This article reviews the published literature about the efficacy of oral and topical zinc as treatments for acne vulgaris. The medical literature was systematically reviewed to identify relevant articles. Each published study was assessed for pathophysiologic results and the quality of the clinical evidence the study provided based on Strength of Recommendation Taxonomy (SORT) criteria. Finally, the body of evidence for using oral or topical zinc in the treatment of acne was assessed, again using SORT criteria. A SORT strength of recommendation of B (inconsistent or limited-quality patient-oriented evidence) appears to be appropriate for both oral and topical zinc. The preponderance of evidence suggests zinc has antibacterial and anti-inflammatory effects and that it may decrease sebum production.
