Acne Vulgaris
Key Points
If noninflammatory, acne is characterized by comedones and, if inflammatory, by papules, pustules, nodules, and cysts. Mild and moderate acne usually heals without scarring by the mid 20s. Recommend that patients avoid triggers (eg, occlusive cosmetics and clothing, cleansers, lotions, high humidity, some drugs and chemicals, possibly a high intake of milk products or a high-glycemic diet). Consider the psychologic as well as the physical effects of acne. Prescribe a topical comedolytic (eg,tretinoin) plus, for inflammatory acne,benzoyl peroxide, a topical antibiotic, or both. Prescribe an oral antibiotic for moderate acne and oralisotretinoinfor severe acne. Treat cystic acne with intralesionaltriamcinoloneas needed for acute lesions.
