Procedures to Improve Bottom Heavy Face?

While you are not fond of the idea of the chin implant, that may still be the best choice.  A chin implant would be placed against the bone of your jaw so that it feels like an extension of your natural jawline.  Not only would this improve your jawline and front profile, but it would also improve your side profile and the contours of your neck.  I believe that a facelift or neck lift are more aggressive approaches than you need at this point.

Liposuction alone will probably not do the trick. It maytake a tightening of the deep layer, the platysma. We prefer a wide interlacing verison of the platysmaplasty.

I know you are set against the chin, but it can have some beneficial effects on the profile, the span of the neck, and the appearance from the front (even during periods of "play") if subtly done.

A minilift can also provide an extra measure of sculpting of the jawline if appropriate.
