I keep hearing about injections such as Sculptra or Radiesse to treat volume loss in the face. What I don't hear mentioned is the fact that a great deal of this volume loss is due to shrinking facial muscle and (to a lesser extent) facial bone.
Is there anything on the market in the U.S. or abroad that can add volume to the facial muscles? If there isn't, how can plastic surgeons justify using Radiesse to "add volume" to the face without restoring the muscle underneath first? Won't a face look unusually fleshy when you plump up just the skin to compensate for lost muscle volume?
