It has been experienced for years that fat injection applications give aesthetically satisfying results. However, in some patients, the rate of persistence of these results has not been satisfactory.

Nowadays, thanks to the developing technology, the excess fat removed from your body is enriched with your stem cells which have been isolated from that fat and injected to another region requiring treatment, which has increased the persistence of the results to a great extent.

How is fat injection with stem cell technology performed?

In the past, it was believed that the highest amount of stem cells can be obtained bone marrow. It is now known that the amount of stem cells in fat is 4 times greater than that in bone marrow. In this way, rich stem cells isolated from fat are used during injection.
Part of the fat taken from the person by liposuction method is sent to a special stem cell laboratory for isolation of stem cells from the fat, which are then injected into the areas where fat injection has been applied.

Another option is to mix the stem cell obtained during the operation with the patient's fat and apply fat injection to the area requiring treatment.

It was seen that in fat injection applications without using stem cell technology, only 20% -30% of the fat remains in the body in 1 year, whereas in such applications with added stem cells, that ratio increases to 50%-80% depending on the region.
