Fat injections can be an effective way to reduce wrinkles, reduce acne scarring, and regain a more youthful appearance. In this procedure the patient's own fat is collected (suctioned often using liposuction ) from a distant donor area and reinjected into the defect area. Fat transfer may require sedation plus local anesthesia if larger amounts of fat are to be collected. Small amounts of fat can be collected and transferred under local anesthesia.

Studies have shown that fat tends to accumulate in the center of our body (the abdomen in men, hips and buttocks for women), as we become older. In an effort to correct both of these unwanted problems, cosmetic surgeons have developed a technique called "autologous fat transplantation." The word "autologous" means that the material (the fat) is harvested from and donated to the same individual. This technique is also referred to as "microlipoinjection." Fat from unwanted areas ( abdomen, buttucks) is removed through liposuction, then this same fat can be harvested and stored or used for cosmetic purposes such as fat injections. The injected fat can be used to enhance lips, reduce wrinkles and lines and plump up the hollow appearance of cheeks and the area around the eyes. Fat transplantation works best for the naso-labial fold, the line angled between the nose and upper lip.

 
 What are some of the most common benefits of fat injections?

Fat injections can significantly reduce or eliminate wrinkles and other skin imperfections. It can also give patients a more youthful appearance by reestablishing pleasing contours. Fat is the first choice of material when injections are needed in deeper layers of tissue or larger volumes (greater than 10cc).

However, injected fat may not last as long as some other materials. The fat is slowly absorbed by the body, although the amount of absorption is variable, and frequently hard to predict. Typically, more than half of the fat used in injectable treatments is absorbed with six months of the operation. Almost all patients will permanently retain some of the injected fat. However this percentage varies from patient to patient. If a significant amount of fat is absorbed, a second procedure may be needed to completely correct the sagging, wrinkling or other skin imperfections.

 What will happen at the initial consultation?
During the consultation, you and your surgeon will discuss the changes that you would like to make in your appearance. He/she will examine your skin and facial structure, and explain the different options available to you. Once you’ve settled on an option, he/she will explain the procedure itself, its risks and limitations, the anesthesia required, surgical facility, and costs involved. Be sure to as all the questions you have about the surgery, and ask to see photos of the doctor’s recent patients, before and after surgery. Also ask for, and follow up on, patient references. Learning everything you can about your options, risks and benefits is the key to making an informed decision. See Questions to ask your doctor.

 How are fat injections performed?

A fat-injection procedure is a two-step process that may require more than one visit to the doctor. The fat must be harvested from somewhere on your own body -- typically from the abdomen or hips. This can be done in conjunction with a liposuction procedure. After it is extracted, it is placed in a centerfuge to separate the fat from surrounding tissues. The fat is then packed into a large syringe to accommodate its granular nature.

Because fat is a bit larger than other injectable materials, it is almost always injected more deeply into the skin. Volumes of up to 50-100 cc can be used to over the entire face. (Fat is the only injectable material that can be used at these larger volumes.) The injected fat plumps and tightens the skin, thereby decreasing (and in some cases eliminating) wrinkles, scars and lines from sagging skin.
