This past summer, I booked a plane ticket to Los Angeles with the hope of investigating what seems likely to be one of the oddest legacies of our rapidly expiring decade: the gradual emergence, among professionally beautiful women, of a single, cyborgian face. It’s a young face, of course, with poreless skin and plump, high cheekbones. It has catlike eyes and long, cartoonish lashes; it has a small, neat nose and full, lush lips. It looks at you coyly but blankly, as if its owner has taken half a Klonopin and is considering asking you for a private-jet ride to Coachella. The face is distinctly white but ambiguously ethnic—it suggests a National Geographic composite illustrating what Americans will look like in 2050, if every American of the future were to be a direct descendant of Kim Kardashian West, Bella Hadid, Emily Ratajkowski, and Kendall Jenner (who looks exactly like Emily Ratajkowski). “It’s like a sexy . . . baby . . . tiger,” Cara Craig, a high-end New York colorist, observed to me recently. The celebrity makeup artist Colby Smith told me, “It’s Instagram Face, duh. It’s like an unrealistic sculpture. Volume on volume. A face that looks like it’s made out of clay.”

Instagram, which launched as the decade was just beginning, in October, 2010, has its own aesthetic language: the ideal image is always the one that instantly pops on a phone screen. The aesthetic is also marked by a familiar human aspiration, previously best documented in wedding photography, toward a generic sameness. Accounts such as Insta Repeat illustrate the platform’s monotony by posting grids of indistinguishable photos posted by different users—a person in a yellow raincoat standing at the base of a waterfall, or a hand holding up a bright fall leaf. Some things just perform well.

The human body is an unusual sort of Instagram subject: it can be adjusted, with the right kind of effort, to perform better and better over time. Art directors at magazines have long edited photos of celebrities to better match unrealistic beauty standards; now you can do that to pictures of yourself with just a few taps on your phone. Snapchat, which launched in 2011 and was originally known as a purveyor of disappearing messages, has maintained its user base in large part by providing photo filters, some of which allow you to become intimately familiar with what your face would look like if it were ten-per-cent more conventionally attractive—if it were thinner, or had smoother skin, larger eyes, fuller lips. Instagram has added an array of flattering selfie filters to its Stories feature. FaceTune, which was released in 2013 and promises to help you “wow your friends with every selfie,” enables even more precision. A number of Instagram accounts are dedicated to identifying the tweaks that celebrities make to their features with photo-editing apps. Celeb Face, which has more than a million followers, posts photos from the accounts of celebrities, adding arrows to spotlight signs of careless FaceTuning. Follow Celeb Face for a month, and this constant perfecting process begins to seem both mundane and pathological. You get the feeling that these women, or their assistants, alter photos out of a simple defensive reflex, as if FaceTuning your jawline were the Instagram equivalent of checking your eyeliner in the bathroom of the bar.

“I think ninety-five per cent of the most-followed people on Instagram use FaceTune, easily,” Smith told me. “And I would say that ninety-five per cent of these people have also had some sort of cosmetic procedure. You can see things getting trendy—like, everyone’s getting brow lifts via Botox now. Kylie Jenner didn’t used to have that sort of space around her eyelids, but now she does.”

Twenty years ago, plastic surgery was a fairly dramatic intervention: expensive, invasive, permanent, and, often, risky. But, in 2002, the Food and Drug Administration approved Botox for use in preventing wrinkles; a few years later, it approved hyaluronic-acid fillers, such as Juvéderm and Restylane, which at first filled in fine lines and wrinkles and now can be used to restructure jawlines, noses, and cheeks. These procedures last for six months to a year and aren’t nearly as expensive as surgery. (The average price per syringe of filler is six hundred and eighty-three dollars.) You can go get Botox and then head right back to the office.

A class of celebrity plastic surgeons has emerged on Instagram, posting time-lapse videos of injection procedures and before-and-after photos, which receive hundreds of thousands of views and likes. According to the American Society of Plastic Surgeons, Americans received more than seven million neurotoxin injections in 2018, and more than two and a half million filler injections. That year, Americans spent $16.5 billion on cosmetic surgery; ninety-two per cent of these procedures were performed on women. Thanks to injectables, cosmetic procedures are no longer just for people who want huge changes, or who are deep in battle with the aging process—they’re for millennials, or even, in rarefied cases, members of Gen Z. Kylie Jenner, who was born in 1997, spoke on her reality-TV show “Life of Kylie” about wanting to get lip fillers after a boy commented on her small lips when she was fifteen.

Ideals of female beauty that can only be met through painful processes of physical manipulation have always been with us, from tiny feet in imperial China to wasp waists in nineteenth-century Europe. But contemporary systems of continual visual self-broadcasting—reality TV, social media—have created new disciplines of continual visual self-improvement. Social media has supercharged the propensity to regard one’s personal identity as a potential source of profit—and, especially for young women, to regard one’s body this way, too. In October, Instagram announced that it would be removing “all effects associated with plastic surgery” from its filter arsenal, but this appears to mean all effects explicitly associated with plastic surgery, such as the ones called “Plastica” and “Fix Me.” Filters that give you Instagram Face will remain. For those born with assets—natural assets, capital assets, or both—it can seem sensible, even automatic, to think of your body the way that a McKinsey consultant would think about a corporation: identify underperforming sectors and remake them, discard whatever doesn’t increase profits and reorient the business toward whatever does.

Smith first started noticing the encroachment of Instagram Face about five years ago, “when the lip fillers started,” he said. “I’d do someone’s makeup and notice that there were no wrinkles in the lips at all. Every lipstick would go on so smooth.” It has made his job easier, he noted, archly. “My job used to be to make people look like that, but now people come to me already looking like that, because they’re surgically enhanced. It’s great. We used to have to contour you to give you those cheeks, but now you just went out and got them.”

There was something strange, I said, about the racial aspect of Instagram Face—it was as if the algorithmic tendency to flatten everything into a composite of greatest hits had resulted in a beauty ideal that favored white women capable of manufacturing a look of rootless exoticism. “Absolutely,” Smith said. “We’re talking an overly tan skin tone, a South Asian influence with the brows and eye shape, an African-American influence with the lips, a Caucasian influence with the nose, a cheek structure that is predominantly Native American and Middle Eastern.” Did Smith think that Instagram Face was actually making people look better? He did. “People are absolutely getting prettier,” he said. “The world is so visual right now, and it’s only getting more visual, and people want to upgrade the way they relate to it.”
