Totally dopey question about facial musculature!

amyloooo

I'm almost 58. I'm getting pretty satisfied with the improved looks of my body, but have been despairing that the parentheses beside my nose/jowls and mouth/chin have not shallowed out as much as I might have hoped. Just recently as I near my goal this has been improving, but I'm not sure it if has been of my doing or it would be happening anyway. In recent weeks I have been straining my face muscles as I do other strength training exercises -- but I don't know if that's contributing to the improvement or I'm wasting my time? Experts on this out there? Would love to hear opinions. Thx. Amy
