Bismuth is not good for my skin either. My first foundation was Isadora, which is really similar to BE. I loved the finish and I loved how it glides on the skin. However after few days, my skin started to itch. After the whole day the foundation was getting into my pores and made my skin so oily.
I still have one jar of this foundation, wanted to sell it, but never got time. I was ready to give up with MMU when I discovered that there is plenty of companies which are making foundation without bismuth.
I also found this forum while I was trying to figure out what on earth is irritating my skin in this wonderful and purely natural mineral foundation
