WHEN: The Golden Globe Awards, Jan. 13

WHY IT MATTERS: An unexpected beauty move delivered the best look of the night and made coral-orange lips the “it” color.

MUST-HAVE PRODUCT: Hourglass Opaque Rouge Liquid Lipstick

The inspiration for Alba’s bold lip was her strapless melon-hued Oscar de la Renta mermaid gown. Much like the dress, the makeup needed to be “classic with a touch of something unexpected,” says Avon Global Celebrity makeup artist Lauren Andersen.

For a “warm and glowy” complexion, Andersen used tinted moisturizer, a light dusting of rose pink Hourglass blush and a soft neutral eye palette of espresso liner and sand shadow. “With the rest of the face soft and pretty, her lips were ready to take on all of the focus,” says Andersen, who painted Alba’s pout vibrant orange with Hourglass Opaque Rouge Liquid Lipstick in Riviera, a long-wearing matte lipstick.

Her Globes moment ignited the year’s citrus-hued lipstick frenzy on the red carpet (worn by Drew Barrymore, Selena Gomez and Bella Thorne) and on the spring 2014 runways (spotted at Prabal Gurung, Rag & Bone, DKNY). Says Andersen: “It’s fun to be experimental with beauty, and a bold lip is an easy way to play.” Speaking of playing, Alba and Andersen have known each other since their early teens, when they staged photo shoots from Caboodles kits full of makeup. Says Alba, 32, “We would go to the mall [where] every color eye shadow was glittery. It was like a budget version of A Midsummer Night’s Dream. Glitter everywhere! [Working with Andersen] feels like that, just fun.”
