Topical application of phenolic compounds suppresses Propionibacterium acnes-induced inflammatory responses in mice with ear edema.

Acne vulgaris (AV), a severe chronic inflammatory dermatosis, commonly treated with systemic or topical antibiotics that exacerbate bacterial resistance and pose adverse side effects, new approaches for suppressing or reducing Propionibacterium acnes-induced inflammatory responses and thereby treating AV remain necessary. In response, the goal of our study was to investigate the therapeutic potential of phenolic compounds in the in vivo inflammatory process induced by P. acnes.
