Hi, I have performed many facial shaping procedures using dermal fillers, facial implants (cheek, chin), liposuction and/or facelifts for over 30 years. From the photos, your cheeks are flat anteriorly (in the front), there is excess fat in front of and below the cheeks and the chin is weak. These combine to create an oval shaped face. Following the beauty principles outlined in my book on face and body beauty, 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 cheek implants for a permanent enhancement will create full, round cheeks that will feminize the entire face. I would combine this with liposuction to reduce the excess fat for further shaping of the cheeks.
Think of facial beauty as something that "must" address all layers of the face including the skeletal structure of the cheeks and chin, the overlying SMAS muscle, amount and position of subcutaneous fat and finally the degree of skin laxity. It's an "urban myth" that pulling tissues over flat cheeks and a weak chin can create a beautiful or handsome face. Similarly, dermal fillers or facial implants alone can't lift and remove excess skin from the face and neck. Natural looking beauty is created by the aesthetic vision of what tissues layers need to be adjusted by what technique and amount. I have performed many Chin Augmentations using chin implants for over 30 years. From the photos, your chin is weak. A weak chin 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.
Hope this helps.
The cheeks can be contoured and treated with implants, liposuction, fillers. I suggest you see an expert for treatment options. Best, Dr. Emer.
