Jenna Dewan's Must Haves: From a $6 Cream to a Luxury Mattress

In the morning, Dewan starts her day with two key beverages: hot water with lemon, followed by coffee. Then she goes into her skin-care routine — it's something she takes very seriously. After a bad experience with a laser treatment left her with melasma on her face, she swears by vitamin C serums to fight hyperpigmentation. "I'm obsessed with the Neostrata 15% Vitamin C and PHA Serum ($55)," she says. "It's really changed my skin a lot."

Pro tip: If you have melasma or hyperpigmentation on your face of any kind from acne or the sun, consistent use of vitamin C can help fade the discoloration. But that's not all: it's imperative you protect your skin from the sun, as it can worsen these conditions, by using an SPF of 30 or higher every day.
