Clinical and Demographic Characteristics of Acne in a Rural African Population: A Retrospective Study from Eastern Cape, South Africa

Background: Acne is a common inflammatory dermatosis with well-documented epidemiology in urban populations; however, data from rural sub-Saharan African settings remain limited. Objective: To characterize the demographic profile, clinical subtypes, severity spectrum, complications, and comorbidities of acne among patients attending a rural tertiary dermatology centre in the Eastern Cape, South Africa. Methods: A quantitative, retrospective cross-sectional study was conducted using census sampling of dermatologist-confirmed acne cases diagnosed between 2022 and 2025. Demographic and clinical variables were extracted from medical records and analysed using descriptive and inferential statistics (p < 0.05). Results: A total of 166 patients were included, all of African ethnicity. Females predominated (89.2%), yielding a female-to-male ratio of 8.2:1. Adult-onset acne was most common (85.5%), with a median onset age of 26 years. Acne vulgaris represented the predominant subtype (83.1%). Papules and comedones were the most frequent lesions, and facial involvement was nearly universal (94.8%). Moderate disease (Grade 2) was most prevalent. Post-acne complications were highly frequent (92.8%), with post-inflammatory hyperpigmentation being the most frequent of these (87.0%). Comorbidities were observed in 52.4% of patients, most commonly eczema and pigmentary disorders. Conclusions: Acne in this rural cohort demonstrated a predominance of adult-onset disease, marked female susceptibility, moderate severity, and a high burden of pigmentary sequelae. These findings highlight the need for context-specific diagnostic and management strategies in underserved rural populations.
