In technical terms, the lips are the transition state between facial skin that can be considered dry and wet skin that resides inside the mouth. Because of this, the lips have certain properties that differ from the skin on the rest of the body. It is important to note these differences in order to pursue effective lip treatments.
Properties of Lips
• lips contain no sebaceous (oil) glands
• lips contain no sweat glands
• the skin on the lips does not contain hair
• lips are composed of very thin skin layers (3 to 5)
• lips contain no skin pigment and therefore blood vessels are able to show through the thin skin and the lips appear red
• people with darker skin have some pigment and therefore the red lip colour is less prominent
• lips have many nerve endings making them sensitive to touch, warmth, and cold
• lips are very elastic and pliable because they do not have any direct bony attachments
• lips aid in the eating function by holding food and drink in the mouth
• lips help keep unwanted objects out of the mouth
• lips visibly express an individuals emotions and play a key role in facial expressions
