The photos provided suggest central and mid-facial deflation and lack of definition of the posterior angle of the mandible. These problems can be quite readily addressed with the proper injection of volumizing fillers, which are intended for precisely for these types of volumizing, shaping, and contouring issues. Treatment should take about 20-30 minutes to perform and typically engenders an immediate "Wow!" response. My choices for volumizers in my Upper East Side Manhattan office would be Voluma XC and Radiesse Plus. (In my Israel satellite facility, where a far greater number of regulatory agency volumizing fillers are available, I would opt for Stylage XXL, Emervel Volume and Teosyal Ultra Deep for these purposes). I suggest you consult with a board certified aesthetic physician with experience and expertise in nonsurgical facial contouring in men (There are significant differences between treating men and women). Be sure to ask to see his/her before and after pictures.
