Many people are troubled by dry scaling and formation of fissures in the lips and corners of the mouth. This maybe due to lack of some of the vitamins, particularly riboflavin and pyroxidine. Some people have the habit of constantly licking and moistening their lips, and this may also contribute to the trouble. Hydrocorstisone cream applied once or twice daily will usually clear this up. High does of vitamins B complex and well-balanced diet will also help to heal cracked lips.
