I really love this. It leaves a semi-matte and natural finish, and it works perfectly as a concealer. It has medium coverage that can be intensified, and the tone matches my skin perfectly. I have the lightest shade, and my skin is a MAC C15-20. No breakouts from it, lasts well on my oily skin, and the squeeze-tube container is SO much better than bottles. I don't use it all over my face, so I can't say if it leaves the skin flat-looking if used all over, but if you need a foundation to double as concealer and to just even out problem areas, try this on for size. I don't usually like Clinique, but this is a winner. No SPF, so you'll have to use a separate sunblock.
