Exogenous inflammatory acne due to combined application of cosmetic and facial rubbing.

Background: Exogenous acne refers to acneiform lesions due to external factors such as cosmetic agents, exposure to various oils, skin rubbing or friction or chloracne, now better called metabolizing acquired dioxin-induced skin hamartoma (MADISH). Here we report a new form of severe inflammatory exogenous acne due to the association of two factors: facial friction with cosmetic agents.

Observations: A 15-, 17- and 19-year-old female presented at the department with severe inflammatory acne.
