Acne pathophysiology is complex, involving altered sebum production and composition, abnormal keratinization, microbiome dysbiosis, and skin inflammation. Conventional therapies, such as topical retinoids, antibiotics and benzoyl peroxide, are the first-line treatments for mild-to-moderate acne, but antibiotic resistance and local adverse effects can have a negative impact on therapeutic outcomes, leading to a growing interest in alternative strategies for disease management. The use of dermocosmetics is increasingly being recognized as a useful strategy to improve treatment outcomes and patient adherence.
