Dry lips are caused by dehydration and by weather (the cold, wind) so drink water and cover your mouth with a big cowl or scarf during the winter. There are two types of chapsticks or lip balms: those that protect, like ones with vaseline and bees wax, and those that heal and soften, like ones with oils in them. If your lips need to heal from being dry, cracked, or chapped, give your lips a scrub with a bit of olive oil and sugar, and cover them with a healing balm overnight. Then everyday use a protectant!
