There are a few things that are contributing to your individual facial contour. Each individual person‘s facial contour or individual “look” it’s primarily determined by skeletal structure. Soft tissues tend to be very consistent and it is bone structure that makes each person unique and recognizable. On the lower 1/3 of the face the maxilla is the dominant bone that has the greatest impact. When the Mandible is undersized compared to the Maxilla the platysma muscle tends to drape the neck in a more oblique fashion causing the following characteristics to happen prematurely. Premature jowls, a less defined jawline, formation of a double chin, and dental overbite occlusion, profile pictures that show the upper lip having more forward projection than the lower lip. 25 pounds is the substantial weight loss and well most people look better being at a lean healthy weight and some people can have facial implications. A jaw advancement(different than a chin augmentation) is beyond what most people are willing to undergo but your problem if you wanna call it a problem stems from the relationship between your mandible and your maxilla. In regards to my reasonable approaches fillers around the chin (especially pre-Jowell sulcus) can be helpful as can liposuction of the chin and neck. We need standard pictures to make a good assessment but it’s in augmentation may or may not be appropriate as well. It’s possible to have a Mandible that is small and lacks size and projection and still have a pointed chin. this facial skeletal combination is difficult to work with and often leaves providers perplexed of what the problem is or what to do. It is the underlying fundamental reason for you posting your question on real self. Expect to get different opinions from different providers for this. Most people will look at soft tissues and not skeletal structures as the problem and solution. Consider consulting with some oral surgeons or plastic surgeons for the cranial facial surgery backgrounds. They tend to see things more from a bone first perspective. I understand clearly that most people are apprehensive of having craniofacial surgery. it is however important to understand what the primary problem is because it helps people except the limitations of treatments that don’t address the primary problem. To get at least different opinions consult with local board-certified plastic surgeons, facial plastic surgeons and I would suggest maybe a couple of oral surgeons in your community and see what each has to say. Like I said, expect different opinions and a bit of diversity in explaining why certain treatments may be better. Best, Mats Hagstrom MD
