MAC Mineralize Eyeshadow Quad features four coordinated colors of eyeshadow. Unlike most powders that are pressed into traditional metal pans, Mineralize Eyeshadow is moulded onto small round terracotta tiles and carefully baked for 24 hours, allowing for an exceptionally sheer and light application. Each eyeshadow features the brand's unique mineral-rich yeast extract, which blends 77 minerals that nourish while providing silky-smooth, buildable coverage. How to use: Apply it dry for low-to-medium coverage with a shimmery finish or wet for more intense coverage and color. When applying, use your fingertips, a brush or a sponge-tip applicator.
