I'm in my early 20's, light smoker of 4 years(recently trying to quit) years ago I noticed an asymmetry in my jaw, the right muscle is more developed, jowls run in my family but my left jowl has always been larger and over time has become distinctly larger than the right. I have to different profiles, the left in most light has a pronounced slit from the corner of my mouth to my jaw. I know everyone has asymmetry but I'd like to know if there is any way to tighten the skin on the left side
