Formulated with 100% non-nano zinc oxide, brightening viniferine and smoothing niacinamide, this Spf 50 daily mineral sunscreen visibly reduces the look of dark spots and evens skin tone. Its non-greasy formula has a lightweight texture that leaves a glow finish and works well as a makeup base. When using a mineral filter, like zinc oxide, to reach a high Spf 50 coverage, a white cast can occur. This is due to the weight and thickness of the filter for sun protection. For best use, shake well, warm the texture and work the product into your skin.
