It's not a commonly discussed topic, but what you sleep on can affect your health, hair and skin.
It might feel good to lay your head on a cotton pillow – but you'd be far better off with silk. Here's why...
"Silk has serious beauty benefits," says Sarah Chapman, London's most sought-after facialist. "Naturally hypoallergenic, silk helps to regulate body temperature, keeping skin calm, cosseted and comfortable.
"And because silk is less absorbent than cotton, sleeping on it means your skin retains its natural moisture to stay hydrated and healthy."
Sarah recommends Gingerlily's silk pillowcases, which consist of 'the finest 'A' Grade long-fibre mulberry silk'.
Silk contains the same proteins and amino acids which are naturally found in skin, meaning that after sleeping on silk, your skin will feel plumped and revitalised.
But silk's benefits don't just lie with your skin. It is anti-static, meaning it will significantly reduce bedhead hair.
"The hair doesn't stick to silk in the same way that it does to cotton; the hair shafts remain smoother and glossier," says Michael Cimino, previous Artistic Director at Michaeljohn and Umberto Giannini.
You can even go one step further and make sure your whole bedding is silk – this will help to control temperature and beat dust mites!
