A skin-perfecting duo that helps custom-correct dark circles, spots, redness, dullness and more. What it does: Each duo has two levels of coverage. On one end, a light, luminous, wears-all-day formula with brush applicator to sweep across larger areas. On the other, a full-coverage hydrating concentrate with a sponge tip to cover targeted areas for up to 24 hours. It helps blur the look of imperfections for a flawless, even skin tone and creates a flawless base for your concealer and or/foundation. How to use: For best results, apply before your concealer and/or foundation. Gently tap on with the applicator and lightly blend with your fingertip or a brush.
