Propionibacterium acnes

Propionibacterium acnes is a type of bacteria commonly found on the skin. While usually harmless and part of the natural skin flora, it can sometimes contribute to acne by infecting hair follicles and causing inflammation. This bacteria thrives in oily environments, especially during puberty when oil production increases. It plays a role in the development of pimples and skin redness, but it is just one factor in acne, which also involves hormonal and immune responses. Understanding its role helps in managing and treating skin conditions related to acne.
