title: Biological purpose of acne.
abstract: It is argued that the close endocrine control of human sebaceous glands and the likely effects of acne on selection indicate that both gland and disease have persisted because they are biologically useful. Two possibilities are proposed: sebum may provide precursor substrates for metabolism and synthesis by the epidermis of compounds of both local and systemic importance; and the adjuvent properties of corynebacteria which colonise the active sebaceous glands of acne may facilitate certain general immunological membrane.
