Which procedure will fix my puffy cheeks/fat face?

I have a fat face, but I am not overweight. I do not like how there is that shadow under my chin. I would like to hear your advice on how to fix my face. (Chin implant/augmentation? Buccal fat removal? Liposuction?) I am not interested in losing weight. Even when I was a few pounds less in the past, my face was still a bit puffy. Also, my natural resting face looks like a bit like I am frowning. If there is any way to fix that too, please let me know. I appreciate any comments.
