I am fascinated by Inglot's AMC lip glosses! (AMC = Advanced Makeup Components) They impart glowing iridescent rainbow washes to the lips. They're not distinctly glittery with holographic sparkles, i.e. calcium aluminum borosilicate. Rather, they look like smoothly multichrome oil slicks. In swatches, it's difficult to capture their beauty completely.
