Bacterial and follicular cellular macromolecules

Bacterial and follicular cellular macromolecules represent the collective biological components, including proteins, lipids, and nucleic acids, within Cutibacterium acnes and the human pilosebaceous unit that serve as the site of action for certain topical dermatological agents. This target is most notably associated with benzoyl peroxide, which acts by releasing free radical oxygen species that non-specifically oxidize these macromolecules (StatPearls, 2023). This oxidative stress disrupts bacterial membrane integrity and metabolic pathways, providing a potent bactericidal effect against C. acnes without the risk of antibiotic resistance (PubChem, CID 2334). Within the skin's follicular cells, the interaction with these macromolecules can also influence the process of keratinization, helping to prevent the obstruction of pores and the formation of comedones (Journal of Clinical and Aesthetic Dermatology, 2017). Because the mechanism is non-selective, it affects both bacterial and host cellular structures, which often results in localized side effects such as dryness and irritation. This broad-spectrum approach is a fundamental strategy in managing acne vulgaris and other inflammatory skin conditions.
