Hourglass Cosmetics Ambient Strobe Lighting Powder is an illuminating strobing powder designed to sculpt the face with light creating depth and dimension for a refined, natural highlight. Ambient Strobe Lighting Powders are formulated in a sheer base with concentrated ultra-fine micro pearl particles in varying sizes and refraction levels to give off a naturally luminescent highlight to the skin without a heavy metallic finish. Developed with Photoluminescent Technology to capture, diffuse and soften surrounding light to refine the appearance of the skin. Can be used wet or dry for varying levels of intensity, taking you from day to night - from an everyday, wearable strobe highlight to a dramatic evening strobe highlight.
