How to deal with chapped lips?

Lip chapping is another manifestation of dry skin. The skin in this area is a lot more thin than skin elsewhere on the body. So exposure to cold, wind, sun will have a bigger impact on the lips than other exposed parts of the body. People who have the habit of licking their lips are at a greater risk of this condition. Patients who have certain medical conditions or on certain medications can also develop chapped lips. Excessive sun exposure is another risk factor. Using a petrolatum based lip balm with a sunscreen 3-4 times a day will work well for this problem. Applying a lip balm before brushing your teeth is another good idea. Hydrating yourself well through the dry season is a must.
