In Mac's website is described as "an aqua-spritz of vitamin and minerals, infused with a calm-the-skin blend of green tea, chamomile, cucumber, topped off with the fresh, natural, energizing scent of Sugi. Adds radiance, finishes makeup. Spray it on. Skin drinks it up!" This mineral infused spritz can be used as a medium for pigments, for your hair, for almost anything. It's so soothing, and refreshing, it is used to blend makeup (when it looks powdery/chalky) and make it look natural & healthy. I love it!
