basically im still a teen and a few months ago i noticed that on the bottom part of my lower lip theres a white line. its basically on the border between normal skin, and lip skin. does anyone know what this is?
Samtarly....The first thing I thought of when I read your post is a scar??? I know several people who have a white line-scar in the same place from falling and biting through their bottom lip when they were toddlers...just a thought!
