Comedonal acne
Open comedones (blackheads) and closed comedones are the first acne lesions to appear. Some become inflamed and become papules or pustules.
Closed comedones, or whiteheads, have a very small orifice. This impedes drainage. They respond slowly to treatment.
Open comedones remain for months. Stretch the skin for support, and remove them with a comedone extractor.
