Sulfur is keratolytic (unclog skin pores), antifungal, and antibacterial activity. Accumulation of dry keratin of the skin surface and in the openings of the skin pores is the primary cause for blackheads whiteheads and future acne breakouts. When applied to the skin, sulfur interacts with cysteine to form hydrogen sulfide that can dissolve excessive keratin that accumulates in skin oil glands and on the skin's surface. Sulfur was also found to inhibit the overgrowth of P. acnes as well as some Streptococci, and Staphylococcus aureus.
How does sulfur work in Rosacea?
Sulfur has an inhibitory effect on Demodex mites, which explains its effect on rosacea. One study compared a 10% sulfur cream to taking oral antibiotics (tetracycline). This study showed that sulfur cream induced a more significant reduction in the inflammatory components of rosacea than oral antibiotic treatment. The relapse rate within six months was similar for both treatments.
