Collapsing, sunken cheek when I smile. What can be done? (Photo)

I’m 36 yo and my right cheek wrinkles horribly when I smile, making my face look old and sunken. I even try to avoid smiling because of this.. When not smiling my face look pretty normal, no dents on my cheeks. What’s the best solution to give my cheek some volume and make it look rounder and more compact? I don’t know if I should try the new generation poly-d-l-lactic acid, a simple lipo-filling, a soft hyaluronic acid injection, or even Morpheus.
