How Sulfacetamide / sulfur works
Sulfacetamide / sulfur is a combination of two medications that work in different ways to treat skin conditions.
- Sulfacetamide is a sulfa antibiotic that blocks bacteria from making a substance they need to grow.
- Sulfur is a keratolytic agent which means it helps loosen and remove dead skin cells. It's also thought to slow the growth of bacteria that can cause acne.
