You’ve heard that silk pillowcases are the secret to a good hair day. And that the slippery fabric prevents you from waking up with pillowcase creases on your face. And that, because they’re lightweight and breathable, many dermatologists say they’re ideal for people with sensitive skin. It’s like they’re…“the greatest invention of all time,” to quote devotee Sophie Turner. But could they really live up to all that hype, especially when you consider that many cost $50 or more…for a single pillowcase? And if so, what’s the best one for your needs?
We put the top brands to the test, soon uncovering that the top brands tend to have a couple things in common. First, they’re made of 100 percent silk—often Mulberry silk, which tends to be softer. Second, they’re at least a 19 on the momme scale, which measures the weight and density of the silk (basically, it’s the silk equivalent of thread count). The higher the number, the denser and more luxurious the silk felt. These eight silk pillowcases exceeded our expectations, making converts out of all of our testers.
