Facial fat injection:
While most people think that the most significant signs of aging are wrinkling and sagging skin, one of the major underlying causes of these problems is something else: facial volume loss. This loss of facial volume can lead to accentuation of the bony contours of the temples and around the eyes and can make the cheeks look flatter and less full. Only in the last decade has the impact of decreased facial volume on the appearance of aging become fully recognized.
Facial contour and definition are determined by genetics, which is why some people have prominent chins and cheekbones, while others have a rounder face with softer features. Whether the issue is related to aging or simply facial structure, there are ways to boost facial volume and improve the appearance of the face with facial fat transfer.
Fat transfer is often known as fat grafting, and it is a natural, minimally invasive surgical procedure to move fat from an area of the body where it is plentiful, and transferring it to the face to restore lost volume. The fat is gently removed using modern liposuction techniques, and is then prepared for injection into the face. This produces a very natural appearance, and there is little risk of infection or rejection of the fat by the body. Common treatment areas include the nasolabial folds (between the nose and the lips), marionette lines (between the lips and chin), flattened cheeks, sagging jaws, and hollows under the eyes.Facial injections are most often used to improve facial contour and volume in younger patients who would like more prominent cheekbones or chin.
Facial fillers are a non-surgical method for filling in wrinkles and hollows and introducing subtle volume to the aging face. These treatments are injectable and non-invasive, but the results are temporary. Some fillers encourage collagen production for longer-lasting results.
Facial Fat Transfer :
There are different candidacy requirements for each procedure to restore facial volume, and your individual candidacy will be assessed during your consultation. Basic requirements for cosmetic surgery are that patients should be healthy individuals with realistic expectations who could benefit from the procedure. Facial fat transfer patients must have adequate fat to harvest and should be at a stable weight before undergoing treatment.
Facial Fat injection and Procedure:
Fat injection is a fairly gentle procedure, but there are several steps to the process. First, liposuction techniques are used to remove fat from predetermined areas of the body, such as the abdomen, hips, or thighs. This is done through tiny incisions that leave almost no scarring.The fat that has been retrieved is then gently prepared for injection, using minimal manipulation. Fat is carefully injected into the lines, hollows, and depressions of the face to rejuvenate and recontour, using fine cannulas (tubes) placed through tiny incisions. The specialist may overfill the treated areas somewhat to compensate for the percentage of fat cells that will not survive.Facial injection is fairly straightforward, and involves a simple incision in a discreet area near where the fat will be placed. The fat is injected through this incision, and the specialist will ensure that the fat will not shift.
How long does autologous fat injection last?
In conclusion, autologous fat transfer to the midface has definite long-term volume augmentation results. On average, approximately 32% of the injected volume remains at 16 months. However, some variability exists in the percentage of volume that remains that may require a touch-up procedure.
Facial Fat injection Recovery :
Fat injection recovery time varies from patient to patient, but most people should arrange to take at least 7-10 days off from work and other social activities. Initial healing takes a few weeks, after which the swelling will gradually subside before the final results are apparent. Though the recovery period is fairly mild for fat transfer, patients should allow adequate time to heal properly. Patients should see final results after about six months, though improvement should start to become apparent just a few days after injection .Facial injection recovery is also a fairly mild process that requires at least a week of downtime before returning to work and other everyday activities. Exercise will be limited for several weeks, and though the results should be apparent right away, swelling will interfere with seeing the final results of the procedure at first. Swelling should start to subside gradually, and should be fully resolved by about six months following the procedure.
The benefits of fat transfer include:
- Longer lasting results
- Area of fat removal (abs or flanks) may appear slimmer
- Stem cells in fat can create growth factors for better tissue quality
- Little recovery time needed
What are the side effects of fat transfer?
Side effects to expect
- significant bruising and swelling.
- temporary numbness.
- small scars – these will fade, but will not completely disappear.
- loss of some of the fat from the injected area during the first few months.
How does fat transfer stay in place?
Commonly, patients request that fat be removed from the abdomen, flanks and thighs, but any area can be a donor site. After the fat is washed and processed, it is reinjected into a separate area for enhancement or augmentation of the tissues. After a fat transfer, the fat cells will permanently stay in their new position.
Is fat transfer good for weight loss?
While the fat transfer procedure does involve some body contouring, this aspect of the surgery is not the focus of the process. Fat transfer is not good for weight loss, as not enough fat will be removed to make enough of a difference. Surgical fat removal is best for patients at a stable weight who want to resolve stubborn pockets of fat, in order to contour the body and ensure lasting results.
What are the risks of fat transfer?
Facial fat transfer complications are generally rare, as the procedure is gentle and safe. However, as with any surgical procedure, there are small risks involved, which may include:
• Anesthesia complications
• Fat calcification
• Over or under correction (poor aesthetic result)
Be sure to go over the risks and side effects of the procedure during your consultation so you can be on the lookout for any potential complications.
What happens if you gain or lose weight after fat transfer?
The transferred fat cells will continue to live in the area in which they were injected, establishing a blood supply and behaving like any other fat cell. This means that if a significant amount of weight is gained or lost, these cells could expand or shrink, affecting the overall results of the procedure. This is why patients are encouraged to be at a stable weight before the procedure, and maintain that weight following surgery, in order to preserve results.
In recent years, cell therapy has been widely used to the skin rejuvenation . Stem cells isolated from different parts of the body have always been of interest to researchers and is found a lot in humans. ADSC has an effect on fibroblast and keratinocyte proliferation by secreting growth factors, and some research has shown that ADSC can differentiate into epithelial cells and is suitable for improving skin damage and aging.
In the study of Nilforoushzadeh et al. , 16 patients were selected for segregation and SVF transplantation from 2014 to 2015 at the age group of 38-58. And in the area of the laugh line and the lines around the mouth of the injection was done. In this study a new technique for separation of adipose tissue used and then preparation of SVF and finally ADSC in a short time has been used.
