The Skin of the Lip
Skin of our lips is structured differently than the skin of our face.
The part of the lips that we’re discussing here is called the “vermillion,” which can be identified as the “red part” of the lips. In contrast to the other skin on our face, the vermillion has no hair follicles and no salivary, sweat, or sebaceous glands.The margin of the lips shows a transition between the thicker and thinner skin, represented by the Vermillion Border. It accentuates the appearance of a sharp line between the colored edge of the lip and the adjoining skin. This red border/zone is the demarcation between the lip and the adjacent normal skin.
