Faint drooping on one side of my face. Options to fix asymmetrical cheeks?

On one side of my face, I have a defined "cheekbone" (soft tissue over my cheekbone) that casts a shadow. On the other side of my face, I do not. I think that this is because of the soft tissue under my skin on that side of my face has drooped somewhat for whatever reason. There is faint drooping along my jawline on that side, even though I am in my early 20s. I'm interested in having the less defined side of my face look more like the more defined side of my face. Is there a good way to do this?
