YSL Eau d'Argent (02) is a slightly cool-toned, very light white with a metallic finish. It is a permanent eyeshadow that retails for $30.00 and contains 0.15 oz.
YSL Eau d'Argent (02) Full Metal Shadow ($30.00 for 0.15 fl. oz.) is a brightened white with sparkle and finer silvery-white shimmer. It is sheer, watery, and thin. It flakes off easily, wears poorly, and is incredibly challenging to build-up. I would apply a layer, let it sit, wait for it to dry... wait a little longer, just to be safe, and try applying another layer, but to even out the layers, it ends up causing the underlying dried layer to flake away. It had already half-flaked off after a mere two hours of wear. 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.
