YSL Grey Splash (01) Full Metal Shadow ($30.00 for 0.15 fl. oz.) is a medium-dark gray with a metallic sheen. It was sheer with a thin, watery consistency that made it difficult to layer or apply evenly. The only way it worked decently (well, that's probably a stretch) was to apply a thin layer with my fingertip and keep it as a sheer wash of color. One out of four pulls seemed to grab enough of the actual color product to apply semi-opaque coverage (that's the lucky one you see as it is applied on my lid), and from there, it started to flake away after six and a half hours. Literal chunks of silver-gray pulling away from the skin and leaving gaping holes behind. See comparison swatches / compare dupes side-by-side.
Yves Saint Laurent Full Metal Shadow is the brand's first metallic-color liquid eyeshadow. Its pigment-packed formula lasts up to 16 hours without creasing, flaking or fading and contains 40% water for a cooling effect and pure color payoff. An exclusive applicator allows you to create three signature looks, including a full lid, just the line or a graphic eye.
