Lip-licking dermatitis (lip licker's dermatitis) is a chronic irritant contact dermatitis caused by repeated exposure of the upper and lower cutaneous lips to salivary contents. This condition is common among young children, but it can present in adolescents and adults.

Characteristically, it presents as erythematous, scaly papules coalescing into circumoral plaques, with secondary crusting and fissures. In darker skin phototypes, hyperpigmentation may be more apparent than erythema. Patients often complain of dryness and burning.
