Did the hollowing of your cheeks go well after the Shurink treatment?

I want to try Shurink, but since I don't naturally have much fat on my face, I'm most worried about my cheeks sinking in.
I just want to refine the area under my jaw and my facial contours a little, but I'm worried that losing weight in my cheeks might make me look older.

Has anyone else with little facial fat like me tried Shurink?
I'm also wondering if it's okay to get the treatment done by adjusting the area.
