Hexachlorophene
"I used hexachlorophene before it was taken off the market.  I used it once and it burned my face so badly I had to see a dermatologist for months and repeatedly have my face scraped   and wrapped like a mummy. I wasn't the only one in my family to use it. Three of us used it at the same time. We all had a chemical burn but mine was worse because  my skin was much  lighter. The company then came out with Phiso-Hex. I  never used it, but I would suggest to use extreme caution or better yet find something without hexachlorophene in it."
