Hi, I have performed many facial shaping procedures using dermal fillers, facial implants (cheek, chin), liposuction and/or facelifts for over 30 years. One day following fat injections, it would be difficult to tell how long the swelling will last. Placing fat in the lips and face causes swelling proportional to the amount injected, so this is something that your Surgeon should address. I have performed many facial shaping procedures using dermal fillers, facial implants (cheek, chin), liposuction and/or facelifts for over 30 years. In my experience and despite its recent increase in popularity, fat transfer (fat injection) offers "far" less of a reliable and predictable volume for facial shaping than an off the shelf dermal filler or silastic facial implant. For that reason, I do not use fat to shape the cheeks, chin, lips or jaw line. Tissue physiology is quite simple. Tissue requires a blood supply in and out as well as lymphatic connections to remain viable and alive. Once fat is removed from the body all of these things have been disrupted. Just because the removed fat is mixed with PRP or something else doesn't make the blood and lymphatics magically re-appear. The fat at that point is not living tissue which means that it's prone to being dissolved by the body (most likely in an uneven and unpredictable manner). Injecting fat back into the face does not create the required elements to make the fat living tissue once again. So the argument that fat is alive and viable in the face once it's been removed and re-injected makes no sense to me as a physician and surgeon. The other issue that I have with fat transfer is the lack of precision. Fat is thick by nature which means it's not the same consistency as an off the shelf dermal filler. Fat injections use an increased volume injected in an attempt to compensate for the volume loss that "will" happen. This means a lack of specific shape and volume that simply can not begin to compare with the specificity of using a silastic facial implant of a "known" shape and volume. In that regard fat offers too much of an unknown to make it a reliable and predictable method for facial shaping. There's a significant difference between a 3mm and 5mm thick cheek implant. You can imagine the magnitude of difference there is between retaining 60% of 25cc's of fat versus 35%. In my humble opinion, I just don’t see how fat could possibly be used to precisely shape facial features? From the photos, even with the present swelling the cheeks are quite flat in the front and the chin is extremely weak. These combine to create an elongated, oval shaped face. Following my beauty principles, women look the most feminine, youthful and attractive with heart shaped faces. Heart shaped faces have cheeks that are full and round in the front. Cheek augmentation with a dermal filler or using silastic cheek implants for a permanent enhancement will create full, round cheeks that will feminize the entire face. I have performed many Chin Augmentations using chin implants for over 30 years. When the chin is weak, this creates an imbalance making the nose appear larger, the mid face top heavy and the lower face look short that de-emphasizes the lips and allows early formation of a double chin. Chin augmentation using a chin implant will add projection to the chin creating harmony and balance to the lower face. I have found that placement of a silastic chin implant, through a small curved incision under the chin (also allows excess skin removal) to be very safe, quick, highly effective and far less invasive than a sliding genioplasty. I perform chin implant surgery in 30 minutes or less, often using a local anesthetic alone. In my opinion, you are a good candidate for chin implant surgery. The back portion of your jaw line is also a bit weak and can be augmented, without making your face appear masculine, using precise placement of a dermal filler (I prefer using Restylane Lyft). Hope this helps.
