Chap Stick acne.
Abstract
We describe two patients with an unusual, limited form of acne manifest as a single row of large, open comedones along the entire cutaneous margin of the upper lip. The acne began after repetitive application to the lips of Chap Stick in one patient and petroleum jelly (Vaseline) in the other. It was treated successfully by eliminating the Chap Stick and petroleum jelly, respectively, as well as by microincision and expression of the comedones. Petrolatum, the major ingredient of Chap Stick, appears to be responsible for this type of acne.
