Yes. You can't rely on makeup alone. "To get adequate sun protection, you have to apply an even coat all over your face," says Dr. Cassis. "If you just put on foundation wherever you need coverage, you won't get an even layer." Plus, makeup sits on skin's top layer and wears off quickly, whereas a moisturizer's chemical sunscreen is absorbed by skin, making it more effective. Use a moisturizer with SPF 30, such as First Aid Beauty 5 in 1 Face Cream ($38, Sephora), 365 days a year.
