I've actually had this foundation for months now. I purchased it around Christmas time, and have only used it 3-4 times. The product basically is what it says. It is very lightweight (can't feel it on), creamy, has a light coverage with a semi-matte to matte finish.
This foundation is probably the sheerest foundation I own. It is slightly buildable from sheer to a light-medium. It will not build to a true medium. Once it's built, it doesn't look thick or heavy. The redness from my cheeks as well as blemishes peek through. I find that this foundation oxidizes slightly (Gets darker), a couple of minutes after applied. When I'm tan, it's a great color match. When I'm not tan (currently), it makes me look a bit orange. The finish of this foundation is matte. If you have oily skin, or apply a moisturizer prior, you may have a semi-matte finish. I don't find this foundation to be long lasting, as it starts to fade almost right away. I don't really care for matte foundations, with the exception that they have great coverage (EL Double Wear for instance). This foundation is sheer AND matte.. making my skin look dull, with imperfections not covered. Each time I wore this foundation, I tried to like it.. but I just don't. It's not for me.
If you have pretty good skin and are looking for a foundation with light coverage that will even out your skintone and you prefer a matte finish, you may like this foundation. Or if you have oily skin and need little coverage. I do not recommend this for dry skin or for those who are looking for a good amount of coverage.
