Keira Knightley is a busy jet-setting actress with little time to care for her complexion. But, instead of spending a small fortune on top-shelf products, this English rose keeps her skin glowing with what some call the holy grail of skincare, affordable Rosehip Oil.

“I completely fail to keep myself on an even keel with my skincare when travelling, but I have just discovered Rosehip Oil, which a friend of mine recommended,” the actress recently told British Vogue. “Flights are so hard on your skin and they make it so dry, so I gave this a go and it really worked. Now I always travel with it.”

Speaking with Beauty Banter recently, Meghan Markle spilled on the beauty products she uses to achieve that infamous ‘Markle sparkle’, and lucky for us, they’re budget buys you can find at the chemist.

When it comes to keeping her skin hydrated, the Suits actress revealed she uses Nivea’s $11/400ml, Firming Body Lotion Q10 Plus“religiously”. The American beauty added: “It’s honestly my favourite lotion on the market, it’s so affordable, and makes my skin look and feel amazing. I would buy a case of this at a time if I could find it.”

Also in her beauty bag are Biore Daily Deep Cleansing Wipes which Meghan says she keeps beside her bed for “those horribly lazy nights that the thought of getting up to actually wash your face seems unbearable.”

During her press tour for Beauty and the Beast, Emma Watson opted for natural and cruelty-free beauty brands including Sukin’s Hydrating Mist Toner which is only $15.90.

When Duchess Kate caught up with then-First Lady Michelle Obama, she shared a few beauty tips. Kate recommended Biotulin Supreme Skin Gel – which is a natural alternative to Botox – as well as the her favourite eyeshadows – the cult Naked Palette.

Self-confessed beauty junkie Drew Barrymore cannot get enough of Klorane Gentle Dry Shampoo. “If you are trying to preserve a blow dry or just like slept-in hair, this is the best dry shampoo. Poof and marvel. Spray in at roots and then comb out with a thick brush,” she wrote on her Instagram review, praising the product.

Drew discovered another beauty product after a trip to Korea. “I just took a trip there and came back with moving boxes full of masks,” she told Us Weekly. “I don’t do anything invasive on my face, so this is the most exciting thing that’s happened to a mum like me. I was feeling 41 and tired, and I need something and the Korean masks have actually changed my life.”

Like us, Olivia Wilde takes a no-fuss approach to beauty. “I use the cheapest possible skin care — not because it’s cheap, but because it’s the best,” she told Popsugar. “Dermatologists have recommended it for years and I’ve never paid attention. But recently I started using Cetaphil cleanser and CeraVe moisturizer. They’re gentle and simple.”

Beauty chameleon Nicole Kidman is all about a space-saving, multi-purpose product these days. “I’m a mum, so I don’t have a lot of room in my bag, but I always try to have an all-in-one product. I use Benefit Benetint on my lips and cheeks,” she told Allure.

Benefit Benetint Rose and Cheek Stain, $57.

Star of La La Land, Emma Stone has sensitive skin so has to pick her prods wisely. “I’m really allergic to a lot of stuff, so I can really only use products with one thing in them,” she told Style Caster. “So I use Burt’s Bees cleanser.”

Gwyneth Paltrow is known for her wild and slightly unattainable natural beauty standards but she actually does use more products than her own natural skincare line, Goop. For foundation (organic, of course) she turns to a nifty tool to get a flawless finish: “With the foundation I use one of those little Beautyblenders.” she tells IntoTheGloss. “My daughter gave it to me—she’s very into beauty products.”

When it comes to details, Victoria Beckham keeps things simple but well, posh. “I love CND’s Shellac Nude Knickers, which goes with everything and lasts for ages,” she told The Telegraph.
