Suggestions for a more defined jawline, surgical or nonsurgical? (photo)

Since you've already undergone chin liposuction and a sliding genioplasty, and you're now aiming for further jawline definition, particularly without increasing frontal width - a silicone jaw implant will be a suitable next step. Silicone mandibular angle implants can enhance the lower jaw by adding definition and vertical length at the back (posterior jawline), improving contour and projection from the side view without broadening the face from the front.
Silicone is biocompatible, durable, and permanent, making it a safe option.
Implants can be tailored to blend smoothly with your existing bone structure and the results of your previous genioplasty, ensuring a more balanced and harmonious lower face.
