All characteristic lesions of acne vulgaris can occur in skin of colour, but it usually presents with less discernible redness and more postinflammatory hyperpigmentation (pigmented macules) which persists long after the acne lesion has gone. Post-inflammatory hyperpigmentation is often the major reason for seeking medical attention, causing significant psychological effects. Pomade acne occurs more commonly in people with skin of colour due to cultural practices with hair styling products in African American and Hispanic populations. The use of greasy hair products leads to follicular plugging and comedones along the hairline. Keloid scarring is more common in skin of colour following acne lesions, particularly along the jawline, chest, and upper back. Postinflammatory erythema Acne grading Acne may be classified as mild, moderate or severe. Comedones and inflammatory lesions are usually considered separately. Mild acne <20 comedones <15 inflammatory lesions Or, total lesion count <30 Moderate acne 20–100 comedones 15–50 inflammatory lesions Or, total lesion count 30–125 Severe acne >5 pseudocysts Total comedo count >100 Total inflammatory count >50 Or, total lesion count >125 Mild acne Moderate acne Severe acne Some dermatologists assess the severity of a patient's acne more precisely by using a grading scale. The inflammatory lesions are compared with a set of standard photographs to determine the grade, which may be 1 (very mild) to 12 (exceptionally severe) for example. In clinical trials evaluating acne treatment, the numbers of non-inflamed and inflamed lesions are carefully counted at regular intervals. It is remarkably difficult to count consistently. What are the complications of acne vulgaris? Postinflammatory hyperpigmentation Scarring, including keloid scars Psychological effects of acne What is the treatment for acne vulgaris? Treatment for acne depends on the patient's age and sex, the extent and the severity of the acne, how long it has been present, and response to previous treatments. Treatment for mild acne includes topical anti-acne preparations, lasers and lights Treatment for moderate acne includes antibiotics such as tetracyclines and/or antiandrogens such as birth control pill Treatment for severe acne may require a course of oral isotretinoin.
