I purchased this CC cream in both tones; light and medium. The light is good for my skin in the wintertime. I usually use light beige in the Too Faced Born this Way foundation (to give you an idea of the colour). The medium is great for when I get tan in the summertime.
This is a good quality moisturizer. I can't yet speak to the effects for colour correction, as I haven't yet used it long enough to get results.
However, the coverage is GREAT for a CC cream. It certainly gives more colour than others, as I find usually CC creams are extremely sheer. This one is not. I find the coverage is closer to a tinted moisturizer.
The smell is offputting, though, that's like the only thing I dislike about it. It does come out fast, so be careful when opening the tube. A little goes a long way...if you apply too much, it's difficult to blend it all in. I still use a concealer under my eyes when I use this CC cream.
