I love how Drew speaks candidly about her favorite things related to beauty, how she feels about her body post babies and more with Glamour!

Drew Barrymore, star of the upcoming film Miss You Already—and creator of Flower Beauty—shares her personal truths.

Her favorite feature: My hair. It takes a licking and keeps on ticking. I destroy it time and time again, and it’s still there, semi-happy. I love playing with it; it’s like my personal plant—I keep getting to prune it.

Her favorite look on a man: I love beards. They’re the sexiest. But I will say that under no circumstances is a goatee OK. And soul patches are insanity! What is that all about?

Her signature look: I feel perfect when I match my cheeks to my lips. It brightens up my whole face, that monochromatic color splash.

Her body wisdom: After making two babies, holy cow, does your body do some crazy stuff! It’s hard to stay positive and love yourself. You feel like a kangaroo with a giant pouch; everything’s saggy and weird. But you think about how beautiful it is that you’re able to make children. When I lose sight of that, I exercise, read Dr. Seuss’s Oh, the Places You’ll Go!, and spend time with my kids. Then I start to see things that are bigger than myself.

Her desert-island essentials: I’m lost without Aquaphor Healing Ointment [$8, at drugstores], as lip balm and for every other odd emergency. I’ll give anything not to have a zit, including buying Christine Chin’s Hydrating Toner [$28, christinechin.com].

Her selfie secret: You don’t always have to look stunning on Instagram. I’ve been makeupless, pregnant, and stuffing food in my face in many pictures; that makes it all the more exciting when I do do something more attractive. I don’t like it when everyone looks so perfect all the time. Where’s the humor in that?

Her Signature Scent: “It’s inspired by the morning and that light that pours into your windows. A beautiful chaos of vanilla, lemon, and cabbage rose.” Flower Cherished Fragrance eau de parfum ($25 for 1 oz., walmart.com)

Her Proudest Product Creation: “It’s a rollerball concealer you can use under the eyes or on sun damage. It’s awesome: It gives great coverage and works on everyone.” Flower D.B. Daily Brightening Undereye Cover Creme ($9, walmart.com)

Her Favorite Makeup Look: “I love a bright lip and bright eyeshadow. Just don’t throw a ton of liner or mascara on top, and it can still look clean.” CoverGirl Colorlicious Lipstick in Tempt Berry ($7, ulta.com)

Her Boldest Beauty Move: “I found this photo of myself [from 2003] with burgundy lips and canary yellow shadow, which was all over my lids and possibly past my brows! It was very hard to pull off, but I’m glad I rocked it.” Make Up for Ever Artist Shadow in #S-402 ($21, sephora.com)

Drew shared with Marie Claire some of her best beauty tips!

You know that beauty myth that guys hate a red lip? Drew Barrymore is here to tell you it’s not true. And if you’re still hesitant, she has a few suggestions. (PSA: We should all be subscribing to the Barrymore Beauty Bible.)

There are many things we’d love to bend Drew Barrymore’s ear about. There’s style, which she’s got in spades. There’s music—she has immaculate taste and has even penned lyrics for fellow cool girl Jenny Lewis. There’s boys, because she taught us a sacred lesson: He’s just not that into you. And then there are the tall tales that come with being a Hollywood star for over three decades…

But still, if we could only choose one topic for a Barrymore heart-to-heart, it’d be beauty. With her line Flower Beauty, she’s not only brought luxe and affordable botanical-infused products to the masses, but has done so with a fun, real-girl MO that’s just so refreshing. Whether she’s painting her nails on the subway (#commuterbeauty), easing our mind about our product-hoarding tendencies, or waxing poetic about the perfect shade of red, she just gets us.

In advance of launching her Spring 2015 collection, we chatted with Barrymore about her tried-and-true beauty tricks, handbag essentials, and hacks for doing your makeup en route.

Marie Claire: What are your most sacred beauty secrets?
Drew Barrymore: 1) Eye brightening! Undereye concealer just isn’t enough, so we created a brightening primer (Flower Lighten Up! Brightening Concealer Click Pen, $7.98). Instead of try to patch-up a dark spot, brighten it. Reflect out. Stop covering it up!

2) Brows are everything. I’ve started working from a kit rather than a pencil because it’s not just one color all year long for me. If I’m wearing a dark lip, I want light brows. If I’m wearing a light lip, I want dark brows. I also change the color of my hair, and that changes what color I want for my eyebrows. Plus, it has a taming wax I love because it makes brows dewy without being greasy.

3) My biggest criteria is lips that don’t feather. Whether it’s a lip balm, lacquer, or a stick, an anti-feathering formula is what I want and what I put in the line. It’s the most expensive from a lab perspective because it works better. It’s so important to have that experience for your lipstick.

MC: What skincare ritual do you swear by?
DB: Washing your face morning, noon, and night—most especially after those long nights. Fall asleep with your makeup on and you’ll wake up doomed is my philosophy.

MC: When it comes to carrying around products in your purse, are you a minimalist or a hoarder? We’re totally the latter.
DB: I hate a heavy bag because I carried one around for 40 years, and now I’m trying to lighten it up. And now I have a diaper bag, so that changes everything… But I always have a dark and nude lip, a concealer and a powder, and something for the eye, whether it’s an eyeliner or a mascara. What it really comes down to is something for eye, lips, and face. You can really get away with three things, but I like to double up and have the opposite sides of the spectrum for each product.

MC: We love and can seriously relate to your #commuterbeauty hashtag—what’re your best tips for beauty on the go?
DB: Just today I did my mascara in the rearview mirror of an Uber going to my next appointment. So a rearview mirror is really great—but only if you’re a passenger. You cannot do it as a driver. [Laughs] Safety first!

I think the most important thing for commuter beauty is finding innovative ways to find a reflection that you can do your makeup in. So, think the window of a subway or a spoon at a dinner table. I always judge a restaurant by whether or not they have a clean knife because it’s the best mirror.

MC: And what about painting on a cat eye in a moving vehicle—that’s kind of our thing…
DB: Wait for the stop!

MC: Your February 2014 MC cover got nominated for a National Magazine Award! What set it apart from other cover shoots you’ve done?
DB: You know, having a beauty company, I love tight shots on a cover. And I think people love it too. It’s so eye-grabbing and yet magazines are doing it less and less. So I applaud Marie Claire because we really pushed for it as we wanted it to be about the beauty.

MC: And remind us what smashing Flower shade you were wearing on the cover?
DB: Rose Bud!

People did a style feature on Drew and her three new fragrances she is launching for Flower Beauty!

When we had the opportunity to sit down with Drew Barrymore, actress, PEOPLE guest beauty editor and founder of the successful beauty (and now fragrance!) brand, Flower Beauty, we found that the well-known star can still surprise us. See why she’s enamored of the scent of whale vomit (yes, you read that correctly), what beauty move she can do with her eyes closed and more.

Before Barrymore launched her three new fragrances — Cherished, Radiant and Sultry — she spent hours in the lab trying out different scents, which led to her falling in love with quite an unusual smell: whale vomit (also known as ambergris). “When a whale would eat squid, I believe they would digest [it] in the whale’s stomach, and the whale would throw it up out and everything that was in his stomach to break down the squid,” she says. “It has this most potent, amazing, knee-buckling scent to women. I became voracious, I was like, ‘I want it! I need more!’ I kept grabbing it and smelling it like a little piglet.”

In case you were wondering (slash panicking), there’s no whale vomit in Barrymore’s fragrances. “Now they’ve decided to do a molecular copy of [ambergris] because they don’t want to hurt whales and take from whales anymore, thank God for that,” she shared. “And it’s in some of the best perfumes out there. That was cool to learn. I loved me some ambergris.”

In addition to being able to identify the smell of nauseous whales, the beauty mogul has another hidden talent: applying lipstick with her eyes closed à la Molly Ringwald in The Breakfast Club. Well, maybe not quite like Ringwald in the iconic scene (you know, the one where she applies lipstick without her hands), but she’s close! “Didn’t we all try to attempt the lipstick between the … When she did that trick, you were like, ‘Oh, you’re so cool.’” she says. “Not that I do that, but I think I could do lipstick with my eyes closed or anywhere,” she tells PEOPLE.

And to prove her point, she’s committed to the concept of “commuter beauty,” which she loves to share her Instagram. “I don’t remember the last time I sat down and did my makeup. It’s always on the go,” Barrymore says. “I want to see women putting their pictures out there of [their] on the go. That excites me. That would be my first thing, my #commuterbeauty hashtag that I am obsessed with, because it’s so true!”

But even though Barrymore is a pro at doing all her makeup on the go and mirror-free, she doesn’t run her beauty empire alone. She often asks friends and family — even her husband, Will Kopelman — for input on the collection! “I ask my husband his thoughts because he comes from an amazing family — he’s so smart, so chic and he has amazing taste,” she tells PEOPLE. “And I ask his family and I ask my friends. I like to get people’s opinions on things. I think you always have to trust your gut, ’cause that’s all we have, but it’s really good and crucial to get opinions.”
