Question by Princess Leia: How does the sulfur in some acne products actually help clear acne?
I have 2 acne treatments (Proactiv Refining Mask & another drying gel) that have sulfur as the main ingredient. They smell horrible, but they really work well! I was wondering what it actually does? Does it clear the pores or does it kill the acne bacteria? No big emergency, just wondering! Thanks!
