What procedure(s) would you recommend for a square face with a weak chin? (photo)

A chin implant combined with liposuction of the chin/neck area yields a great result that patients are generally very happy with. I would recommend a consult with a board certified facial plastic surgeon. He/she will evaluate you in person and provide you with the best advice. I hope this helps, and I wish you the best of luck.

Good question.  I think that you have nice cheeks that have adequate volume, and are nicely shaped.  You would have a nice change by augmenting your chin in both the amount of projection and the height.  Although every face is individual, in general, an aesthetic lower face has somewhat defined proportions.  When you look at the distance from the bottom of the nostrils to the point of the chin, 1/3 of that distance should be between the bottom of the nostril and the small opening between your upper and lower lip when your face is at rest.  The other 2/3 should be between this point between the lips, and the point of the chin.  As you can see in your face, the vertical height in each of these sections is almost equal, so we would want to vertically lengthen your chin from the front view.  From the profile view, we would want to increase the projection of your chin so it is more in line with the front leading edge of your lips.  This would give a nice natural and balance result.  There are a huge variety of chin implants and we would be able to find one to fit your needs.
