The first step for this procedure is to collect fat from donor sites on other parts of the body. Liposuction is the initial step, which may be done under local or general anesthesia. After the collection of fat from the predetermined area, it is processed and purified. This output is re-injected into the face. However, this treatment is not only for the face but also for other parts of the body such as the breasts or buttocks. Do not panic if you think that your face has been overfilled with re-injected fat. This is a standard operating procedure because the body absorbs some of the fat that was injected. This procedure requires a longer downtime than those, which use synthetic fillers. You will need around two weeks off from work since your face and the donor site will be swollen and bruised and there may also be small hemorrhages.

FAT TRANSFER COMPLICATIONS

Although fat grafting has been around for more than a century and has been commonly used in the last 30 years, there are still complications that you have to watch out for. One is the growth of warts on the cannula entry areas. The only way to treat this is through cauterization. Another very extreme recorded consequence of this procedure is blindness. It will take place if the injection is pointed towards the eyeball rather than around the orbit. This is not a result of the procedure per se but if it is not done with caution, this could be the result. There is also the usual possibility of infection, which is commonly caused by unsanitary instruments used in the procedure. Allergic response more often than not is out of the question since the filling is taken from your own body. There are also instances where patients have developed cysts caused by the coming together of necrotic fat cells or simply because of overfilling of fats in a certain area after the procedure, but this can be treated by post-procedure compression. 

Having said all this, fat grafting is still the procedure advised by most doctors because it is the least dangerous.
