We just learned about the bumpy spot on the upper lip called the Philtrum.
Another part of the mouth is the White Roll.
Right above where the lip changes from pink to normal skin color, there is a line where it is lighter than the rest of the skin on the face.
For a light skinned person this is almost white, so it is called the white roll.
For a dark skinned person it won't be white, but it will be lighter than the rest of the skin on the face.
The white roll shows up more for young people, and as people get older it gets less white and sticks out less.
Sometimes people will go get plastic surgery to make it stick out more to make themselves look young again.
