The skin on the lips is then and has no sebaceous glands, which makes it particularly sensitive in winter. Cold, heated air and constant licking can lead to chapped and cracked lips. Dermatologist Dr. Ellen Meyer-Rogge recommends using products with panthenol and zinc for chapped corners of the mouth. Licking your lips should be avoided, as it removes protective lipids and dries them out further. She recommends the use of lip blams with wax and natural oils. You could also make your own lip balm with beeswax or shea butter and coconut oil. Exfoliating loose flakes of skin is not recommened; instead, use a gentle lip scrub made from honey, olive oil and sugar.
