Input (grade 12): Lip balm or lip salve is a waxy substance applied topically to the lips of the mouth to relieve chapped or dry lips, angular cheilitis, stomatitis, or cold sores.
Output (grade 12): Lip balm is often used during the winter, because the cold winter winds can dry out a person's lips so that they are cracked and hurting (this is called having "chapped" lips).
