The dip below the nose, known as the philtrum, is the vertical groove that runs from the bottom of the nose to the upper lip. It plays a role in facial aesthetics and expression, contributing to the overall shape of the face. Additionally, it is thought to have functional significance in the development of the face and may assist in the perception of pheromones. In various cultures, the philtrum is also associated with beauty and can be accentuated in cosmetic procedures.
