“…Comedones can be evoked in acne subjects by excessive washing with some soaps-acne detergicans (Mills & Kligman, 1975a)-However, our subjects washed with water only and had no evidence of healed acne. Acne mechanica or the exacerbation of acne due to friction is a well recognized entity (Mills & Kligman, 1975b) but there is no evidence that new cysts or comedor^es are produced; the lesions are caused by rupture of incipient comedones at the site of the pressure.…”

Truncal Acne: Pathophysiology, Clinical Features, and Management Strategies

“…Some studies suggest that the association between sebum production and truncal acne is less pronounced than that observed for facial acne, and that its pathogenesis may be more strongly influenced by mechanical factors [23]. The term "acne mechanica," first proposed by Mills and Kligman in 1975, describes inflammatory acne induced by mechanical stimuli such as friction, pressure, traction, tight clothing, or occupationrelated rubbing [29]. Prolonged occlusion by clothing, creating a warm and humid microenvironment, may further exacerbate local inflammation [30].…”
