Fat Injection procedure involves extracting excess fat cells from the patient’s abdomen, thighs, hips or elsewhere, and re-injecting them beneath the facial skin, lips, breast, buttock or anywhere else as required. The time of the fat injections varies from patient to patient. Normally, 50-60 % of the fat stay for around 5 – 6 years.

Often fat is most used to fill in “sunken” cheeks or laugh lines between the nose and mouth, to correct skin depressions or indentations, to minimize forehead wrinkles and to enhance the lips, for peri-orbital rejuvenation, and treat depressed scars, acne scars, and others.


Consultation with Doctor

After both the donor and the recipient sites are cleansed and treated with local anaesthesia, the fat is withdrawn using a syringe with a needle or a cannula (the same instrument used in liposuction) attached to a suction device. The fat is then prepared and injected into the recipient site with a needle. Sometimes an additional bandage is applied over the injection site. “Overfilling” is necessary to allow for fat absorption in the weeks post-treatment.

When fat is used to fill sunken cheeks or to correct areas on the face, other than lines, this overcorrection may make face look abnormally puffed or swollen.


The swelling and puffiness may last several days, especially, if a large area was filled. While some patients are able to resume their activity immediately post-treatment, some may be advised to curtail them for a brief time. One can expect some swelling, bruising or redness in both the donor and recipient sites. The severity of these symptoms depends upon the size and location of the treated area. One should stay out of the sun until the redness and bruising subside – and it usually takes about 48 hours.
