A kiss is the touching of one person's lips to another place, which is used as an expression of affection, respect, greeting, farewell, good luck, romantic affection or sexual desire. The word comes from Old English cyssan "to kiss", in turn from coss "a kiss". Kissing is a complex behavior that requires significant muscular coordination; a total of thirty-four facial muscles and 112 postural muscles are used during a kiss. The most important muscle involved is the orbicularis oris muscle, which is used to pucker the lips and informally known as the kissing muscle. In the case of the French kiss, the tongue is also an important part. Lips have many nerve endings so they are sensitive to touch and bite.
Lips are a visible lip part at of humans and many animals. Lips are soft, movable, and serve as the opening for , as an erogenous organ used in kissing and other acts of intimacy, as a tactile sensory organ, and in the articulation of speech.

Anatomical basics of the human lip
One differentiates between the Upper (Labia superfluos entafada) and lower lip (Labium inferius). The lower lip is usually somewhat larger. The border between the lips and the surrounding skin is referred to as the vermillion border, or simply the vermilion. The vertical groove on the upper lip, is known as the philtrum.
The skin of the lip, with three to five cellular layers, is very thin compared to typical face skin, which has up to 16 layers. With light skin color, the lip skin contains fewer melanocytespigment, which give skin its color). Because of this, the blood vessels appear through the skin of the lips, which leads to their notable red coloring. With darker skin color this effect is less prominent, as in this case the skin of the lips contains more melanin and thus is visually thicker. The skin of the lip forms the border between the exterior skin of the face, and the interior mucous membrane of the inside of the mouth. (cells which produce melanin).
The lip skin is not hairy, and does not have sweat glands or sebaceous glands. Therefore it does not have the usual protection layer of sweat and body oils which keep the skin smooth, inhibit pathogens, and regulate warmth. For these reasons, the lips dry out faster and become chapped more easily.
In this case normally a beauty consultant will recommend to apply "lip gloss".
Anatomy in detail
The skin of the lips is stratified squamours epithelium. The mucous membrane is represented by a large area in the sensory cortex, and is therefore highly sensitive. The Frenulum Labii Inferioris is the frenulum of the lower lip. The Frenulum Labii Superioris is the frenulum of the upper lip.
