depressions that can occur after accidents can be successfully filled with fat injections.

Breast augmentation with a fat injection

In selected cases, fat injection can be used for breast enlargement. Fat injection gives very good results, especially in women who do not want a large breast, if there are enough resources in the waist or stomach. It offers a very natural look. If after a year another session is done, the result will be much better.

How long does it take to perform a fat injection?

The fat injection takes about 30-60 minutes. Although this method is performed under local anesthesia, it is advantageous to perform the injection in an operating room, so the use of sedatives can increase patient comfort. Although this is a simple method, the environment must be completely sterile .

Can fat cells be stored in the body?

Any remaining fats from the fat injection can be stored in sterile tubes in a suitable cooling environment. These fats can be re-injected later. Many patients prefer this method, as it is not necessary to remove fat again. However, as a doctor, I am not for that reusing the stored fats, but I prefer the injection of freshly extracted fat, in my opinion such procedures decrease the success of the fat injection and increase the likelihood of infection.

What do I have to look out for before the fat injection?

Blood thinners such as aspirin should be stopped 10 days before the procedure. In addition, the patient should inform the doctor before taking the anamnesis whether and which medication is regularly taken.

How long does the patient stay in the hospital?

The fat injection is performed under general anesthesia, but the patient can leave the hospital on the same day.

What should be considered after the procedure?

Once the fat injection process is over, a cold application is started to reduce the swelling in the injection area. The cold application is done with the help of cold gel compresses. These cold compresses are applied to the injection area for 15 minutes every hour.


In the first two days after the procedure, swelling in the area of ​​application beyond the amount of fat injected is expected. This swelling will decrease over time. However, lip area injections may take a little longer and the swelling can sometimes be excessive can be washed and moisturizing cream applied the next day after the procedure; a light massage 4-5 days after the procedure will help reduce the swelling

Fat injection does not cause discomfort that affects the person’s daily life in general, except for the first few days. The first two days should be taken more rest because of excessive edema and bruising that may appear in some areas.

Small patches at the entry points of the fat injection can be removed a few hours after the procedure or the next day, the use of antibiotics is recommended for preventive purposes, the antibiotic should be taken for 5 days.

In the first phase after the procedure, the image of the face or the injection area is not only formed by the given fat, it is normal for edema to develop in this area when surgery is performed. This edema should not be done with the fat injection The edema resolves in the first few days after the procedure and disappears in a short time.

What problems can I have with a fat injection?

  • Although the chances of infection are reduced, as with any other procedure, fat injection can develop infection. The signs of infection include redness in the area to be treated, increased pain, and increase in body temperature. The infection should be treated with appropriate antibiotics.
  • Some of the fat melts after a certain time, so that the fullness is lost. Then the process can be repeated. Since the fats are distributed homogeneously, the melting of the fats is also homogeneous. Asymmetry is very rare.
  • Tnumbness or excessive sensitivity in the area of ​​application are problems that occur very rarely, in such a situation the area can be treated with light massages.
  • In the case of very superficial oil injections, there may be a color change in the process area. This situation is extremely difficult to correct. For this reason, repeated injections and very close to the surface should be avoided.
  • While it is extremely rare for excessive fat to be administered and the fat cannot be properly injected, the fat may turn into tangible masses. This situation is more common in areas where the skin is very thin, e.g. The treatment of such a fat mass is to massage the area and use drugs that reduce tissue edema.
