Jay Sean's Must-Have Products: From the Nintendo Switch to His Favorite T-Shirt

Sean had a pretty basic skin-care routine consisting of just a moisturizer until his daughter told him to level up. Now, he loves using Kiehl's Since 1851 Ferulic Brew Facial Treatment Essence ($62), which helps hydrate his skin and keep his oily t-zone balanced. "As soon as you put it on, you just feel vibrant instantly, [achieving] that kind of dewy skin which looks healthy," he says. The facial essence is an antioxidant-rich formula with ferulic acid, lactic acid, and squalane, which helps to brighten and smooth the skin. He follows it up with a moisturizer and SPF in the morning, and at night, he uses a vitamin C serum.
