Ever woken up with a sleep crease? As skin ages, it loses elasticity and sleep creases - which are caused by friction and pressure on facial skin - can become more pronounced and longer-lasting. While the creases usually go away later that day, they can be gradually ‘ironed in’ over the years.

Sleeping on silk is a great expert beauty tip and a long-time beauty secret. Slipsilk™ has been shown to reduce friction by 43% on average*, allowing skin to glide along the pillow, which can reduce pressure on creased skin.

Technically, ‘satin’ isn’t a fabric; it’s a finish. The term ‘satin pillowcase’ is a misleading abbreviation that has occurred over the years, which generally means synthetic satin pillowcase. Synthetic satin (e.g. polyester) may feel nice and soft in your hand, but after an 8 hour sleep your hair and facial skin can really feel the difference.

Silk is a natural fibre, whereas ‘satin’ is petroleum based. It’s thinner, rougher and it ‘sweats’, essentially negating the benefits. Slipsilk™ pillowcases have a charmeuse finish, which is similar to a satin finish, but superior for the purposes of a silk pillowcase in that it’s a bit softer and breathes better.

You can tell if it’s a genuine slipsilk™ pillowcase because as well as the signature slip® embroidery, it doesn’t have that fake, super-shiny, reflective synthetic satin look.

All silk pillowcases are not created equal. Watch out for toxic dyes and false claims of momme (fabric weight/thickness).

The founders of slip® have personally travelled the world in search of the very best silk money can buy. We work closely with our suppliers to ensure that fair workplace practices are enforced and that only the highest quality materials are used. Made from pure mulberry silk with a thickness of 22 momme, slip® pure silk pillowcases are the very best available anywhere in the world.

Beware of imitations.

Slip® was founded in 2004. We are a family owned and operated business. Quality and customer service are our top priorities. After ten years of supplying hundreds of stockists across our home country of Australia, we are very excited to now be supplying the world.

Anyone with a head and a pillow!

Kids, mothers, fathers, grandmas, celebrities and everyone in between love sleeping on a slip® pillowcase.

We are very proud of our loyal slip® squad, some of whom have been sleeping on slip® pillowcases since 2004!

Absolutely. We work very closely with our suppliers to ensure that they meet the most stringent international standards.

Sadly the same can not be said for other silk suppliers. If you purchase a cheaper silk pillowcase online or in-store, you may not know what you’re really buying.

We work with one of the largest and longest running silk suppliers in the world. They take great pride in the quality of silk they produce.

It is with silk as it is with many things in life; you get what you pay for.

Momme is an old imperial measurement indicating the weight of the silk. The thicker or heavier the silk, the more it drapes, the softer it feels and the longer it lasts.

Unfortunately, less reputable suppliers measure the momme at different stages during the production process, rather than at the end. In other words, they claim a certain momme count but it’s false.

Slip® customers have remarked time and again how amazed they are by the difference. We guarantee our measurement of 22 momme.

Slip® pillowcases are available in two sizes. We have a standard international/queen size of 20” x 30” (51cm x 76cm) and a king size of 20" x 36" (51cm x 91cm). While we’d like to cater to everyone’s needs, these sizes are the most popular across all international markets.

If you would like to see us include a different size in our range, please feel free to contact us. Our company has grown over the years in direct response to customer feedback.

Traditionally, silk is hand wash and dry clean only. Ours are of the highest quality so they are machine washable, but they are still silk and need as much care as we can give them.

ALWAYS use a pH neutral liquid detergent and/or fabric softener. Silk is a natural fibre and washing in a solution that’s too acidic or alkaline can cause the silk to harden in a single wash. If you can't find a detergent that specifies pH level then just go for one that specifies silk. Do not use bleach products.

Another important factor is water temperature. Even just slightly above 30 degrees Centigrade or 85 degrees Fahrenheit can change silk dramatically. The safest method if your machine doesn't specify exact heat settings is either cold or just one level above cold.

A delicates bag is optional, depending on your washing machine and whether or not it tends to grab items and tear them.

If you wish to maximise the life of your pillowcase, hand washing is the ultimate method.

The gentler you wash your slip® pillowcase, the longer it will keep its sheen. The shinier it is, the better it will 'slip,' which is one of the benefits to its health and beauty qualities.

The same goes for drying your pillowcase, do not place in tumble dryer.

In other words, the better you care for your slip® pure silk pillowcase, the better it will care for you.
