Guerlain Star Dust (900) Maxi Shine Lip Gloss ($36.00 for 0.12 oz.) is described as an “iridescent ray of pure light.” It’s a virtually clear gloss with multi-colored, iridescent shimmer that flashes aqua, green, blue, and pink. It’s slightly milky, so it mutes the natural lip color just slightly, and it has a fair amount of shimmer. MAC Oh My Darling (LE, $15.00) is similar when applied but not as iridescent. Giorgio Armani #700 (P, $29.00) is similar but slightly warmer in tone. MAC Impossibly Sweet (LE, $15.00) is pinker. See comparison swatches.
