Before I begin commenting on this gorgeous powder, I want to add that I use this ONLY on my undereyes to set my concealer. This powder is the MOST REFLECTIVE SETTING POWDER I'VE EVER SEEN/SWATCHED!! It's INSANE how much light it reflects. And it lasts for HOURS. I was using the 'Laura Mercier Secret Under Eye Brightening Powder' and it caked up my concealer (I use UD Naked). So I wanted a real brightening powder solely for my undereye, because my dark circles are so deep mauve. This was fantastic in brightening them, and it didn't cake up my concealer (not to mention it didn't cause creasing)! However I DON'T RECOMMEND this product if you are going to take ANY flash photos during the day/night.
