Hi, based on the pictures it’s hard to determine. But you may benefit from a combo approach. Botox in the masseter muscles will reduce clenching and eventually atrophy the muscle. This may not sounds good, but if you chew a lot of gum or clench your teeth, then this muscle is thickened or hypertrophied. The botox, reduces the function of the muscle and therefore it will eventually thin out. That will help with one aspect of the face slimming. Next would be to evaluate adipose tissue. I cannot say for sure based on the pictures you posted, but if there is a little bit of fat near the “jowl”(which you don’t have!), then off label kybella may help reduce this adipose tissue as well. The combo treatment should give you a more slimmer look. The final treatment to consider would be ultherapy or Morpheus 8 treatment. These are skin tightening treatments, both can give a “shrink wrap” effect of the skin for someone as young as you and can be the finishing touch for a more contoured slimmer face.
