While it might be tempting to lick your lips when they feel dry, it is necessary to resist the urge. When you lick, the saliva evaporates quickly, leaving the skin on your lips drier than before.
Keep your chapped lips nourished with the regular application of a healing lip balm like La Roche-Posay Cicaplast Levres Barrier Repairing Balm. It’s especially more important to keep a tube on hand for reapplication if you’re going to be spending time outdoors.
