Frequently Asked Questions
What causes bacne—and how can you prevent it?
“Bacne develops for many of the same reasons facial acne does,” Dr. Shah says, pointing to excess oil production, clogged hair follicles, bacterial overgrowth, and inflammation as common culprits. “When dead skin cells and oil build up inside the pore, they create an environment where Cutibacterium acnes bacteria can thrive, leading to breakouts,” she explains.
But unlike the skin on the face, “the back naturally contains larger and more active oil glands than many other areas of the body, which can make acne there appear deeper and more persistent,” says Dr. Shah. Once you factor in excessive sweat, tight clothes, oily hair products, and hormonal fluctuations, bacne can be hard to avoid—but not impossible. That’s why Dr. Camp recommends showering as soon as you can after workouts, wearing breathable clothes, and using noncomedogenic skin and hair-care products in order to reduce your likelihood of developing bacne.
What active ingredients should you look for when shopping for a bacne spray?
The tried-and-true actives found in facial acne treatments will help with bacne too. Dr. Shivakumar points to salicylic acid, which exfoliates and unclogs pores, and benzoyl peroxide, which reduces acne-causing bacteria and inflammation, as excellent options. (Heads up: If you apply a product with benzoyl peroxide to your back, wear an old or white top, because the ingredient can bleach your clothes.) Don’t stress if you notice that they come in higher concentrations than you’re used to seeing in facial products. The thicker skin on your back tends to be more tolerant of stronger products, Dr. Shivakumar explains.
You can also look for products containing alpha hydroxy acids like glycolic acid, Dr. Camp says: “[They] may help improve skin texture and post-inflammatory discoloration left behind by breakouts.” And folks with sensitive skin may prefer the gentler effects of antimicrobial hypochlorous acid, which targets acne-causing bacteria with less risk of irritation and dryness.

How we test and review products
When Allure tests a product, our editors look at it from every angle in an effort to best serve you. We review ingredients, scrutinize brand claims, and, when necessary, examine peer-reviewed scientific and medical studies. In addition to testing each and every product that’s included in each and every review, we rely on experts who shape their fields, including dermatology, cosmetic chemistry, and medicine, to help us vet the ingredients and formulas.
For our list of the best bacne sprays, we considered each product’s performance across five primary categories: product ingredients and efficacy, packaging, fragrance, texture, and product wear. Every product was determined to have excelled in each category by our editorial team, which is composed of in-house writers and editors as well as contributors—along with special consideration from board-certified dermatologists. To learn more information on our reporting and testing processes, read our complete reviews process and methodology page.
Our staff and testers
A beauty product is a personal purchase. You might be searching for a face cream to address persistent dryness or a new nail product to add to your Sunday self-care routine; you may simply be browsing around for the latest launches to hit the hair market. No matter what you seek or your individual needs and concerns, Allure wants to ensure that you love anything we recommend in our stories. We believe that having a diverse team of writers and editors—in addition to the wide range of outside testers and industry experts we regularly call upon—is essential to reaching that goal.
After all, can we really say a skin-care product is the “best” for people over 50 if the only testers we’ve solicited opinions from folks who have yet to hit 30? Can we honestly deem a high-end diffuser worthy of your hard-earned cash if it’s never been tested on curls? We’re proud that our staff spans a wide range of ages, skin tones, hair textures, genders, and backgrounds, which means that we are able to fairly assess any beauty product that comes into the beauty closet.
