Anyone who has enjoyed a luxurious night of sleeping on silk probably doesn’t need any more convincing about the benefits of a silk pillowcase because the pure luxury of feeling its slinky fabric against your skin is all the reason you need. But for those of you who are yet to give silk ‘slips a go, this list of impressive benefits for your skin and hair is just what you need to finally add to cart and treat yourself.
Silk pillowcases won’t absorb your skincare
We hate to break it to you, but a lot of that good work you’re doing treating your skin to potent formulas during your nighttime routine is all going to waste because cotton pillowcases soak up what’s sitting on your skin. Silk, on the other hand, is less absorbent than most fibres, so it helps keep your skincare on your face and it is less likely to zap your skin of moisture while you sleep, too.
They help prevent lines and wrinkles
Another problem with pillowcases made with fabrics like cotton? Their rough textures cause friction between your skin and the pillowcase’s surface as you toss from side to side throughout the night. So what? Well, this motion causes tugging on your skin - and your hair, too, by the way - which can encourage lines and wrinkles to form. Silk’s smooth surface is gentle on your skin and hair, helping them to stay crease-free.
Silk is considered a more sustainable fibre than cotton as it’s a natural, renewable and biodegradable fabric that uses less water, chemicals, and energy to produce than many other fibres.
Silk won’t cause frizz and hair breakage
In the same way that normal pillowcases create friction between your skin that can lead to wrinkles, the friction between your hair and pillowcase can create frizz and cause breakage. Cotton is also more porous, which means it absorbs moisture from your hair - silk will help ensure your strands stay hydrated while you snooze. If you’ve splurged on a blow-dry you’ll also want to make sure you sleep on silk afterwards because it helps preserve your style’s sleek finish.
They’re good for all skin types
Silk takes good care of all skin types, especially acne-prone skin and extra dry complexions. Because it is gentle and doesn’t cause as much friction, it won’t cause inflammation which can make acne and sensitive skin worse. It also doesn’t absorb natural oils and bacteria from skin like cotton does, which means you’re not going to transfer all those nasties and grime back onto your skin each night. For dry skin types, silk is a great option because it doesn’t zap vital moisture from your skin while you sleep. Additionally, sensitive skin will love its naturally hypoallergenic properties (i.e.no build-up of dust mites, fungus, mould, and other allergens).
In laboratory testing, Slip's exclusive slipsilk™ was shown to absorb significantly less face cream and create 43% less friction on average compared to widely available cotton pillowcases with a 220-360 thread count.

Tips for choosing the best silk pillowcase
Ok, so you’re well and truly convinced to sleep on silk. But how do you pick between all the options that are so readily available these days as everyone from Kmart to Country Road and Sheridan are selling them? These are our top tips for choosing a silk pillowcase:
1 / Make it mulberry. Think of mulberry as the silk version of Egyptian cotton. Opt for the highest grade (6A) mulberry silk - its fibres are long and more uniform, which equals a smoother and more durable fabric.
2 / Momme matters. Momme refers to the density of the silk and indicates the quality of the fabric. We recommend a 22 momme or higher.
3 / Consider a non-toxic option. When it comes to Australian silk pillowcases (or any worldwide for that matter), we can’t go past Slip. We love that they tick all the above boxes and only use non-toxic dyes.
