The contour of the lower 1/3 of your face and neck is primarily determined by bone structure. That contributes to some degree, but nothing in comparison to bone structure, which is the primary determinant of what gives each person, their unique facial appearance. The single anatomic variant that determines if somebody is attractive, or a unattractiv, masculine or feminine is bone structure. Soft tissue coverage tends to be fairly consistent from person to person and wild obesity creates an obese appearance. It doesn’t fundamentally change who someone is or what your face looks like other than being overweight or thin. Individuals who have a double chin, universally have issues related to the mandible being small or lacking in forward projection. This in turn causes the platysma muscle to drape the neck in an oblique fashion, like you demonstrate in your picture. Liposuction can give subtle improvements, especially on individuals who have a substantial amount of fat to remove and especially if done by somebody who’s really talented a Chin neck Liposuction. Liposuction results vary substantially among different providers so finding someone who has mastered the procedure is paramount in maximizing the chance of getting a quality outcome. Augmenting the chin can be helpful in individuals who have a weak chin but there’s not extend the body of the Mandible, and will not impact how the platysma muscle drapes the neck. Jaw advancement surgery can be an option for some individuals, depending on their dental occlusion and overall mandibular size. I suggest having consultations with both plastic surgeons and oral surgeons in your community. Plastic surgeons tendency things more from the soft tissue perspective while oral surgeons tend to see things more from a facial, skeletal perspective. Both specialties contribute greatly to aesthetics in this part of the face. Neck lifts are appropriate for some individuals and there are a few other procedures that could be considered. I’ve seen a few providers do suture suspension of the neck in young men with the same type of neck characteristics that you have with good results. To make an assessment, we need to see the entire face because issues related to the mandible are always on a relative scale. In other words, it’s not the size of the mandible itself, but rather the size of the mandible, in comparison to the Maxilla. Best, Mats Hagstrom, MD
