When I first started using makeup, I simply could not understand the concept of loose setting powders. They're messy and offer no coverage? What's the point, right? As I later discovered, there's a whole lotta point. First of all, loose setting powders, the good ones, are usually extremely finely milled. Much more so than a pressed powder. If need ever be, you can layer this and layer this and never look cakey. They disappear completely into the skin. Plus, if your foundation already gave you all the coverage you needed then there's no need to add more. Less is more, after all.
The Laura Mercier Loose Setting Powder possesses all those qualities: finely milled, non-cakey, and it controls oil and shine. I also found in it a quality that not all setting powders have and that is its texture. It's so soft, that it makes your face feel and look smoother. On my skin I only need to use very little product to get the desired effect. And although it's pricey, the pot will last you for ages. Before purchasing the full size I was using a mini pot which is half the size of this one. And that lasted me for over a year. Some HD setting powders are infamous for causing a white cast in flash photography. However, I've never experienced this with Translucent. I believe the culprit is a high amount of Silica (just like high SPF can cause flashback in foundations) which the Loose Setting Powder does not contain.
A lot of people love this. As of now, it has a rating of 4.6/5 on Sephora.com. I highly recommend it and it has been my favorite setting powder for years.
