The fat used for fat transfer can be extracted from any part of your body like the abdomen or thighs by liposuction, and it will be injected where needed. This cosmetic procedure can be used to rejuvenate the face, augment the cheeks or lips, or correct problems such as hollowness around the eyes or scars.
Fat grafting is usually performed under local anesthesia.
Liposuction—The fat used to re-inject in the face can be taken through means of a liposuction from any part of the body having a sufficient amount of fat, in most cases from the abdomen or the upper legs. After injecting local anesthesia, which minimizes bleeding in this particular area, a very small incision is made and fat is aspirated using a blunt needle with multiple perforations and a special aspirator.
Filtration—This fat is filtered to separate blood, oil and local anesthetic from the fat cells.
Fat injection—The place where we want more volume is injected with a minimal amount of local anesthesia after which the fat cells are injected with very fine canulas.
The trick of the fat transfer is to inject only a very small amount of fat with each pass of the canula. This way the grafted fat will be in direct contact with the surrounding tissues and will make it possible for the fat to grow in the vessels really fast. Thus the fat can survive.
