Hi Robin. The Cupid's Bow is on the upper lip. The bow itself is the two uppermost points of the upper lip that reach up toward the nose.
The cupid's bow is the shape of the upper lip where the sides of the upper lip meet the central part called the central tubercle and philtrall collums. These anatomic finds lead to a well shaped and attractive lip. There are natural variations in definition, e.g. Angelina Jolie vs Michelle Pfieffer, but aging causes you to lose this definition. Restoration can be achieved with different procedures depending on your speciific findings. Good luck!
