Lip anatomy matters more than you may think!
The lips are made up of key structures, including the vermilion border (your lip line), the orbicularis oris muscle (controls movement), and important vessels like the superior and inferior labial arteries (providing blood and oxygen to the lips).
In medical aesthetics, understanding these layers is essential for safety, informed practice and facial assessment.
Lip anatomy matters more than you think ✨
The lips are made up of key structures — the vermilion border (your natural outline), the orbicularis oris muscle (controls movement), and important vessels like the inferior labial artery.
Did you know, some people’s orbicularis oris muscle can be stronger or more active, causing the lips to “tuck” inward or “disappear” when smiling and laughing.
If you’re curious about your own anatomy and what influences your lip shape, we can explore this together during a personalised consultation.
