The Best Beauty Products of 2015

The new (super-easy) statement eye for summer: a sweep of bright turquoise along the lower lash line. Makeup artist Grace Lee promises that even a Day-Glo blue works "on every skin tone and eye color." She used an angled brush to blend Maybelline Color Tattoo gel shadow in Tenacious Teal (another ELLE favorite is Sephora's Summer Cruise), then kept "the rest of the face soft and natural."

Gucci's latest eau, Bamboo, which was inspired by the idea of femininity balanced with power—and by the strong-as-steel resilience of its namesake—starts soft and grows in intensity, from a fruity opening to a spicy floral heart to a sandalwood dry-down. Fittingly, the brand enlisted Israeli actor Gal Gadot—Wonder Woman in the upcoming big-screen adaptation—as the face of the new scent.

For the past nine years, designer Jason Wu's runway love affair with vibrant, look-at-me shades of eye shadow—royal purple, molten gold, jungle green—has been a constant reminder that bright and bold makeup can look chic. "I'm a firm believer that beauty and fashion go hand in hand," says Wu, who packs his 12 favorite shadows (plus bronzer and blush) into Lancôme's Runway Right Away mega-palette.

Sally Hansen's revolutionary ManiMatch smartphone app takes the guesswork out of choosing polish: A simple scan of your hand allows you to try on more than 200 shades—including 14 new Miracle Gel colors launching in July—in real time. The app also provides expert shade recommendations based on an analysis of your skin tone—or, if a specific bottle catches your eye in-store, just scan the bar code for a 3-D preview, no drying time required.

When planning the lineup for his M.A.C lipstick collaboration, designer Giambattista Valli tested hundreds of hues on the women who work at his Paris atelier. "You need to go to people who wear it every day," he says. "I wanted something totally graphic, modern, contemporary. And that would suit girls from all over the world." The end result? Five saturated work-on-everyone shades, from a stunning pastel pink to a juicy black cherry.

Byredo founder Ben Gorham translates what he calls his most "personal" perfume, Flowerhead, into a portable roll-on. The oil base ensures the high-octane floral blend (inspired by Indian wedding ceremonies) will last longer than if spritzed, and the roller lets you reapply the scent of true love all day long.
