What Causes Bacne
Breakouts on the back, often called “bacne,” can be a source of distress. Dealing with acne on the face is challenging enough, but when it shows up on the back, too, it hardly seems fair. But what causes bacne has nothing to do with fairness, and—this might surprise you— everything to do with the same factors that trigger facial acne.
What is Bacne?
Whether you’re dealing with mild bacne, severe bacne, or both, the underlying causes are the same:
- Propionibacterium acnes bacteria within the pores cause aggravation.
- The aggravation leads to visible redness.
- Excess oil (sebum), tiny hairs, and debris get backed up in the pore lining.
- The oil serves as a food source for P. acnes, allowing it to flourish.
- You see various sizes of red, often uncomfortable, pimples dotting skin’s surface.
Along with a couple of other factors, including family tendency toward acne, the series of events above is what causes acne on the back. Bacne is not caused by dirty skin, eating chocolate or fried foods, or just being a teenager; indeed, adult acne can show up on the back, too.
The problem is that bacne tends to be more stubborn than acne on the face. For some reason, it’s simply more difficult to treat. But if you stay on top of it with a consistent routine, you can banish back acne (and make sure it doesn't come back).
