Sulfacetamide sodium / sulfur
"I used to pay $75 without insurance for this cream because it worked so well. I used it so sparingly like it was gold, but it could clear my face in just 1-3 days. Last time I tried to get it the price had gone up to $140 and the pharmacist said it had been discontinued. I moved to the UK and couldn't find anyone who had heard of it. Just by a fluke I was on Amazon recently (Oct 2015) and saw a 10% sulpher soap advertised on the side. When I searched for it, I found several types for under $7.50 for a BIG 200g bar. They also had a cream. My face was very swollen and red from being in the sun and lots of humidity I think. Within 3 days of using the soap twice a day followed by the cream my face was completely clear! Love it!"
