Sulfur
Sulfur is present in all living tissues. It is the third most abundant mineral in the human body. Sulfur seems to have antibacterial effects against the bacteria that cause acne. It also might help promote the loosening and shedding of skin.
Sulfur plays an important role in crucial functions in your body, such as making protein, regulating gene expression, building and repairing DNA, and helping your body metabolize food.
