In the U.S., by contrast, up to 95% of adolescents experience at least mild acne — a condition that often persists well into middle age. Rates of acne are similar in many other Western nations, and the rest of the world is catching up quickly. According to a 2021 study in the British Journal of Dermatology, the global incidence of acne has risen by more than 50% in the last three decades.
Lindeberg and his colleagues described his Kitava findings in a 2002 JAMA Dermatology paper. While the total absence of acne among the island’s inhabitants was striking, other remote…
