I've been having a problem for months with itchy raw eyelids. It's taken me a while to figure out what it was. I suspected my Chocolate Bar palette but sometimes I had no reaction at all. Turns out half the shades in the palette include this potentially irritating ingredient and so does my Shadow Insurance Primer I have loved for a while. Right along my lash line and outer corners were bothered the worst. That is where I line my eyes with the shadow since I don't usually use eyeliner. I checked other TF palettes and see they used this ingredient in all the palettes I checked. Looks like no more Too Faced for me. I was such a huge fan too. Oh well, at least half my palette will still work for me. I just thought I would bring this up in case anyone has been having any issues. I guess you can just become allergic to bismuth at any time!
