My smile is very small, small mouth, and flat face (Photo)

I really do not like my facial features. I am currently using Invisalign and am 1/2 way through those treatments. My profile is really flat and my mouth turns down. I would like to know what further could be done to enhance my facial structure. Without surgery if possible. I am also taking 50mgs of Adalactone for the hormonal acne. Thank you!
