According to bareMinerals, it "diffuses the look of imperfections while reducing shine for a flawless finish throughout the day. Powered by our proprietary SeaNutritive Mineral Complex, this formula delivers incredible skin-nourishing benefits." It is a basic, high quality translucent powder that I use to set my makeup everyday. It does not leave any color behind. A light dusting extends the wear of my foundation or tinted moisturizer without looking cakey or feeling heavy. It will have a slightly powdery look for about half an hour until it settles onto my skin. A light mist of water will also help it to settle quicker, especially for those with dry skin. Also, dusting or "pressing" on a second layer with the included sponge for the evening does not seem to leave any build up. It just absorbs oil and looks refreshed.
