Buttercup is Amazon's choice for setting powder. It is completely flash-friendly and available in two shades; BUTTERCUP LIGHT is recommended for light to medium skin tones and Buttercup for medium to dark skin tones. It can be used to highlight, set/bake your concealer or can be used as an all-over face powder. They do not give off a white cast or turn ashy in bright lighting or photos. They absorb oil, reduce shine and keep your face matte for hours.
