Scarlett Johansson's Must Haves: From a Prada Purse to a Niacinamide Cream

After struggling with acne well into adulthood, Johansson has learned that building the perfect skin-care routine "doesn't have to be complicated" — but it is a worthwhile investment for your own health. She swears by The Outset Daily Essentials Regimen Bundle ($105), which encapsulates some of the brand's bestsellers within one seamless set.

"Consistency and good products can be the key to your healthiest skin ever," Johansson explains. "When I wake up in the morning, I'll wash my face using the Gentle Micellar Antioxidant Cleanser and follow up with the Vegan Collagen Prep Serum. Then, I'll use the Nourishing Squalane Daily Moisturizer and the Smoothing Vitamin C Eye + Expression Lines Cream, and I'm ready to go. Around the middle of the day, I sometimes even reapply the serum — my skin is addicted."
