Victoria Beckham has revealed the overnight beauty secret she uses for great hair and skin

When Victoria Beckham shares a beauty secret, the world sits up and listens. From her favourite post-flight face mask to her go-to £8 moisturiser, she appears to have figured out the formula to flawless skin and hair – and her latest reveal is surely a contributing factor.

Posting in the stories section of her Instagram account, where she has more than 24 million followers, recently, VB revealed that she’s been sleeping on a Slip pure silk pillowcase – and she’s not the only one.

As lifestyle website My Domaine points out, silk pillowcases are a travel essential that supermodel Gisele Bündchen always carries too. The supermodel has been pictured at various airports carrying her $149 (approximately £111) SHH Silk Mixed Marble pillowcases, and judging from her appearance after landing, we’d say that the investment is paying off.

Another star that swears by the virtues of sleeping on silk is 90s icon Cindy Crawford, who told The Cut that she opts, like Victoria for a Slip case for her pillow, saying: ‘I’ve noticed that I’ve not only gotten fewer pillow lines, but it’s better for my hair.’

The equally gorgeous Rosie Huntington-Whitely agrees – when quizzed by Vogue for their 73 questions series, and asked for the supermodel beauty secret she’d be willing share, she said – you guessed it – ‘sleep with a silk pillowcase’. Ditto Jourdan Dunn (‘I’ll travel with a silk pillowcase, cashmere socks, loose sweatpants and a T-shirt’) and Chrissy Teigen (who shared a snap of her favourite case, also by Slip, on social media).

By now, we imagine you’ve noticed a pattern emerging – some of the world’s most beautiful women all use the same trick to protect their hair and skin from damage. So what are the benefits of sleeping with a silk pillowcase, and what should you be looking for when you invest in your own?

The benefits of using a silk pillowcase

‘Anyone spending money on face creams, serums and blow outs should be sleeping on a silk pillowcase. It is the perfect addition to your beauty routine and it is a well known beauty secret of dermatologists, hairstylists and beauty experts,’ says Fiona Stewart, Co-Founder of Slip.

‘As skin ages, it loses elasticity and sleep creases – which are caused by friction and pressure on facial skin – can become more pronounced and long lasting. While the creases usually go away later that day, they can be gradually ‘ironed in’ over the years. Sleeping on a silk pillowcase allows your skin to glide along the pillow while reducing extra pressure on creased skin.’

‘Sleeping on silk is also beneficial for your hair. Ordinary pillowcases can cause hair to pull and tangle throughout the night, leading to bed head in the morning and potentially damaging hair, whereas silk can help to reduce friction. The world’s most renowned stylists and beauty experts have long recommended sleeping on gentle, hair-friendly silk to help preserve your blowdry.’

However, not all silk pillowcases are created equal.’The quality of silk is vital – the better the silk, the more effective it will be,’ Fiona explains. ‘Slip silk™ is specially commissioned and made to our exacting standards, developed and refined over ten years to provide the ultimate combination of shine, thickness, softness and durability. We use the highest grade (6A) long fibre mulberry silk, with a thickness of 22 momme and enforce the strictest quality guidelines, including non-toxic dyes.’
