What is the Best Solution for Marionette Lines Caused by Too Heavy Cheeks and Weak Chin?

I am 24 year old actress and I have beginning marionette lines caused by chubby lower cheeks. I think my "cheekbone" area is projecting less because the fat is moving downwards (so my contours are gone now). I also have a weak chin and notice my face aging in an asymmetrical way. I'm very fit and use good skincare (retinoids and good suncreen everyday since my mid-late teens). Could fillers be a good solution to these problems? I don't want to take drastic measures with surgery just yet.
