Micro Fat Grafting


Micro fat grafting is a method of adding fullness to an area of the body that has lost volume. As people age, their skin become thinner. The loss of fat is particularly apparent on the face and hands. Fat grafting is a way of restoring fat to the skin to regain a full, youthful appearance.

Fat transfer, or fat grafting, is a process during which fat is taken from a fatty area of the body and injected into another body part. Fat is harvested from the abdomen or hips using a liposuction technique, though very little fat is removed. This fat is processed to remove fluids. The fat is then injected into the desired area. The procedure is called micro fat grafting because tiny amounts of fat are injected throughout the desired area. Depositing numerous, small quantities of fat enables optimum blood flow to the new fat. It will assimilate into its new location more quickly.

Micro fat grafting is popular for facial rejuvenation. Fat is used to fill in cheeks, laugh lines, and around the eyes. Many patients are opting for autologous fat grafting, which means the fat comes from the patient’s own body. The benefits of autologous fat grafting are: there is no risk of an allergic reaction and it is generally less expensive than synthetic fillers. Many patients are simply more comfortable having their own fat relocated versus injecting a filler.

Micro fat grafting can be done to other parts of the body as well. Fat grafting is performed to add fullness to the buttocks, for example. In a study published in the Aesthetic Surgery Journal, the authors noted that micro fat grafting is a safe way of adding size to the buttocks. Of 566 cases, 50-75% of the fat grafted remained long term. Compare these results to implants, which can cause significant scarring. Micro fat grafting is performed with numerous micro injections. There are no scars and no foreign materials in the body.

Breast augmentation can also be achieved with micro fat grafting. Fat added to the breast can create natural-looking enhancement without implants. It is an option for women who want a subtle increase in size. Fat grafting can be used following breast implants to make them look more natural, especially in very thin women. Fat grafting of the breasts can also be used to improve the appearance of reconstructed breasts.

The results of micro fat grafting may not be permanent. Some of the fat will be absorbed by the body. The longevity of the remaining fat varies with each patient and is dependent upon where the fat was injected.
