What it is: A weightless powder that sets and prolongs the wear of concealer, camouflage and other undereye products for up to 12 hours.What it does: This no-flashback formula means you'll look great in photos, and it creates a soft-focus effect to instantly blur the look of fine lines and imperfections. The convenient compact allows for on-the-go touch-ups throughout the day. How to use: Using a powder brush, pat the powder over your makeup or onto your lids. Don't drag the brush over the skin. Because this powder contains white pigment, don't use it on your entire face. Keep it to areas that need to be brightened and lightened around your eyes. Dermatologist tested; ophthalmologist tested
