Fat Injection

Fat injection or transfer is a process in which fat is taken from one part of the body and transferred to another part of the body. The purpose of this is to improve the appearance of the target area.

In this method, the plastic surgeon first removes fat from the body by liposuction, prepares it for re-injection with a special process, and transfers it to the target area.

The popularity and prevalence of taking fat from the body and injecting it into another part started in the 1990s. Cosmetic doctors use this method to rejuvenate and beautify the chest, hands, feet, face, hips and vagina. Recently, doctors use this method to heal scars and even restore breast tissue after radiation therapy.


Fat injection process

1. Fat extraction

At this stage, the doctor first selects the extraction site according to the patient’s condition and wishes. The extraction site must have enough accumulated fat.

For this reason, the abdomen, hips and thighs are usually suitable options. Then the cosmetic doctor numbs the desired area and extracts the fat using special techniques. If the amount of fat required is greater than a certain limit, the doctor usually uses anesthesia to extract the fat.

2. Preparing fat for injection

Extracted fat is not suitable for injection and it is necessary to go through steps to prepare it. During these stages, fat is purified using a centrifuge or other methods, and dead cells and excess liquid are separated from it.

3. Fat injection to the desired area

In the last step, the doctor injects the desired amount of fat using special syringes into the desired area, which is completely numbed and sterilized. This work requires high skill and precision.


Common and suitable injection areas

Because fat is taken from the person’s own body, it is highly compatible and can be injected into most areas. Its choice depends on the conditions and wishes of the individual. In the following, we introduce common areas of the body that are suitable for fat injection.
