Acne vulgaris (acne) is a chronic inflammatory skin disease that presents as open or closed comedones and inflammatory lesions. Comedones include blackheads and whiteheads, while inflammatory lesions include papules, pustules, or cysts. Acne is a common skin disease that predominantly affects adolescents and young adults, but can also persist into adulthood. Mortality is not associated with acne, although major physical and psychological characteristics may develop, such as acne scarring, poor self-esteem, depression, and anxiety. The distribution of acne in the population is influenced by genetic background and dietary habits.
For age- and sex-specific total prevalent cases, GlobalData epidemiologists utilized country-specific data from peer-reviewed journal articles, and for age-and sex-specific diagnosed prevalent cases and diagnosed prevalent cases by severity, GlobalData epidemiologists utilized a combination of primary research and data obtained from peer-reviewed journal articles. GlobalData epidemiologists forecast that the total prevalent cases of acne vulgaris in the 7MM will decrease by an Annual Growth Rate (AGR) of negative 0.13% per year over the next 10 years, from 157,919,985 cases in 2016 to 155,935,706 cases in 2026. GlobalData epidemiologists forecast that the diagnosed prevalent cases of acne vulgaris in the 7MM will decrease by an AGR of negative 0.13% per year over the next 10 years, from 78,960,002 cases in 2016 to 77,967,862 cases in 2026. In the 7MM, the US had the highest number of diagnosed prevalent cases with 32,308,734 in 2016, while Spain had the lowest number of diagnosed prevalent cases with 5,766,457 in 2016.
