Another simple and natural solution for chapped lips is cucumber. 1  Rub a small slice of cucumber across your dry lips gently so that the juice is applied well over them. 2  Leave it on for 15 to 20 minutes and then wash your lips with water. 3  Do this several times a day to help your lips heal faster.
It causes faster evaporation of moisture from your lips. 1  During summer heat, ensure that you drink enough water to hydrate your body. 2  Seal your lips to prevent excessive loss of water to the environment.  If your lips are already dry and chapped as caused by the summer effect, apply olive oil when going to bed.
