Detailed answer

Sulfur cleansers are effective in reducing blackheads because sulfur has antimicrobial properties, which can help kill bacteria that contribute to blackhead formation. Sulfur also has mild exfoliating properties, which can help to remove dead skin cells and unclog pores, reducing the occurrence of blackheads. However, it's important to note that individual results may vary and it's recommended to use sulfur cleansers as part of a complete skincare routine that includes cleansing, exfoliating, and moisturizing.
