Chapped lips can result from several things including sun or wind exposure. Licking the lips frequently can also cause them to become dry.

Chapped lips can also be a result of certain medical conditions, including allergic reactions, skin conditions and dehydration, according to the New Health Guide website. To help prevent dry or chapped lips, people should drink plenty of water daily, avoid licking their lips and keep their lips moisturized. Exfoliating the lips and applying sunscreen when heading outdoors can also prevent them from becoming dry. Avoiding acidic foods or other products that irritate the lips is also important.
