What it is: A matte and luminously translucent SPF 15 powder in a dual-chambered, flow-through brush. What it does: This translucent, oil-absorbing powder lets you decide between three different finishes. Select "matte" to absorb shine, select "luminous" for a natural glow, or select "mix" to get the best of both! The velvety, silica-based powder blurs fine lines, while SPF 15 protects against harmful UV rays. The innovative flow-thru brush locks for no-mess touch-ups on the go. It can be worn alone or over foundation and is suitable for all skintones. What else you need to know: For a matte finish: Twist the barrel to "matte" to release the perfect amount of mattifying powder into the built-in brush. Target the powder in more oil-prone areas for added oil control. For a luminous finish: Twist the barrel to "luminous" to release the powder. Target the cheekbones, the bridge of nose, and the chin to give skin added radiance. For the best of both: Twist the barrel to "mix" and apply where desired. Size: 0.13 oz
