I noticed that when I smile, the right side of my mouth turns up and there is a distinct "corner" to my lip if that makes sense. The left side however is softer and isn't as sharp. Is there a way I can fix that? I feel like my muscles are stronger on the right side of my face because it's very easy for me to move it in certain ways but I can't for the left side. Also, how can I get a bigger, wider smile?
