What it is: Water-activated eye shadow palettes in colors that transform into a radiant, intense, metallic finish. What it does: These eye shadows can be used dry, like a traditional eye shadow, for a subtle shimmering effect, or wet, for a full-intensity pigment metallic finish. These remarkable properties give everyone the freedom to create any kind of eye look from simple to dramatic in seconds. What else you need to know: Yves Saint Laurent labs have invented the "water process" Pure Chromatics eye shadow. This process uses water, in place of a solvent, to develop the formula. Once pigments are mixed with water, dry, pure-pigmented powders are left with a very high level of shimmer.
