Obagi Sun Shield Tint Warm 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 yellow, golden, or olive undertone, a darker complexion that tans easily, or forearm veins that appear more green in color, this warm 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.
