Throughout your teens and twenties, it's pretty easy to live in a suspended reality - one where you never get old or need to spend much time thinking about 401Ks, mammograms, or renewing your license. You don't need me to tell you: that ends.

We wanted Glossier to have an excellent customer experience and reach as many of you as possible from day one, so we went with venture - the stuff fast-growth, tech-enabled companies like Facebook, Amazon, and Apple are made of.

Where Halloween is concerned, I peaked in 2007.

For some, Into The Gloss is just a blog, and that's cool. For us, it's the connective tissue between us and you, and that has paved the way for the creation of a very different kind of beauty brand: Glossier.

What no one tells you - or maybe they did tell me, and I chose not to listen - is that there's really no 'coming back' from bleached platinum hair. You sort of have to cut it all off and start over.

Women are truly, truly awesome.

I would rather be 'oily' than 'dry' on pretty much any part of my body.

I've never been one for color theory or color wheels or undertone rules or anything like that. I don't know if my red lipstick 'should' be more blue or more orange.

The guardians of French pharmacies - the lab-coated salespeople - are busy, serious, and probably know more about your face than you do. Therefore, don't interrupt them, and if they ask you if they can help you, for God's sake, let them. They will not steer you wrong.

Augmenting your appearance so drastically that it elicits a reaction from literally every acquaintance you greet is a sea change.

In my humble opinion, having tons of products and furniture and magazines and clothes is not luxurious - living minimally is.

Elin Kling is one of the most stylish women I know.

At Glossier, we're creating an edited collection of the best essential products. These are the ones that you reach for every day and will always have a place on your top shelf.

I am crazy for good branding and really admire companies that get it right.

That power of the individual person - just the girl - is infinite.

I love someone with something to prove.

I don't even need to know - if you have something to prove to your old boss or your dad or your third grade teacher or yourself, it doesn't matter. You need that hustle and that fire, and I don't care where it comes from.

We're trying to create one holistic beauty experience where you can be inspired by other women, both the people we're interviewing and the community contributing to the conversation.

Glossier is really for anyone who wants to embrace the present and live in the now. It's about embracing constant change and who you are at any given moment, and that's often someone who's imperfect - and that's cool.

We want to demystify and present things in real talk. That's why Into the Gloss struck a nerve. Glossier is not much different. We're providing this rich environment around products that help consumers understand their benefit.

If you're interested in a 'Teen Vogue' internship, take note: it's not all fun and games! Working at a magazine requires a ton of energy and endurance from its interns and editors alike.

We're not telling you that you need a concealer. We're providing a concealer in case you want it. We're trying to give you the tools to be able to make whatever decision you want.

I approached fundraising as an opportunity to align myself with partners who have more varied experience and diverse backgrounds than I do to help bring Glossier to life.

I always thought 'Into The Gloss' would be successful, but I didn't really know what my definition of success was.

With 'Into The Gloss' and now Glossier, the reason it was successful was because there were so many like-minded women out there who were also dissatisfied with their beauty experiences.

I think reality television has made the fashion industry and the beauty industry, any industry - frankly, just life - it has made life seem much different than it really is.

I eat out alone a lot.

We incorporate a lot of natural ingredients into our Glossier products, like sweet almond oil, which is great at getting moisture deep into the skin.

I grew up in a conservative New England town and showed up to my middle school orientation dressed like 'Clueless' while everyone else was wearing J. Crew and lacrosse uniforms. I never really fit into that preppy look.

I like to get rid of things; I don't collect many things. But I do keep great photography and art books.

I feel like I have time to think when I'm in L.A. There's something about the spaciousness of it.

Glossier is not about throwing out everything you're using. If you want to keep using your retinols, your SPFs, of course you should continue.

When your lips get dry, is there anything more frantic?

Everyone says to hydrate on the plane, but I don't.

If you look dull, the easiest thing to do is wash your face with water, and immediately you look refreshed.

It's very important to me to have a female venture capitalist.

I'm on Instagram more than any other social platform.

You don't need most beauty products. They're an emotional purchase. That's why the conversations are really important. What choice do you have but to ask your customer what they want?

Making a bougie, expensive beauty brand wasn't helping the mission or very fun for me. We can all be united by that $12 coconut balm. You don't need to charge an arm and a leg.

We could be like a lot of consumer brands that start blogs after they start their business. But in our case, I think Glossier is still very much a content company. I think about our products themselves as pieces of content.

Ultimately, we're making and selling a consumer good that needs to work and that needs to make customers happy.

In our product development cycle, we ask and listen to our customer about what she wants.

Beauty is very intimate.

One of the big things I've learned over the years and I'm excited that Glossier perpetuates is that wherever you're at, in terms of your scope of knowledge around beauty, is totally okay. And not just okay, but actually really valuable.

I've had such an inspiring and formative journey in my career.

I just have to stop biting my nails. I've been on and off that bandwagon so many times. I feel like it's going to be a lifelong struggle.

You learn a lot about people when you're sitting on their bathroom floor or on their toilet seat, rifling through their stuff.

I love supporting female-owned companies and women who are awesome.

There's so much pressure on women to have it all together. There's always this 'next, next, next.' I hope Glossier encourages women to be O.K. wherever you are. Just, everyone, relax!

I'm surrounded by women whose style I admire. It's natural to be inspired. I'm not a horrible copycat, or if I am, then I admit it and make a joke about it.
