Acne occurs when bacteria living on the skin, particularly Propionibacterium acnes, mix with sebum (oil) and dead skin cells, creating a plug in hair follicles. This plug can rupture, leading to inflammation and the release of bacterial secretions into internal tissues, causing further inflammation and the development of acne lesions.
