Thanks for your question and notice the differing answers and opinions given so far by the board certified doctors that have penned to answer this question. Please have a consultation with a board certified dermatologist or plastic surgeon and learn what your treatment options are. Keep in mind, as well, that dermatologists are all about non-invasive procedures whereas some of the plastic surgeons see only the scalpel as the means to the end – which in this case is simply not needed if you choose a more non-invasive route.We have known for quite some time that the use of Botox, Dysport, or Xeomin in the masseter muscles can take a round face and when done correctly, make the face more oval. The Asian market has been doing these procedures for years and in fact, when you listen to toxin lectures in Asia, this is as important as the frown lines are to us here in the States. If you, in addition, need a little filler here or there for volume enhancement, we have Voluma, Perlane, Radiesse, and even Sculptra at our disposal to make the corrections that you are looking for.So find the right doctor, have a consultation, and take care of things as you feel best.
