Hi, I am in my mid twenties and one side of my jaw is less defined than the other. I seem to have more fat at the side of the mouth running downwards making it look like the side of my face is sagging. I feel it is the very early signs of jowls to come. I would ideally like my jawline tighter and as contoured as possible with the fat gone from the jowl area and more volume in my cheeks so that I have more of a V shape to my face. What would be the best course of action to achieve this?
