If your skin troubles persist even after changing expensive cosmetics, suspect the pillow.

I was worried about persistent, unexplained chin and cheek acne, so I started washing my pillowcase every other day. It's said that the sweat, saliva, and oil from our hair that we shed while we sleep can cling to our pillowcases, creating a breeding ground for bacteria. If you find daily laundry too much of a hassle, simply sleeping with a clean towel on your pillow is enough. Even just changing this one habit will make your skin feel much more soothed.
