Causes of Lip Dryness

Dry lips are a common complaint during the winter months. The condition can be embarrassing and distressing when it is prolonged. The skin on the lips is very thin and does not contain many glands which secrete lubrication. Thus the skin is easily dehydrated and prone to dryness. In most cases the cause of dry lips is obvious but in some cases, the cause is never found.

The common features of dry lips are:

Cracked lips. Lines and fissures along the lips indicate that the lips are dry. Many times the lines are only present in the corner of the mouth but in severe cases, the lines may be visible along the entire lip.

Lip licking. Frequently licking the outer lips with your tongue is a sign of drying (unless you are trying to covey a sexy message). Most individuals with dry lips will continuously lick the lips to prevent them from drying up.

Peeling: When drying is moderate to severe, the skin on the lips will start to peel; this usually starts off in the center of lips where the skin is the most fragile

Cracking: Cracking of the skin along the corners is a common feature of lip dryness

Bleeding: Frequently, the lips will tend to bleed during the drying; the lips also become tender at this point

Open ulcers or sores are also common feature of prolonged skin dryness.

Causes of lip dryness
