I've had this foundation for over a year and at first, I used it every day. Now, it just sits in my foundation drawer in my organizer. I bought it initially because I really wanted to try a new powder foundation due to the fact that, in the summer, my skin gets extremely oily, and liquid and cream foundations exacerbate the oil and end up causing breakouts. Well, this did help with oil, I'll give it that. However, it severely clogs my pores to an extent where it's extremely noticeable and the texture of my skin becomes rough to the touch because the debris in my pores is raised. No amount of exfoliation, masks, pore strips, or even a Luna Mini was able to clear them out. I had to stop using it completely, and then it took months for my skin to become smooth again, with a lot of effort and products.
As far as the foundation aspect goes, I thought it was decent, but was never blown away by it. I bought the shade Light, which is actually too tan looking for my neutral undertones that do lean more toward yellow (as opposed to pink). The coverage itself is so-so. It does a good job of evening things out, but, if you're someone that suffers from acne, rosacea, or acne scars...this is not going you do it for you. If you have mature skin, this is going to accentuate any lines, creases, and dryness.
I also found that it leaned toward cakey way too easily. It really makes pores more noticeable (most likely bc the pores are just pulling all of it in for some reason), and can look quite powdery.
For an "Illuminating" product, I found that it did very little in the illuminating dept. It does have a very slight (and I do mean slight) pearl shimmer to it when swatching on the hand, but it doesn't render as anything when applied to the face.
The powder itself is surprisingly chalky as well. I'm surprised when I come across a product that should be finely milled when it's not, like a powder foundation. For a higher end brand, the formulation is very cheap feeling, IMO. The price certainly does not reflect the quality.
I wouldn't recommend this in any capacity. There are much better powder foundations out there.
