I think I have a small chin in comparison to the rest of my profile and whenever I close my mouth, it wrinkles. Probably due to sleeping with my mouth open growing up. What would be the best way to treat this? I'm open to both temporary and permanent solutions. Any other suggestions to improve my jaw area/side profile would be appreciated too. How would this treatment affect my face as it ages because I'm 18 and I have pretty chubby cheeks.
