We all wish we could wake up glowing with flawless skin and freshly blown-out hair. In reality, mornings can be a little rough. Sometimes “beauty sleep” doesn’t seem to do its job. You wake up to hair that’s dry and tangled. And somehow, those fine lines seem to be showing more than they were yesterday. The problem could be with your pillow.

Cotton pillowcases are a breeding ground for bacteria. They collect the oil and dirt that’s on your skin then transfer it back to you. That’s why if you go a couple weeks without washing your pillowcase, you may notice you have more blackheads or blemishes than usual. In addition to exacerbating acne-prone skin, cotton pillowcases soak up moisture as you sleep, leaving you with dryer, potentially irritated skin and hair. Your nighttime moisturizer is also less effective if it’s getting absorbed more into your pillow than your skin.

The solution? Opt for a silk or satin pillowcase. Because they’re less absorbent than cotton, the result is better hydrated skin and hair. Furthermore, a silk or satin surface reduces friction to minimize hair breakage, and the smoother texture creates less frizz for more great hair days. They’re also hypoallergenic and draw in less pore-clogging bacteria. For side sleepers, silk or satin pillowcases reduce skin creases and can even help prevent wrinkles.

From a purely aesthetic standpoint, making the switch also makes sense. Silk and satin pillowcases look more luxurious than their cotton counterparts — and they are! From dreamy purple to satin pink options, these pillowcases immediately elevate your decor.

How do you decide between a satin versus silk pillowcase? Most options are either charmeuse silk or polyester satin. Silk is a fiber formed by silkworms, while satin is a fabric weave (and therefore blended with other materials). As you can probably guess, polyester satin is a blend of both polyester and satin. Charmeuse silk is made purely from silk, and it’s known for its lustrous look and soft feel.

Because silk is harder to produce, it’s considered a luxury product and comes with a heftier price tag. Compared to satin, silk is more lightweight and breathable. Silk is also smoother and more delicate, typically requiring a careful handwashing. Both silk and satin pillowcases boast many beauty benefits, so you really can’t go wrong. Silk is slightly more absorbent than satin, though, so for moisturizing benefits satin pillowcases are your best friend.
