10 bottles of this cult overnight anti-ageing serum are sold every minute

Popular beauty products may pop up frequently, but those that reach cult status are much rarer.

But the Advanced Night Repair serum by Estée Lauder that has managed to climb the ranks, becoming a 'holy grail' product for huge numbers of beauty fans.

And it seems that the numbers agree, as Estée Lauder told W&H that 10 bottles of the magic serum are sold every minute around the world. That's 600 bottles an hour!

In just one year, Estée Lauder sold 5.7 million bottles of the stuff globally, so it's clear that many shoppers wouldn't be without the product. And today, on World Sleep Day, it's easy to see why the product that claims to renew and hydrate your skin overnight, while you snooze, is so popular.

The anti-ageing beauty staple claims to leave you with more youthful-looking, radiant skin, working its hardest between 11pm and 2am, when your natural skin recovery is at its peak.

The oil-free forumla is designed to target fine lines and wrinkles, leaving you with a fresher, more toned looking face.

It's not cheap, with prices set at £55 for 30ml, and up to £93 for 75ml. But it seems many customers agree that it's totally worth it.

On the Estée Lauder website, plenty of fans have praised the Advanced Night Repair serum, where it's won almost a thousand 5* reviews.

One wrote, 'Omg where have u been my whole life, absolutely amazing stuff for my face I notice the difference the next day.', while another agreed saying, 'This is an amazing product. I wear it in the morning and night and can see a huge difference in my complexion. I recommend it to everyone.'

Other shoppers also mentioned that although the product is expensive, a little of it goes a long way, so you won't get through it too quickly.

But if that weren't enough, Estée Lauder have also announced a brand new initiative to help customers find the perfect products for their exact skin requirements - if the Advanced Night Repair serum isn't for you.

The beauty brand have partnered with Google to launch the first ever virtual beauty advisor, Liv. Powered by the Google Assistant (so you'll need to have one, or a Google Home device, if you want to try it), the service wants to allow shoppers to personally experience and discover Estée Lauder products that suit them, in the comfort of their own home.

They said that the service aims to 'connect with consumers, deliver a quality and informative experience and enable consumers to test, learn and engage with the products with the option to purchase.'
