A mild incidence of acne vulgaris is usually addressed with topical over-the-counter acne medications and a rigorous skin cleaning routine that removes excess oil and dirt. More serious acne may develop in sensitive individuals, including acne conglobata (severe acne with connected nodules under the skin) or acne fulminans (highly destructive inflammatory acne). Such incidences may require medical intervention, which usually involves treatment with isotretinoin. Topical anti-androgen drugs are also under investigation for the treatment of severe acne, and have shown a great deal of promise in early trials. Acne is typically resolved with the cessation of steroid use, although the overproduction of sebum may persist until the sebaceous glands have had time to atrophy back to original size. Serious forms of acne may produce lasting scars.
