Comedonal Post-Adolescent Acne Most Common Form Of Adult Acne In Women, Mayo Clinic Study

Published: Jul 20, 2010

‘The study that was recently published in the Journal of the American Academy of Dermatology, shows that CPAA (Comedonal Post-Adolescent Acne) is the most common form of adult acne in women, a finding that dispels the previous widely held belief that papulopustularpost-adolescent acne (PPAA) predominates,’ explains Dr. Marcy Street, MD.

Additionally and of very high significance is that the study showed that CPAA was usually of late-onset and closely attributed to cigarette smoking.

Post-adolescent acne affects approximately 14% of women between the ages of 25 and 50 years, and its incidence is increasing. It is described as a predominantly inflammatory, mild-to-moderate form, characterized by papules and pustules, mainly located on the lower third of the face, jawline, and neck, with rare and not prominent comedonal lesions.

In the study, the researchers recruited 226 women aged between 25 and 50 years presenting with acne. In all, 192 (85.0%) patients were classified as having CPAA and 34 (15.0%) as having PPAA. Patients with CPAA were, on average, older than those with PPAA (39.1 versus 32.3 years). Late-onset acne accounted for 45.1% of all cases and was more common among patients with CPAA, at 48.9%, than among those with PPAA, at 23.5%. Smokers represented 66.3% of the whole cohort, but there were significantly more smokers among the CPAA than the PPAA group, at 72.9% and 29.4%, respectively. Furthermore, a positive correlation was found between number of daily cigarettes smoked and CPAA severity. (AAD)

Dr. Street says, “The findings will affect our treatments, and we will need more products with Vitamin A and alpha and beta hydroxyl-acids to clear the skin along with exfoliating products, as well as more education for the public at large about the damaging effects smoking can have on the body’s largest organ, the skin.”
