I've just landed in New York City for the weekend to visit my best friend. I'm standing outside Terminal 5 at JFK, wearing fuchsia lipstick and blue eyeglasses, and I want my 391 Instagram followers to know I've arrived. I hold up my iPhone, grin sideways and snap. Approve, filter, post.

I turn around to see a middle-aged man in a scarf roll his eyes at me and shake his head. He thinks my selfie is frivolous. The product of a generation hooked on social media, full of people who all think they deserve to be famous. I'm slightly embarrassed that he's caught me in this moment -- it's weird to see someone see you take a selfie -- but this is not about vanity.

Over the past three or four years, selfies have come to pervade our culture. There have been songs and TV shows written in their honor, tools manufactured to facilitate their taking. For those of us who didn't grow up with iPhones and social media, it's easy to sit in judgment of the selfie. We tend to think girls who take too many are self-obsessed and attention-seeking. What happened to modesty? we wonder.

But recently, more complex theories about the selfie have arisen, particularly in regard to its portrayal of women. "Selfies are one way for a female to make space for herself in the world: To say 'I'm here, this is what I actually look like, my story counts, too,'" says Pamela Grossman, director of visual trends at Getty Images. "They allow girls to shine on their own terms."

So even if you've written off selfies forever, try to push through the following ten. These images show the ways in which instant self-portraits can empower us. They might even inspire you to dust off that front-facing camera.

In magazines, "Girls" creator Lena Dunham is dressed up, photographed and airbrushed by professionals, and her words are carefully edited. But on social media, she's able to share her authentic self. The pose, the clothes, the message -- they all come straight from her.

Accompanying this Olympian fitness stance, Dunham says, "Promised myself I would not let exercise be the first thing to go by the wayside when I got busy with 'Girls' season 5, and here is why: It has helped with my anxiety in ways I never dreamed possible. To those struggling with anxiety, OCD, depression: I know it's mad annoying when people tell you to exercise, and it took me about 16 medicated years to listen. I'm glad I did. It ain't about the ass, it's about the brain."

Model Cara Delevingne and actress Margot Robbie are paid to look sexy, and without selfies like this, we'd only ever see them through that lens. "Selfies open up deep issues about who controls the image of women," says Peggy Phelan, PhD, a faculty fellow in the Clayman Instutite for Gender Research at Stanford University. They give girls the chance to reveal a goofy, imperfect, human side of themselves that we might not otherwise see.

Selfies aren't just about putting your best duck face or contoured makeup on display. Here, actress Amandla Stenberg (of "Hunger Games" fame) shares a snapshot of her friends getting their study on. Her caption reads, "when u & the squad [are] reading surrealist feminist fiction." It's selfies like this that help girls build an identity and inspire others to share their own truth.

We're taught that zits, freckles and cellulite are the devil, but with a single selfie, magazine editor Tavi Gevinson shows that all you need is a little humor to take the edge off. Flaunting her epicurean wit, while rejecting unreasonable beauty standards, she captions: "Highly recommend the new Yayoi Kusama they just installed on the Upper West Side of my face."
