HOURGLASS INNOVATION: Hourglass developed this formula to prime skin and create the perfect canvas for the Ambient Lighting Collection. The first-of-its-kind formula was developed to create the thinnest layer of light-enhancing particles, which allows for layering without re-emulsifying the layer underneath. This results in the most weightless lighting effect on the skin. This breakthrough primer creates the ideal base for light diffusion and refraction while also prepping the skin for makeup application. CARISA\'S TAKE: “This primer is a multi-tasker. I wear it alone on days where I just need a little something to walk out the door, and under foundation on other days when I want to really perfect my lighting. The texture is so different than anything else on the market - it feels like I have nothing on, but it does so much.”
