Hourglass Iridescent Light is a neutral-toned, light peach with a luminous finish. It is a limited edition powder that retails for $48.00 and contains 0.35 oz.
Iridescent Light is a "sheer illuminating highlighter." It is a very light, peach-hued beige with white shimmer. The texture is soft but dusty (more so than most Ambient Lighting products) and produces a light sheen. I imagine it will be appealing to anyone who finds the average highlighter too much. I'm not sure if this will work as well over deeper skin tones, as it has a whiter base against my skin tone, but it may work and it may also work if layered over a blush. It wore well for eight hours on me. MAC Mystery Princess (LE, $22.00) is more shimmery (90% similar). Urban Decay Luminous (P, $30.00) is more shimmery (90% similar). Cle de Peau Pastel (11) (P, $55.00) is more shimmery, lighter (95% similar). Kevyn Aucoin Candlelight (P, $44.00) is more shimmery, lighter (90% similar).
