If You Have The Cavity Between Your Nose And Upper Lip, Here’s What it Means
The vertical cavity between the nose and upper lip, also known as the philtrum, is where the face forms together in the womb. This happens while a fetus is 2-3 months old, and if it has not happened by that time, it most likely never will. Different races have deeper or more shallow cavities, which then determines the shape of the lips.
According to the FAS Diagnostic and Prevention Network, there is a guide used by medical professionals to measure the philtrum. Typically, the deeper the philtrum is, the larger the upper lip is as well.

If you have this cavity, it means you are simply human! The depth of it, however, can determine how other facial features appear.
