Equally I type these words, my nails are 10 minor silver mirrors, reflecting the overhead fluorescent lights as I move my fingers across my keyboard. I learned about these so-chosen chrome nails from The Atlantic's fashionable deputy web editor Swati Sharma, and shortly thereafter, she and I went and got manicures so I could meet the process in activity. The mirror effect was created with a special powder that a blast technician, every bit they're referred to in the manufacture, rubbed onto a layer of polish with a tiny sponge. It was mesmerizing, and a little mystifying. How did the glitter powder transform into a solid, shiny surface?

We accept the ruby-red-carpeting mani cam to thank, at least partially, for the surge in popularity of smash art, says Beth Livesay, the executive editor of Nails mag. When celebrities started treating their nails as canvases for miniature art, the trend caught on with the public, besides. But lately, the boom-art galleries of Pinterest and Instagram have been displaying not just polish hand-paintings, merely futuristic-looking furnishings like chromes, cat'due south eyes, and holographic rainbow nails.

"Right now, the trends are the furnishings," Livesay says. "The bar's been raised universally for nail art."

I spoke with a couple cosmetic chemists to sympathise the science backside turning normal human nails into mirrors, or gemstones, or shimmering fish scales. They explained the basic chemical processes behind polishes and effects. (I can't, yet, confirm the exact ingredients of many specific brands' products. I reached out to OPI, Orly, Artistic Nail Design, and Whats Upwards Nails—all of which declined to be interviewed or did not render requests for comment.)

It starts with understanding how regular nail polish works, and how the longer-lasting "gel" manicures are dissimilar. Regular polish, or "lacquer" every bit some in the industry call it, is made of polymers—long chain molecules that are skilful at forming strong structures—dissolved in solvents. Once the polish is painted on, the solvents evaporate, leaving behind the film formed by the polymers (and the pigment that gives it colour). Lacquers too oftentimes include other resins and plasticizers to help the smooth attach to the nail, and to brand it more flexible. To remove it, you employ a solvent in the form of nail-smoothen remover (typically containing acetone or ethyl acetate), and the lacquer dissolves.

"It's very much similar hair spray," says Doug Schoon, the president of Schoon Scientific and a onetime chief scientist at a commercial blast-shine company. "You spray it on your pilus, the solvent evaporates off, and information technology leaves a coating that holds the hair in identify. Nail smoothen is a little more sophisticated than pilus spray, considering hair spray only has to do one thing, and really doesn't final that long, whereas nail polish has to be shiny, adhere to the nail plate, exist resistant to scratching and dings, hold the color and not fade, and come up off easily when you desire it."

Gels—which Livesay says also helped fuel the showtime of the nail-art craze—are longer-lasting substances that are generally available in salons, and which harden under UV or LED light. Whereas the picture show-forming polymers are already mixed into your standard boom lacquer, "in the instance of artificial nail coatings, they're really making the polymer on the boom," Schoon says. "The gels are oligomers and monomers, which are snippets of polymers, and so when the UV calorie-free hits [the gel], information technology causes these snippets to all join together and assemble similar a jigsaw puzzle."

What happens under the lamp is a costless-radical reaction, "which sounds actually rebellious," says Jim McConnell, a pharmacist and the cofounder of Lite Elegance, a smash-product company. The light causes a chemical compound in the gel to release a very reactive molecule known every bit a free radical, which so attacks and opens upwards bonds within the monomers and oligomers. Those bonds are then free to re-form with side by side molecules into a more intricate chain, creating the hard polymer that makes the gel manicure and so durable and long-lasting.

Confusingly, though, a lot of different products are called "gels." "It's a struggle constantly to become the right terminology in place," Livesay says. "A lot of times people don't know what they're asking for."

There are hard gels, which are the nigh durable, and can only be removed past filing them off. These are more pop in Europe, according to McConnell. Soft gels are similar, but slightly less durable and easier to remove. And then at that place are gel polishes, which are more probable to exist what the average American will encounter if they just walk into a salon and enquire for a "gel manicure." The composition of these tin can vary depending on the make—some are soft gels mixed with solvent; some are gels mixed with lacquer. Both tin can be removed with acetone.

(A word of caution from Schoon: With any sort of gel, a technician should never file information technology off all the way down to your natural smash. "This is similar putting a bunch of glue on your roof and and so taking a crow bar and scraping the glue off. You're going to pull shingles up, besides.")

Gel manicures form the base for a lot of the visual effects that take populated social media of late. "Outcome powders" are responsible for the chrome look, equally well as the holographic nails. These powders, McConnell says, all piece of work in pretty much the same way, but are just made with different materials. Afterwards a boom technician paints on a layer of gel color, they cover it in a special top glaze, and cure it under a lamp but long enough for it to be barely sticky. Then they dip the petty sponge in ane of these powders, and rub it in.

For chrome nails, that pulverisation is made of glass, metal, and paint. "There's no chrome in information technology," McConnell says. "That would be completely illegal, because chrome is a heavy metal and the FDA would be downward our throats almost it. It'south more of a mirror nail." And much similar with a existent mirror, the reflective upshot is created when a metallic—silver, in this example—is sandwiched between a base layer of paint (or smoothen in this case) and a clear protective layer on top (glass for a mirror; a clear, glossy smoothen for the chrome nails).

The powder doesn't become a solid, even though information technology looks like information technology does; it's only extremely fine and fills in extremely well. "If you could magnify it really, really big, y'all could run into there'south spaces between each of the particles," Schoon says, "but you tin can't encounter it with your center, because they're too tiny."

Dissimilar effects can exist achieved with different pigments. Light Elegance has a agglomeration of dissimilar Pretty Powders, some of which requite a chrome consequence, some of which are pearly—that comes from mica coated with paint, McConnell says—and some of which are holographic. The holographic effect (also sometimes called mermaid boom) is fabricated with extremely fine $.25 of holographic polyester. This look can also be achieved, Schoon says, with a thin polyester motion-picture show, "like the ribbons they wrap presents in at Christmastime." But Lite Elegance, at least, sells that polyester in a powder form that can be rubbed on the aforementioned every bit a chrome.

Tiny particles are too responsible for the true cat'south-eye effect—just they're incorporated into the polish itself, rather than spread on tiptop as a powder. A polish formulated with fe oxide is painted onto the blast, and and then the technician will hold a magnet over it. "It'south like the old Etch a Sketches," Schoon says. "All the iron particles volition line upward, carry the pigments with them, and create a special effect." The rearranging leaves a lighter stripe in the polish, which looks similar the ring of light in a true cat'south-center gemstone.

"Dip powder" manicures are nonetheless another trend, and they're exactly what they sound similar: The color is applied past dipping the finger into a trivial pot of acrylic powder. Information technology sticks because the base coat is basically corrective-form superglue. Then you tin repeat the process for every bit many layers of color as you want, and seal with a topcoat.

"All the brands are coming out with [dip pulverisation] now," Livesay says—simply these products have been around since the 1980s. None of this chemistry, Schoon and McConnell stress, is peculiarly new. Effect powders are the newest, having hitting the market a couple years ago, they say, but Schoon characterizes all these furnishings as but creative uses of old pigments and ingredients.

And these effects are particularly social-media friendly. Not just do they wait absurd when they're done, but the process of applying a chrome powder or a dip powder or holding the magnet to a cat's-eye smooth is fun to lookout man, and makes for a good YouTube or Instagram video.

"Information technology'south a very soothing process to sentinel," Livesay says. "You know how on Instagram, it recommends videos for you lot, and 'oddly satisfying' is i of the [hashtags]? It's like people frosting a block or something like that? I think it's the aforementioned thing. I think it seeps into where our culture is at correct now: It's quick, it's kind of mindless, but also it's very comforting."
