Obagi Sun Shield Tint Cool provides complete sun protection from UVA, UVB, and infrared rays. This sunscreen is tinted to match your natural undertone rather than skin tone, which is a system that helps to enhance your natural complexion. If you have a more blue, red, or pink undertone, fair skin that burns more easily, or forearm veins that appear more blue in color, this cool shade is ideal for you. This product has an active IR technology that prevents heat-derived oxidative stress, and other key ingredients help provide the broad spectrum protection. This product is hypoallergenic, dermatologist-tested, and fragrance-free.
