Supermodel skincare secrets

Skincare:  Crawford told InStyle that, "I think people always want that quick fix, but to me it's about consistency. I didn't just start working out; I began when I was 20. Working out, getting enough sleep, not smoking—all of these things are cumulative. You may not see those results in a week or even a month, but in a year, and with consistency, you will. It's about maintenance. That's my approach on how to handle ageing."

Hair: In 2016, she said, "I'm trying to be kinder to my hair and not heat style it so much."

Diet: According to Stylist, Crawford's one diet tip is "don't yo-yo diet. [Skincare expert Dr Jean-Louis Sebagh] taught me to pick a weight and stay there. It's not good for your skin to stretch, contract, stretch, contract. I try not to have empty calories, though I do have chocolate every day. That's worth it to me."

Exercise: "Over 20 years ago, I saw a woman doing exercises for her neck," she told Into The Gloss. "She explained that if you keep those muscles toned, it helps preserve the line of your jaw. They're simple to do—just lay flat on your back with your chin pointed up, and lift your whole head about an inch off the ground. Without putting your head back down on the floor, bring your chin to your chest. I do three sets of 10 repetitions, but you can build up to that!"

Skincare: In an interview with Allure Christensen revealed, "My grandmother has the most beautiful, softest skin. And all she ever uses is water, soap, and Nivea. Over the years, I've used hundreds of different products, amazing-smelling oils, scrubs, and serums. But every time I visit my grandma, I go back to the soap, the water, and the Nivea." She also keeps her make-up look pretty simple too, telling Red that, "I just do a little
 blush and some gloss on my lids or smudge in some eyeliner – but that's it."

Hair: She told Red that, "Harry Josh and Owen Gould cut my hair and I always ask them to trim the sides into a choppy style. Then I'll wear it in a loose bun or braids for the day or wavy in the evening."

Diet: Her one tip is to "eat healthily all year round - find an exercise you enjoy and drink lots of water or coconut juice."

Exercise: "I used to wake up in the morning and sprint, which is a great way to spark your metabolism and get your brain tuned up. And in my mid-30s, I started boxing. My newest exercise is pole dancing, and it's the hardest thing I've ever done. The upper-body strength you need to carry out any of the moves is mind-blowing."

Skincare: "It's all about exfoliation. My favourite is Clinique for Men face scrub, because it has enough grittiness to actually make a difference and gives skin a refreshing tingle. I use it at least two-to-three times a week. If I need some extra love, I'll use CellCosmet Anti-Stress Mask afterwards to make my face glow."

Hair: In an interview with Byrdie, Schiffer said "I use Schwarzkopf Essence Ultime Lotus Blossom + Colour Protect in the shower to make my hair colour last, whilst also giving it a really healthy look." She also revealed to Glamour that she's "a wear-my-hair-down kind of woman, but I don't like when it's over-styled, so I stop blow-drying my hair when it's still slightly damp and let it air-dry the rest of the way. It makes it more lived-in and not so perfect."

Diet: The Daily Mail quoted Schiffer as saying "I am all about health, rather than diet. For example, I eat less dairy and less gluten when trying to be healthy. I find this works way better than totally cutting things out."

Exercise:  The supermodel also told Byrdie that she works out "by doing long walks with the dogs, tennis, yoga or Pilates".
