Acne in Skin of Color: Unique Considerations

Overview / Definition Acne vulgaris is a chronic inflammatory skin condition characterized by the presence of comedones, papules, pustules, and, in more severe cases, nodules and cysts. While acne affects individuals of all skin types, those with skin of color (SOC) often experience distinct manifestations and complications, particularly concerning hyperpigmentation and scarring. Epidemiology Acne prevalence is significant across diverse ethnicities, but data indicate that individuals with skin of color may experience: Higher incidence of post-inflammatory hyperpigmentation (PIH) compared to those with lighter skin. Differences in the severity of acne lesions. Variation in treatment response and complications. Pathophysiology / Mechanism The pathogenesis of acne involves several factors: Increased sebum production due to androgen stimulation. Follicular hyperkeratinization leading to comedone formation. Colonization of Propionibacterium acnes, eliciting an inflammatory response. In skin of color, there may be variations in the inflammatory response and healing processes, which can lead to more pronounced PIH and scarring. Clinical Presentation Clinically, acne may present differently in skin of color: Lesions may be deeper and more inflamed, often leading to higher rates of scarring. Post-inflammatory hyperpigmentation is more pronounced and can last for months to years. Acne may also occur in atypical locations, including the back, shoulders, and chest. Diagnosis / Workup Diagnosis of acne in skin of color is primarily clinical but may require consideration of: Assessment of lesion type and distribution. Evaluation for potential secondary causes, such as hormonal disorders. Consideration of the patient's skin type and history of hyperpigmentation. Treatment / Management Management of acne in skin of color should be tailored to minimize complications: Topical treatments: Include benzoyl peroxide, retinoids, and salicylic acid, with caution to avoid irritation.
