How often should I apply lip balm or ointment to my chapped lips?

Lip balm seals cracks in your lips and ointment keeps your lips hydrated for a longer duration based on the ingredients and thickness of the ointment. Lip balms and lip ointments can be applied as needed throughout the day when you notice your lips are dry. Using lip ointment at night will keep your lips hydrated throughout the night. Always reapply lip balm or ointment after eating and drinking. While outdoors, apply lip balm or ointment with SPF 30 or higher about every two hours.
