Extracellular vesicles (EVs) are small membranous vesicles secreted by bacteria that participate in bacteria‐host interactions.MethodsThis study first compared <jats:italic>C. acnes</jats:italic> EVs from AD lesions (AD‐EVs), acne lesions (Acne‐EVs), and healthy skin (NC‐EVs), using Label‐free quantitative LC‐MS/MS and validated differently expressed proteins by parallel reaction monitoring (PRM).
