Had braces, but my teeth relapsed. 7 years later and starting Invisalign treatment - will my facial structure go back?

I had braces for 6 years (I know) and stopped wearing my retainer. So, my teeth relapsed... and badly. 7 years later, I noticed my jawline and lower face shape has changed dramatically, even from 2-4 years ago. I am beginning Invisalign treatment soon, and am wondering whether realigning my teeth and fixing my bite will help my face shape go back to the way it was. (Reference: I used to have a pretty defined jawline, but now it seems like my lower jaw is slightly swollen.)
