"I love to use Simple Hydrating Cleansing Oil to remove my face makeup each night. I apply a dime size on the palm of my hand, rub the product over my dry face, and then rinse with warm water. It does a great job removing all of my makeup, while keeping my skin hydrated.

I started using SK-II Facial Treatment Essence two years ago when I started to get more serious with my skin care routine. You use it after your toner, and before your serums and creams. It provides my skin with all the extra nutrients and vitamins it needs, and it gives me a healthy glow.

When it comes to my night creams, I bounce around quite a bit because I'm always looking for the best on the market. I'm currently using antioxidant-rich Jurlique Herbal Recovery Night Cream, and I have to say it's been a very solid night cream for me so far. It hydrates my skin so I look refreshed in the morning, and it doesn't break me out -- making me a very happy girl.

The eye area is very delicate, so an eye cream is an absolute must for me. I love to use the ultra-hydrating Kiehl's Creamy Eye Treatment with Avocado. It's a creamy formula that absorbs nicely, and leaves my eyes looking bright, and my undereye skin vibrant and smooth."

Running a blow-dry bar empire is not for the weak-hearted (or brittle-stranded).

So what does she do to keep her second- or third-day mane looking like she just left the salon? Find out here.

Must-Haves:
"I look for ways to extend my blowout and keep my hair looking its best in between visits. To start, I will not shower without my Dry Divas Shower Cap - there is no better product to keep my hair dry and preserve my style through a shower. It's made from laminated cotton and dries quickly, so it's great for travel.

My go-to hair product for extending the life of my blowout is Unite 7 Seconds Refresher Dry Shampoo. It doesn't leave any residue and gives my hair added volume while also absorbing the oils. I have a travel size that I always take with me when I'm on the go. Plus, I love that their products smell great, and are effective and free from all of the chemicals no one wants.

I always use a satin pillowcase to keep my hair smooth and tangle-free while I sleep. My pick is the Savvy Sleeper -- which also has the added benefit of preventing wrinkles. Who wouldn't want some help with that?

When I absolutely have to wash my own hair (ugh), I wouldn't dream of drying it with a regular towel. Instead, I use Aquis Towels and Turbans, which are designed to reduce frizz-inducing friction and to quickly wick away moisture. It cuts down on drying time and is a real time-saver.

Color Wow Root Cover Up is amazing. I use this root touch-up in between visits to my colorist. It goes on quickly and easily, and stays in place until the next wash."

Building a beauty empire isn't easy an easy task, but the founder of Lanolips, Kristen Carriol, makes it look easy. As a true boss babe, she's constantly traveling for important business, and looking fabulous all the while. So, what's her secret to a flawless face post-flight? Find out here.

"Travelling from Australia, you always have layovers. With layovers, there is always a risk you are going to get stuck somewhere overnight or suitcases are going to get lost when they change planes (this has happened to me many times) -- so, you're stuck at your destination without your packed toiletries bag. When this happens, I rely on these staples I take on the plane. With this lot of goodies, I can look fresh and made up for the next flight, an evening dinner, or that event I'm racing to.

My first must-have is the It Cosmetics Tightline Full Lash Length Mascara Primer. It defines every last single hair but doesn't clump. It gives you a well-groomed, but not too 'made up' look. For an eyeliner, I use the Brow Lash Fix Brown Liquid Liner. This one stays on for hours, won't smudge, and doubles up as a brow filler if you need it. I'll put on a little bit before I land, as it disappears a bit into my lash line and just makes my eyes look more feline, big and awake.

I have a special trick when it comes to my foundation. I used to wear glasses before I had laser eye surgery, and I had all these leftover contact lens cases. Instead of tossing them, I filled one side with my Giorgio Armani Luminous Silk Foundation and the other with my Lano Everywhere Multi-Cream. Together, I have my foundation and allover cream, and I never have to worry about leakage when airborne.

To keep my lips hydrated from the drying plane ride, I turn to my Holy Grail product: Lano 101 Ointment. I slather this onto my lips every few hours and always arrive at my destination with soft, plump lips.

When I have work meetings all day (and need to look human), I carry around the Make Up For Ever Pro Sculpting Face Palette -- as it contains a concealer, a contour cream, a highlighter and a blush. This fab little palette pretty much does all the groundwork on my face once it's moisturized, and leaves my face looking contoured and highlighted in all the right places.

For my signature scent, I like to use Le Soft Perfume Umabel. I love the size of this solid stick perfume, as it's so perfect for travelling. The scent is really light and clean, and has floral undertones with hints of musk and peach. It makes me feel fresh, especially on a crowded plane.

Because planes are especially drying (particularly on long flights from Australia), I like to use the Lano Rose Hand Cream Intense to keep my skin plumped up and to stop it from getting dry and itchy. It's rich and naturally scented with light rose oil. When I need some more moisture on my lips, but I also want subtle color, I'll use the Lano Tinted Balm in Perfect Nude. It's a perfect pink-brown nude that makes your lips glow, but not look crazy pink-red. Plus, the lanolin hydrates at the same time. When I'm traveling, this is the one I use before I go out for the day, every day. I will do a stronger eye and leave the lips nude."

Must-Haves:
"It took me a long time to find a tinted moisturizer that I really love. That is, until I found the Bare Minerals Complexion Rescue Tinted Hydrating Gel Cream. It's basically a tinted moisturizer, BB and CC cream all in one. It's superhydrating, lightweight and has the right amount of coverage to make this full-coverage kinda girl very happy. It's also fast and easy to apply. I just use my fingers and my skin looks instantly healthy and glowy. It's a perfect summer base."

"My lips need a little extra love in the summer and Best Damn Lip Mask is my holy grail lip product (and I'm not just saying that because I created it). This supercharged lip hydrator is perfect year-round for soft, supple and hydrated lips. I apply a little in the daytime for the perfect pink and (slightly) glossy pout. Then I'll slather it on at night to wake up with beyond-hydrated lips.

"When it comes to my summer makeup, it's all about being lightweight. I love the NYX High Definition Photo Concealer. It's a powerful concealer that brightens underneath my eyes, or adds a little extra coverage anywhere I need it. It's very creamy and easy to blend with medium-to-full coverage, but without the heavy feeling. I pair this with Laura Mercier Secret Brightening Powder, which I use to set underneath my eyes. During summer months I like the dewy skin look, so I don't set my skin, but the under-eye area is a must, especially if you want to avoid creasing. This transparent powder really does brighten, and fights all signs of creasing without ever looking heavy.

Sometimes during the summer I can't be bothered to wear false lashes. Enter my favorite mascara of all time: L'Oréal Voluminous Carbon Black Mascara. I'm convinced this volume-building mascara has magic dust sprinkled in it. One eyelash curler plus two coats of this mascara equals no falsies needed.

Is it really a summer look without a summer glow? To achieve my perfect glow, I love using Laura Geller Baked Gelato Swirl Illuminator in Glided Honey. It feels like a cream, but applies like a powder -- creating the perfect amount of glow without overdoing it."

"I love using my Elizabeth Arden Anti-Aging Antioxidant Infusion Essence to help keep my skin looking radiant and healthy throughout the day. Following that, I apply one of my favorite brightening serums from Tata Harper, the Concentrated Brightening Serum, to keep my skin nice and moisturized. To top it off, I always put on a day cream. My go to is the Nivea Q10 Anti-Wrinkle Day Cream with SPF 30.

If you haven't tried Maybelline New York Baby Lips yet, you have to. They're my go-to moisturizing lip balm to help keep my lips supple in the mornings. For color, I like to rock a slight tint to my lips, and I love using Tata Harper's Natural Lip Treatment (tinted), which is also 100 percent natural.

My hands tend to get really dry throughout the day. To help with that I run my OPI Avoplex Cuticle Oil on my nail beds, and then I'll apply one of my favorite hydrating shea butters from L'Occitane to help keep my hands supersoft.

When it comes to my strands, I always leave a few days in between washing my hair. So for the days I don't lather up, I'll use Herbal Essences Naked Dry Shampoo to keep my hair fresh and clean."
