title: Acne enigmas and some pure hypotheses about them.
abstract: The enigmas of why acne usually starts and stops at certain ages, why and how it so often cures itself, are recalled and some explanatory hypotheses are mentioned. Certain other enigmas are mentioned including why some patients have much oil and little acne, and some vice versa; why some blackheads and whiteheads initiate inflammation and suppuration and others not; why cysts and why scars form in some patients and not in others. Enigmas such as these show that acne is not only a common disease that supplies the practitioner's bread and butter, but one offering almost unequaled opportunities for research.
