Hi all,
I wonder if anyone can explain this: I have been using BareMinerals Matte foundation for a couple of years, and it's been great!
But now for the past few months all of a sudden my face gets warm, red and blotchy straight away when I apply it with the Kabuki brush, mostly around my lips and jaw line. I wash the brush regularly and thoroughly, and it even happens on the first use after washing it. I thought it was the heat, so I tried it in front of the open window, same result. Then I thought perhaps it's caused by my hair brushing against my jaw line and some sort of reaction with my hair product, so only did it with my hair up, same thing. 
I know that the bismuth can sometimes cause this, but I thought the matte version did not contain this. Also, and this is really strange, it can't be the foundation itself as my face is totally fine when I apply the foundation with the concealer brush.
Is it possible that the kabuki brush is making my face blotchy? Or something else? It all started right after I had an allergic reaction to antibiotics, could this have sensitised me to something?
