If anyone deserves the "I'm not a regular mom, I'm a cool mom!" mantle, it's Drew Barrymore. And it would figure that the Flower Cosmetics founder would have serious makeup know-how: "I swear by highlighter, but don't put it on over your blush — it'll look murky," advised Barrymore to Redbook. "Instead, pat it just on the tops of your cheekbones, then add a little on the slope of your nose, across your forehead, and a dot on the bow of your lips, then feather out all the edges. It really changes the way your makeup looks."

You might be familiar with Gwyneth Paltrow's penchant for obscure yet luxurious wellness products — especially ever since she launched goop. But there's one big beauty secret she has that doesn't even break the bank: "If you go in in the morning and have had a rough night, dunking your face in ice water is really good," shared Paltrow to Elle. "There are makeup artists sometimes that have a jade face roller. If you're really tired those are really good."

Kerry Washington believes in protection that goes skin deep. She takes SPF very seriously: " I just like to have it be a part of my daily routine. I like to use a foundation that has SPF in it so it just happens. I like to use a moisturizer that has SPF in it year-round, because I think when we create situations where we have to do something different we're less likely to do it," she said in an interview with Vogue.

Supermodel Cindy Crawford has been an icon in the fashion industry for decades. She has even managed to raise two gorgeous children who are also making waves in the modeling world. And Crawford certainly knows where to spend most on the beauty aisle: "Anything that goes on your skin. So skin care and foundation," she shared to Byrdie. "You can get a less expensive mascara, you can get a less expensive lip gloss or nail polish, but anything that's actually on your skin is worth investing in. I don't ever want to look like I'm wearing makeup. I'd rather people be like 'You look great,' or 'Your skin looks great,' not 'Your makeup looks great.'"

Supermodel Kate Moss admits her own daughter knows more about beauty than she does: "She's into natural, organic. Now, she's into mascara and beauty blogs and stuff," she joked to W Magazine. On her own though, Kate practices beauty from inside out by juicing intermittently throughout the year. "At least three times a year, for a week, I do a juice cleanse. I like it. I feel amazing. And then I have so much energy! Everyone else is like, 'Please...shhhh...' Oh my god, I have so much energy start bouncing off walls."
