Smile as you wish :
Most people get chapped lips from time to time. Dry, cracked or sore lips can interfere with many daily activities, such as smiling, kissing, eating and talking.
Chapped lips are the result of very dry skin. Dry skin occurs when the moisture content of the skin is decreased for any reason. Dry winter air chaps lips.
When the lips do become chapped it is very common for people lick their lips in an attempt to moisten them. Unfortunately, even though saliva soothes momentarily, it digests the lips rather than moistening them. This makes the lips and surrounding skin even more dry and irritated. The people lick their lips again, providing brief relief, but afterwards leaving the lips in even worse shape. This vicious cycle leads to painful, cracked, bleeding, lips.
