Microlipoinjection , also called autologous fat transfer, is a procedure in which an individual’s own body fat is used to plump up sunken or emaciated areas of the face or to add volume where desired. The word “autologous” simply refers to the use of one’s own tissues or fat. Because the patient’s own fat is used, autologous fat transfer requires three steps. The first step involves the gentle liposuction of some excess fat (such as that found in the jowls, abdomen, thighs, or buttocks). The second step involves the isolation and cleansing of the fat cells. The third and final step involves the injection of the fat cells into the targeted facial areas
Facial fat injections can eliminate aspects of facial “wear and tear” that often appear with age, such as smile lines, frown lines, marionette lines (running from the sides of the mouth down to the chin), wrinkles and furrows, and hollows in the face (such as under the eyes or under the cheekbones). Lips that have lost volume may also be treated through fat transfer as can scars or depressions in the face from scars (such as those from acne). Individuals with one or more of these conditions may be good candidates for autologous fat transfer.
Ideal Fat Transfer Candidates
In general, candidates for fat transfer are adults who would like to diminish or eliminate the appearance of wrinkles, creases, furrows, smile lines or frown lines, marionette lines, or depressions in the face. Fat injection may also be used for lip augmentation. Younger patients may be eligible for fat transfer in some cases.
A fat transfer via injection is also often used in patients who have experienced lipoatrophy, which is loss of the layer of fat in the face that forms the contours of the cheeks and jawline. A fat transfer can fill in the hollow areas and restore pleasing contours to the face.
The safety of the autologous fat transfer technique ensures that there are no restrictions associated with allergies. However, at your first appointment, you should be sure to disclose all of your medical history and current habits such as smoking and use of blood-thinners, medications, birth control pills, or supplements, so that your dermatologist or cosmetic surgeon can accurately determine whether you’re a good candidate for fat transfer.
What Areas of the Face Can Be Treated with Fat Injections?
The facial areas that can be improved with fat injection treatment include creases in the forehead or in between the eyebrows, and hollows under the eyes. Fat injection can also plump up or improve the contour around the nose, the area between the upper lip and the nose, the jawline, and the temples. Indeed, fat transfer can correct scars, sunken or hollow areas, and any place on the face or neck where fat has been lost.
Some of these facial areas need only one fat injection for noticeable and long-lasting improvement, whereas others will require more than one fat transfer to be adequately corrected.
