As if you needed any more reason to love Pauline Chalamet, turns out she will also be appearing in one of the most anticipated movies of the year: “The Devil Wears Prada 2.” While her “Sex Lives of College Girls” days might be over, the actor has translated that effortless cool-girl style to her latest project, and it was most evident when she stepped out onto the carpet at the premiere in New York City on April 20.

Her lit-from-within glow was courtesy of makeup artist Lisa Aharon and legendary French beauty brand, Lancôme. Aharon was kind enough to share all the behind-the-scenes details with Popsugar — from the skin prep she used to create the perfect base for makeup to the exact eyeshadow and blush she dug into for this look.

“[Chalamet’s] black Honor NYC silky dress with subtle black floral detailing felt sleek but still romantic, so the makeup followed that lead,” Aharon says. “We kept her skin fresh and light and let the eye pick up a bit of that darker edge from the gown.”

First, the inspiration for the night:

For starters, Aharon says that flawless makeup application starts with the right base. To keep Chalamet’s skin hydrated and smooth, she used Lancôme’s Absolue Longevity MD Anticipate The Cream ($155). She then went in with the brand’s La Base Pro Face and Makeup Primer ($45). But the real secret to her all-over glow? The brand’s Nutrix Royal Body Butter ($54), which she used on her arms, chest, and décolletage to add radiance to the skin.

“One detail people might not notice [is] the subtle dimension in her skin,” Aharon says. “Nothing heavy, just soft shaping and glow in the right places. It makes such a difference without ever looking obvious.”

Finally, on the lips, the exact rosy-mauve shade of L’Absolu Rouge Intimatte Lipstick ($35) that Aharon used was 340 Love Whispers. The final secret, though? Lip Idôle Butterglow ($32) in Pink Ôh La La was also used to make the wear more comfortable, blurred, and modern. It also tied the whole look together without looking overdone.
