What is a fat injection?
The fat injection is technically called autologous fat transplant or microlipoinjection. It is a procedure in which fat cells harvested from the abdomen, thighs or buttocks of the patient are reinjected to the appropriate areas, mainly beneath the skin of the face. It is mostly used to fill in cheeks or laugh lines between the nose and mouth, to correct skin depressions or scars, to minimize forehead wrinkles and to plump up lips.
What kind of a procedure is used during fat injection?
After both the donor and recipient sites are cleansed and injected with local anaesthetic, the fat is removed from the body with a large syringe or a cannula (similar to a liposuction cannula) that is connected to a vacuum device. The harvested fat is processed and reinjected to the recipient site with a syringe. Sometimes an adhesive bandage is applied over the injection site.
It is necessary to overfill considering the fat to be absorbed by the tissues in the weeks following the procedure. When this procedure is used to add fullness to the cheeks and other sites rather than wrinkles, your face may temporarily look puffy.
What should and shouldn’t I do after fat injection ?
When a large area is treated, you may need to reduce your activities for a short period of time, but still many patients return to their normal activities immediately. You can expect some swelling, bruising or redness in both the donor and recipient sites. The severity of these symptoms depends on the size and location of the treated area. You should avoid sunlight until redness and bruising go away (approximately for 48 hours). During this period, you can wear makeup to help cover your scars.
The swelling in the recipient site may last several weeks, particularly when a large area was filled.
