The Epidemiology of Acne in the Current Era: Trends and Clinical Implications

Acne is an inflammatory dermatosis of the pilosebaceous unit that remains highly prevalent worldwide. In recent decades, the epidemiological profile of acne has evolved, with a rising incidence observed not only among adolescents but also in adult populations, particularly adult women. The current global prevalence is approximately 9.4%, reflecting its continued relevance as a public health concern. While early epidemiological studies were predominantly conducted in the United States and United Kingdom, recent data from diverse geographic regions highlight the need for updated, globally representative research. The Global Burden of Disease (GBD) initiative has recognized acne as a condition with a substantial impact on disability-adjusted life years (DALYs), underscoring its contribution to both physical and psychological morbidity. This review aims to synthesize current epidemiological findings, identify high-risk populations, and explore intrinsic and extrinsic factors influencing disease distribution and progression. A deeper understanding of acne’s epidemiology is essential to inform prevention strategies and improve outcomes in dermatological care.
