Then don't use it!!
. First time I ever tried foundation was Bare Minerals. My face would itch when I wore it and I would try to soothe it by rubbing my face. That made it feel better, but essentially, what I was doing was removing the make up. I thought it was cause my face was a 'virgin' and I just wasn't used to wearing make up. I used the whole set (which lasted a year cause I'm not a frequent make up wearing) before noticing it was the makeup. After researching, I discovered that many people are allergic to mineral makeup (the bismuth oxychloride). This ingredient is in a lot of mineral makeup, but not all. Not sure if this is your issue, but try another brand of mineral makeup that doesn't contain the bismuth. Everyday Mineral was a decent alternative. But now a days, I just use the Clinique rosacea line. I have mild rosacea so it's ok for me. And if I start to flush, I just run to the bathroom and reapply (keep it on me at all times). I prefer liquid though. I think all that rubbing and swirling with the mineral makeup is harsh on my skin!!
