Fat transfer, also called fat grafting, fat injections and lipofilling, is a procedure that uses a person’s own fat to fill in irregularities and grooves. This is now a well-established technique that was perfected in the early nineties to a predictable procedure.
Aesthetic indications for undergoing lipofilling include sunken cheeks, the disappearance of fat from the cheekbones, deep grooves running from the nose to the corners of the mouth, and in some instances of lines between the lower eyelids and the cheek. It is also one of the most common methods used for lip enhancement. In addition, lipofilling can be used to smooth out all types of irregularities such as those resulting from poorly performed liposuction or injuries.
The necessary fat is obtained by a limited liposculpture through one or several 3 to 5 mm incisions. It is normally taken from the abdomen or inner thigh. The aspirated fat is processed by centrifuging, filtering or rinsing. Pure liquid fatty tissue ready for injection is the result.
The fat is then injected where needed. The fat is evenly distributed into the area by injecting minute amounts in the tissues so that the injected fat is well surrounded by healthy tissue. This ensures that the transplanted fat remains in contact with the surrounding tissues that must supply it with oxygen and nutrients.
About an hour, depending on the size of the areas to be treated.
