In comedonal acne, patients develop open and closed comedones, but may not develop inflammatory papules or nodules. Mild acne is characterized by comedones and a few papulopustules. Moderate acne has comedones, inflammatory papules, and pustules. Greater numbers of lesions are present than in milder inflammatory acne. Nodulocystic acne is characterized by comedones, inflammatory lesions, and nodules greater than 5 mm in diameter. Scarring is often evident.
