Keira Knightley's MZ Skin face tool cools, tones and lifts tired-looking skin - and it's so affordable

For mornings when your face feels all puffy or just whenever you think it could do with some sculpting, this is the toning tool Keira Knightley says is 'magic.'

While the best facial moisturisers can work wonders for hydrating the skin and smoothing lines, sometimes our faces need a little extra help. Red light therapy tools, for instance, and other skincare devices can aid with hyperpigmentation, inflammation and toning, but if you're on a budget, a facial roller is also a great option for the latter, especially - and Keira Knightley uses a very luxe-looking but surprisingly affordable one.

With the actress back on our screens with season two of Netflix's Black Doves, we naturally found ourselves wondering about her beauty routine. And after a little digging, we uncovered a standout tool from MZ Skin that she loves for 'toning and lifting' - and refreshingly for a celeb buy, it's under-£60.

Sharing all her favourites with Harper's Bazaar for their 'Inside My Beauty Bag' YouTube series, Knightley revealed that alongside her go-to hair product (Hersheson's Everything Cream) and skin tint (Chanel's Les Beiges Water-Fresh Tint), there's a cooling face roller taking up real estate.

Retrieving it from her bag and showing that it comes with its own handy little carry pouch, Knightley notes that the metallic tool is called 'Tone and Lift', before quipping that that's exactly what she needs it for.

"It's all cold," she said while demonstrating how she rolls the tool upwards along her skin, from her jawline to her cheekbone. "I feel like I'm sculpting my face.

"And you know that bit when you feel like kind of maybe your face is slightly falling, you know, gravity's catching up, you can just go like..." Knightley again shows us how she rolls it upwards along her cheek, "Oh! It's back up again - see, it's magic."

Facial rollers like this one are a good option for lymphatic drainage, much like traditional gua sha tools, and can help with puffiness. This tool especially, can deliver a refreshing, cooling effect, being that it's crafted from germanium and features acupressure pods to stimulate the skin and alleviate puffiness. You can even store it in the fridge for extra icy relief.

And while December is still a little ways off, this tool would make a lovely and fairly inexpensive gift or stocking filler. In fact, Knightley shared that it had actually been given to her by a friend, too, and as we can see, she loves it. So if you're looking for something tried and tested and a little bit luxe, this MZ Skin buy is a good way to go.
