NARS LIQUID ILLUMINATOR IN SHADE - COPACABANA NARS illuminator in Copacabana is a very nice pearly liquid highlighter. It is incredibly versatile, as you can use it on your face pre-foundation as an illuminating primer, mix it with your favorite foundation for a more glowy finish or then use it as a glowy highlight on top of your foundation. I find that it mixes well with all sorts of different foundations without separating or such. Also when used as a liquid highlighter, I never have to worry about it disturbing the foundation underneath. Despite the mostly natural sheeny finish, it is a very pigmented product. You really need half or maybe even 1/3 of a pea to get a beautiful glow!
