While temperatures have been skyrocketing on the East Coast this summer, Martha Stewart isn’t sweating it.
The 84-year-old beauty mogul raved about Lancôme Teint Idole Ultra Wear Foundation on Instagram today, saying the long-lasting, waterproof formula “can take the heat.”
“It’s a really good thing,” she added in the sponsored video, which sees her wearing the base for everything from baking to a glamorous cocktail party.

The “undetectable and unforgettable” formula is a longtime Hollywood favorite, designed to last up to 24 hours (!) while remaining breathable and hydrating. (Kathy Hilton and Kris Jenner have also both raved about it in videos with the brand, with the latter saying it “goes on so easily” and “feels like silk.”)
Stewart’s also become a fan of Lancôme’s newest launch, the “surprisingly weightless” Teint Idole Shape Stick.

Before teaming up with the brand on her latest video, the domestic doyenne told InStyle she uses it anywhere she wants a “little extra coverage,” in addition to applying a darker shade along her cheekbones and jawline for “subtle definition.”
“I use it to quickly perfect my complexion without any fuss,” she added. “Everything blends beautifully, so the result looks polished and natural.”

Depending on which shade you choose, it can function as highlighter, blush, contour or foundation — all in one swipe. (Stewart’s not alone in her love for the launch, as Angela Bassett recently posted her own video with the brand.)
While Lancôme has plenty of celebrity favorites in its line-up (more on that below), the new stick is one to watch. After all, when Stewart declares a new “really good thing,” we’re immediately taking note.
