I have a very long gap between my nose and mouth. I thought I was being neurotic as it’s been a concern for years. Then I stupidly measured and it’s about double the length it should be. I have also started developing lip lines when I smile or talk. I can’t stand this area of my face. What can I do? I am in my late 40s. I am worried the mouthguard I have to use for my tmj is making it worse. Otherwise I am fine with how I look.
