I bought this pillowcase after attending an organic skincare products class. It was suggested, at the class, to purchase a 100%silk pillowcase for people who wanted to reduce wrinkles, acne, and allergies (from laundry detergents). I bought two so that I could have a clean one on hand at all times. I had searched around for a high quality silk at a decent price and this one was by far the most affordable and serves the purpose.
