i see no difference when i use it to highlight some bits on my face and it sucks as a concealer too.
that's because it's not meant to be a concealer. why would you use something that adds radiance to your face on a blemish? might as well take a highlighter to it.

I've never understood the hype either. Dior's version is a bit more moisturizing. A friend told me that Virgin Vie makes a really good equivalent of Karen Millen's solid highlighter.
