Hi, I have performed many facial shaping procedures including chin augmentations, using a chin implant, over the past 30 years. From the photos, your chin is still a bit weak creating an imbalance that makes the nose appear larger, the lower face short and the mid face appear top heavy. A larger size chin implant will add projection to the chin creating harmony and balance to the lower face. I have found placing a silastic chin implant through a small, curved, incisions under the chin to be very safe, quick, highly effective and far less invasive than a sliding genioplasty that requires bone cuts with placement of screws and metal plates. Following the beauty principles outlined in my book on face and body beauty, male faces look ruggedly handsome when there is angularity in the cheeks, chin and mandibular angles. In addition to chin augmentation, cheek augmentation with either a dermal filler or cheek implants (for a permanent enhancement) will add angularity to the cheeks. Mandibular angle augmentation with a dermal filler (jaw implants IMHO have too many unwanted side effects) will add volume, angularity and flare to the jaw line. Hope this helps.
