Full Answer

One of the most common cause of chapped lips is dehydration due to excessive sweating or consumption of alcohol. The best remedy for dry lips caused by dehydration is to simply drink more fluids, including water and fruit juices. If the dry lips are caused by a toothpaste, the remedy may involve changing the toothpaste with one that does not contain sodium lauryl sulfate.

If the chapped lips are caused by an autoimmune condition, the best remedy involves the use of a lip balm to keep the area moist. Doctors may also have to treat an underlying cause before the condition is dealt with. Other remedies for chapped lips include avoiding lip-licking and breathing through the mouth.

While it is fairly common for people to experience chapped lips, a person should pay a visit to the doctor when sores that refuse to heal develop on the lips, according to the National Institutes of Health's MedlinePlus.
