The famous white line especially on the top lip yes its f***ed yes its emabarrasing in my opinion is just skin becoming soft and soggy in contact with salivia which causes a clear puss substance.. f***ing frustrating if you chew gum or eat then the lines dissapears for me the white line always forms the worse worse @ night... Try eat a early lunch and go for a walk in a little bit windy environment and leave your mouth open a bit and it will go for a little while.. it always appears when talking heaps it sucks.. its like the skin rolls especially on he top lip and also the bottom lip always in the inner centre you can see were the white sloath appears same place no matter way it almost is like a little triangle and e colour is frankly different if you look closer..
