Herr prepped the 51-year-old actress' skin with a hydrating sheet mask and layered on a rich brightening cream to lock in moisture.

Next, Herr based Roberts' face with hydrating primer and a long-lasting liquid foundation to give her a nice, even skin tone. The MVP product of Roberts' look was the $25 Lancome Le Monochromatique cream-to-powder tint, which gave her cheeks a bright rose-colored flush.

Her eyes were lined and winged out with black eyeliner. They were also played up with a high-low mix of metallic and muted eyeshadows and volumizing mascara.

Herr finished the look by lining the lips with a raspberry-toned lip liner, and a new neutral lipstick slated to launch this spring, called Lancôme Le Mademoiselle Shine in 232 Mademoiselle Plays.

Roberts is a spokesperson for Lancome, and all of the makeup she wore for Oscar's night was from the brand. Her finished face was mesmerizing and we couldn't get enough of it.

Glow on Miss Roberts!
