I highly recommend you do not put fat into your chin. Chin implants have limits to size/shape and are semi-unpredictable. You are a good candidate for a genioplasty. This would bring your chin forward and slightly down, creating more facial balance and the projection you are looking for. It will also add length and definition to your jawline. The benefit of a genioplasty is that it lasts forever, and the whole procedure is done through the mouth, which means no external scarring. I would say a genioplasty would be the best option for you to achieve your aesthetic goal. Our office provides morph photo simulations of your expected outcome, so you have a better idea of what the result would look like. We would be happy to schedule a consultation to discuss your options further!
