The overlip, also known as the upper lip, is the top lip above your mouth. It frames the upper teeth and plays a crucial role in facial expressions. Think of it as the curtain of your mouth. 👄 Unlike the lower lip, it's usually less mobile. It works with the lower lip to form various sounds during speech. It's also a key area for applying lipstick or lip balm. The philtrum, the vertical groove above the overlip, is a unique feature.
