Sulphur has natural anti-inflammatory and antibacterial properties, meaning it can clear bacteria from the pores that would otherwise lead to acne and also help to prevent new bacteria from manifesting on the skin's surface. It also reduces the production of sebum in the skin, which leads to oiliness. As a topical acne treatment, sulfur works similarly to benzoyl peroxide and salicylic acid. ... Sulfur helps dry out the surface of your skin to help absorb excess oil (sebum) that may contribute to acne breakouts. It also dries out dead skin cells to help unclog your pores.
