How can I cure an irritation on my face due to a facial mask?

This happened to me a while ago. I used a mask on my face.A representative from the cosmetic company applied it. She put some on my eyelids. The next day, my lids were inflamed. She told me that a lot of people are sensitive to masks with clay base. I still don't know if that's true. I avoid masks now. I took a benedryl for the itching. It went away quickly.
