For the price point, this product really sucked. Guys not even less than 3hrs of use the compact broke into tiny pieces and I had to cover it with the sponge that comes along with the compact to prevent from further breakage. The coverage is good, it blends well into the skin and has a natural finish, but the actual value for money is NOT THERE. If you want to pay this much for a foundation compact that is also good for your skin then just go for the Westman Atelier Pressed Skincare Powder.

Not my favorite.

Color: Medium Sand

I wanted to like this foundation, but it ended up being too drying on my skin. The finish looks chalky rather than smooth, which makes it hard to get a natural look. Unfortunately, it just didn’t work well for mE.
