The lower face is a critical area of the face to work on with fat grafting. If most of the questions have centered around the upper and midface with fat grafting, I think that is because it is the area that in most surgeons hands can be the most difficult area to achieve consistent results. Further, it is an area that tends to be the most important area to fix in most cases. In any case, I am glad you brought this point up if it is a point of confusion for the consumer out there.
Nevertheless, I am very focused on the lower face. In fact, I rarely perform partial face fat grafting unless, of course, it is a touch up procedure. I believe the entire face ages, including the area around the mouth, which must be addressed to achieve a balanced and global rejuvenation.
Now, let's explore where fat around the mouth and chin area works consistently well and where it consistently fails. Let's first discuss where it works very poorly. I don't believe that fat grafting is a good option to treat facial lines and for lip augmentation. The very highly mobile region of the mouth and the softer nature of fat make it a very poor choice to fill lines around the mouth. Interestingly, I do put fat in the lines around the mouth almost in every case since fat is free and I can usually at least get a little benefit from it, especially when you consider that when I augment the cheek area the line can actually look deeper from the shadow effect so I put fat in the smile lines just to offset that effect and not to entirely get rid of the lines. I also do not like fat in the lips because there is tremendously long distortion on the order of a several weeks to even over a month or two where the lips look absolutely frightening for a result that in many cases does not last owing to the nature of the highly mobile lip area. To augment the fat loss immediately around the lips will also not work well. Also, you have to be very careful since filling the white lip, i.e., the area just above and below the red lips can make the lips look like a duck if in fact the fat survives. I do put fat in this area in small amounts to help hopefully the stem cell changes that can occur after about a year that can possibly (and I emphasize possibly) help soften the lines over time.
Okay, where does fat work then around the mouth? Just like for the upper and central faces, it is critical to pad the chin and the prejowl area (in front of the jowl) to make the area appear more youthful. If you look at younger chins, there is considerable fat in the chin area that makes it look youthful. Fat in this area really works. I also use it to balance a lower face. If you have a person with very heavy jowls, neck and outer portion of the face, I can strategically put fat into the anterior chin to balance the heaviness of the outer face. It can also thereby soften the presence of the jowl. If it is a very early jowl, the jowl will be almost entirely gone or at least significantly improved. However, if you have a decent jowl, then a combination of microliposuction of the jowl itself and a face lift/neck lift is critical to get an optimal result.
I hope this answer is helpful.
best,
