Have You Ever Wondered Why Your Lips Are Pink?

Spoiler: blood.

A lot of people are sort of, kind of, totally obsessed with lips.

Maybe it's because your lips are really unique. For one, you probably noticed that the skin on your lips is pink.

That's because there's more blood flowing near the surface of your lips.

There's more blood vessels in your, uh, genitals too.

Why are there so many blood vessels in our lips?
