Your Upper Lip Is What Joins Your Face Together

In the medical textbooks, the focus isn’t so much on the two bumps, but the groove or dip between them. This groove, which extends down from your nose to your lip, is called the philtrum.

The bumps serve no purpose themselves, but are in fact a remnant, a seam if you will, of the way your face developed when you were about 6 months away from being born. In that sense, it is not unlike the bumpiness of a scar where a deep cut has grown back together. Three parts of your face actually grew together, joined, and fused into one solid and lovely smooth upper lip.

Being that we develop no different than most other mammals, you’ll find other animals with prominent philtrums.

About 1 in 700 babies may be born with a cleft lip, or “hare lip”, where in the upper lip has not completely joined together, leaving a bit of a gap.
