September is Sexual Health Awareness Month, which means it’s a good time to make sure we know the difference between sexually transmitted infections (STI) and other conditions that could affect the sex organs. One common mix-up in that regard is a little-known issue called vaginal acne. Many women are unaware that pimples can arise in this region, and they sometimes mistake these small dots for an ingrown hair or an STI. Some simple insights could help to distinguish each—thereby avoiding unnecessary panic.
“Vaginal acne is actually more a form of folliculitis, or an infection of the follicle, rather than true acne,” Dr. Joshua Zeichner, the director of the Cosmetic and Clinical Research Department of Dermatology at Mount Sinai Hospital in New York, tells Newsweek. “Because of the high density of hair follicles, combined with hair removal, the hair follicles in that area of skin is at risk for bacterial infections.”
Vaginal acne commonly arises as individual pus pimples surrounding a hair. They can be caused by procedures like waxing or shaving, and tight clothing like workout gear. (Facial acne, by contrast, is not an infection. These pimples result when oil becomes trapped inside hair follicles due to bacteria living within them.)
Any woman could develop vaginal acne, but certain populations are more susceptible than others. Postmenopausal women, overweight women and smokers are more prone to vaginal acne, according to Margarita Lolis, a dermatologist based in New York and New Jersey. “Anytime there is hormonal fluctuations, excessive rubbing or perspiration in skin folds, plus circulatory issues, vaginal breakouts may occur,” Lolis tells Newsweek.
Knowing the Difference
Determining whether a red bump is a pimple, an ingrown hair or due to an STI can be tricky. To make matters more complicated, sometimes these spots may occur for no apparent reason and resolve on their own. A few considerations may help.
“Acne lesions tend to center on a hair follicle and are not painful,” Dr. Maral Skelsey, an associate professor of dermatology at Georgetown University, tells Newsweek. A virus called Molluscum contagiosum can mimic acne, says Skelsey, but the painless lesions usually have a central depression.
