Venus Williams's Must Haves: From Beam's Sleep Powder to a Pair of Lacoste Sneakers

Williams agrees that sunscreen is vital to any morning routine and loves using this EleVen Ace the Day Face Lotion SPF 30 ($38), in particular. "If you incorporate SPF into your routine, then you're actually defeating the sun — it's not defeating you," she says. "We're getting sun at all times; we're getting sun when we're driving in our car to work. And that sun takes a toll."

Pro Tip: Williams says this formula is a staple in her antiaging routine, but even better, it's also designed for layering, so you can "make it your own." "I like it if you can layer your sunscreen and put makeup on top. Your sunscreen should work with everything that you're doing," she says.
