The holiday weekend is right around the corner, which means it’s time to think about your heat-proof makeup essentials. We all were just as curious about what to pack in our makeup bag, so Lancôme rang celebrity makeup artist Sandy Linter—also Lancôme’s Beauty At Every Age Expert—for her makeup must-haves.

Here’s the scoop: “The new Ageless Minérale Blush delivers the thinnest, sheerest amount of color to the skin. It’s a powder, so it looks great in the summer but it’s soft and sheer enough for all ages.”

“Teint Idole Fresh Wear Foundation evens out the skin tone and then disappears, like you’re not wearing a foundation. Makeup should look effortless, especially in the casual summer months. Fresh Wear is perfect for this effortless look. It also happens to feel great on the skin.”

“Wearing sunglasses can heat up the skin around the eye area. This can smudge eye makeup, but not when you’re wearing waterproof mascara. My go-to has always been Définicils Waterproof.”
