Acne
Acne vulgaris is a distressing condition related to the pilo sebaceous follicle and which is considered as an ‘adolescent’ disorder. It is characterized by spontaneous resolution in the late teens or early twenties in the majority of cases. The first publication about the epidemiology of acne was in 1931 by Bloch [1]. Already at this time, the onset of acne was noted slightly earlier in girls (12.1 B 1.5) compared to boys (12.8 B 1.7 years), retentional lesions being the earliest lesions (13% at 6 years and 32% at 7 years of age). Since this publication, no significant evolution has been noted concerning the age of onset of acne. According to different studies of the literature performed in different countries in the world, the mean onset of acne is 11 years in girls and 12 years in boys, remaining earlier in girls (1 or 2 years) with mainly retentional lesions (open and closed comedones). However, adult acne has also been described recently.
