There are millions of nerve endings around the lips. This is the reason they are so sensitive. There are is no protective tissue, which makes the lips extremely sensitive to external effects. Sweat glands are responsible for keeping the body moisturized. Since we don't have any sweat glands around our lips, they dry out fast. The tissue around the lips is actually opaque. Other areas of skin are composed of 16 different layers, however, the lips have only 3 to 6 layers. For this reason, the lips seem like they have a pinkish color.

As we age, lips begin to lose their plumpness.
