Many people complain about chapped lips both in the summer and winter times. Many times chapped lips are not due to any extreme weather but instead due to a lack of humidity. For example, if you breathe through your mouth while you are sleeping, your lips will lose most of their moisture. The easiest fix for this situation is to keep a humidifier going wherever you sleep. Using coconut oil on your lips will also keep them soft and moisturized. Other over the counter products also work, but most dermatologists recommend that you wet your lips with warm waters before applying products with paraffin wax to get the best effect.
