I used to use facial clay masks, the ones you get at Walmart. They always worked well on my skin. I hadn't used one in about a month, so today I decided to use it right after my shower. I left it on until it dried, like usual, and used warm water to wash it off. When I took it off, my skin was red and blotchy in the spots of the mask. I'm putting a cold rag on it to try and get rid of the redness, but it's not helping all that well. What do I do?
