Of the three EDM base samples I tried in the free trial kit, this is the one I expected to like the least and actually ended up liking the most. However, I would not actually use it as a regular foundation, so did not mark that I would purchase it.
While the semi-matte formula moved/shifted on my skin on a balmy day and left me a bit shiny/sparkly, the matte formula stayed in place and even through a one hour cardio workout. Although that's the hottest/sweatiest I was able to put this to the test in March on a sample pouch, I was still impressed by its staying power.
The coverage is on the fuller side of medium, though it's not actually full and doesn't create a cakey, powdery or otherwise mask-like effect. It provides even coverage, blurring minor blemish remainder marks and neutralizing light redness. I still used liquid concealer for my dark circles. The shade 1W was a perfect match for my skin and the finely milled powder went on easily and blended nicely. It felt fairly light on, though not as weightless as the semi-matte.
The reason I would not commit to this on the regular is because it did feel somewhat drying on my combination/dry skin. I think that may generally be the case with many powders (and I'm used to using a liquid CC), even if the mineral formulations are purported to be the lightest. So I wouldn't say wearing it was completely "comfortable"; I was still aware that I had makeup on. I will give it credit though, in that in the short trial I used it, it caused no itching, irritation or skin problems. Also, you needed the least amount of powder of the three bases to get the "right" amount of coverage.
It's worth a try though - especially since you can try for free - if you're looking for medium, even coverage in an affordable mineral formula.
