Ah... I used a pillowcase I haven't used before, so it all flipped inside out on the cheek side.

A few days ago, I was too lazy to wash it, so I just slept with a spare pillowcase I hadn't bothered to use. But like magic, starting the day before yesterday, tiny bumps started appearing all over the cheek and along the side of my cheekbone where they touched. I can't believe my skin is this sensitive; it's just ridiculous. I'm really painfully realizing now that the saying "cleanliness of bedding starts with cosmetics" applies to skincare. I'm going to run the washing machine over my duvet and pillowcases as soon as I get off work today. Do you all use cotton covers, or do you use something like silk?
