The fat graft...
Injection of fat tissue
The fat graft, also known as fat injection, is a procedure that consists of using liposuction to remove a quantity of fat tissue from a specific body location (donor site) and injecting it into a receiver site. This technique is an alternative to reabsorbing injections. The fat tissue injection causes neither allergy, nor rejection since it consists of the person's own fat tissue. Studies show that 20% to 30 % of the fat cells injected at the desired place will survive permanently.
The donor site is usually on the thighs or abdomen. The fat tissue taken is then injected into the receiver site. Facial areas that respond best to fat grafts are: lips, the nasal folds frown lines and labial junctions (laugh lines).
The procedure is performed in an operating room, under local anaesthesia with or without sedation. Occasionally, one or two additional injections are necessary to reach the desired aesthetic result. Smoking tobacco and drinking alcohol can decrease the lifespan of injected fat cells.
