Never used. This tinted, broad-spectrum, oil-free sunscreen protects the skin against harmful UV rays and visible light. The universal tint, derived from iron oxides, not only provides a natural-looking glow but also serves as an extra defense against dark spots. Formulated with thinly sliced micronized zinc for smooth application and thorough coverage, we've also enhanced the formula with caffeine to help shield skin cells from UV radiation damage and slow down sun damage that leads to wrinkle formation. Additionally, lactic and hyaluronic acids work together to brighten and hydrate dull skin, completing the ultimate skincare regimen.
