What treatment would be best for my deep labiomental fold? (Photos)

I would look into having a genioplasty! This is a permanent procedure that would add length to the bottom of your face, creating more facial balance. It would create a stronger jawline and softer chin. A genioplasty would improve the labiomental fold, decreasing the shadowing you have under your lips. They also have specific implants that can be placed to decrease the fold as well.

A deep mentolabial fold usually indicates that the chin is short in the vertical dimension. Treatment for this is a vertically lengthening genioplasty. You would likely benefit from submental and jawline liposuction as well to improve the contours of the mandible.

your lower jaw is underdeveloped and ideally a combination of orthodontics and jaw surgery will naturally balance the area. However, a simpler approach is a vertical lengthening genioplasty with any adjustment of the profile view/projection is the answer. Quite common. Ask a Maxillofacial Surgeon
