There are many different lip shapes. And, with that, there are some lip shapes that are more favored than others — especially by those who may not have that exact shape. For example, according to Byrdie, a cupid's bow is one of the most desired lip shapes because it resembles a heart, thus being a signal of romance. As for identifying whether or not you have a cupid's bow, simply look at your reflection and see if your upper lip looks like the letter "M."
When figuring out your lip shape, reference guides to common shapes, which can give you a good idea of what to look for. For instance, you may find you have bottom-heavy lips, round lips, or thin lips, per mindbodygreen. Identifying your lip shape can help in figuring out how to apply lip liner, lip gloss, or lipstick to either accentuate your natural pout or reshape your lips into another shape, such as full lips — which are typically symmetrical, with a top and bottom lip that are equally full.
As L'Oreal said, knowing your lip shape is the first step to unlocking your lip makeup look.
