The Best Silk Pillowcases to Help You Get Your Beauty Sleep

Overnight face masks and hair masks aren't the only eight-hour beauty treatments. Silk pillowcases are another nighttime product that can help both your skin and your tresses. After all, we spend a third of our lives in bed. So what we sleep on is important.

Not only do they feel divine, silk pillowcases are less abrasive and less absorbent compared to cotton, polyester or even satin. (FYI: Satin is not the same as silk.)

"Silk pillowcases do provide a smoother surface than cotton which has the potential to reduce friction against skin," says board certified dermatologist Dr. Dennis Gross. "By bunching up less, it's possible silk pillowcases can help to prevent the formation of wrinkles from mechanical collagen breakdown." Gross reports that there's not enough scientific evidence to support silk pillowcases being better for skin and hair health. But some brands offer some interesting stats on their silk pillowcases.

Co-Founder and CEO of Slip Fiona Stewart reports that the brand's specially commissioned Slipsilk absorbs significantly less face cream and creates 43 percent less friction on average versus cotton pillowcases with 220 to 360 thread counts. Similarly, many brands tout the benefits of anti-tangling, anti-creasing and the all-around addictive experience of sleeping on silk. But it's essential to care for your silk pillowcase properly because a dirty one can still lead to breakouts.
