Background:

Acne is usually considered a disorder of adolescence, and a number of studies have examined the prevalence of this condition in the adolescent population. There are, however, relatively few data on the prevalence of acne in the adult population.

Objective:

A community-based study was carried out to investigate the current prevalence of facial acne in adults.

Methods:

Seven hundred forty-nine persons older than 25 years were examined for facial acne by means of the Leeds acne-grading technique.

Results:

A degree of facial acne was recorded in 231 women and 130 men, giving an overall prevalence of 54% (95% confidence interval [CI], 49-58) in women and 40% (95% CI, 35–45) in men (P<.001). The acne observed in volunteers consisted principally of physiological acne, but clinical facial acne (grade >0.75) was recorded in 3% (95% CI, 1.2–4.8) of men and in 12% (95% CI, 9-15) of women (P<.001). The prevalence of acne did not substantially decrease until after the age of 44 years (P<.001).

Conclusion:

This study shows a prevalence of clinical facial acne in women of 12%, which is likely to persist into middle age.
