ABSTRACT
Acne vulgaris is one of the most common disorders encountered in dermatology
practice accounting for approximately 8.8% of total visits to office-based der-
matologists in the United States in 2006 (1). Treatment of acne in teenage
patients accounts for greater than 2 million visits annually (2). Although peri-
pubertal onset is most common, prepubertal onset is not uncommon, and several
acne patients present after the teenage years, with approximately 10% of visits
noted in patients 35 to 44 years of age (2,3). The negative psychosocial impact of
acne in many affected patients is well documented (4,5).
