Is There a Way I Can Fix the Strange Shadow/Bulges Under my Lips?

For as long as I can remember I have had these bulges/saggy areas underneath my lower lip on each side like a bulldog's jaws. My cheek fat isn't sagging, it's by the 5'th from center teeth, which aren't bulging out or anything. I used to think It was because of my over-bite, but they don't go away unless I fake an under-bite to the point of it hurting. you can see in the picture how it looks, and that it bulges a lot on the side. What can I do about it?
