Vermilion Border
The Vermilion Border (pronounced: ver-mil-yuhn bor-der) is the slightly raised edge that demarcates the lips from the surrounding skin.
Etymology
The term "Vermilion Border" is derived from the Latin word 'vermilion', meaning 'red', and 'border', referring to the boundary. The term is used due to the reddish color of this area.
Description
The Vermilion Border is a crucial anatomical structure that forms the boundary between the facial skin and the redder, more sensitive skin of the lips. It is more prominent in humans than in most other animals, contributing to the facial expressions that are part of human communication.
The Vermilion Border is also the area where cold sores and actinic cheilitis often occur. It is also the area that is highlighted when applying lipstick or other lip cosmetics.
