What can be done about sagging cheeks after jaw surgery? (Photos)

I understand your concern. I would recommend volume to the face to get a better contour. If too much is required, consider fat grafting over fillers. Facelift at your age is not usually indicated. Of course in person assessment is helpful. Best wishes

Thank you for your question and photos. You are definitely not a candidate for a facelift at your age and lack of true laxity.  I would recommend Ultherapy procedure if you are not interested in fillers. Ultherapy is a non surgical approach to improve tissue laxity (to give you a lift to the lower jawline and neck) plus it helps build collagen.  Make an appointment for a free consultation to discuss more details.  Best of luck to you
