Aside from the cute packaging, the two face/complexion Y-Mail palettes in the Yves Saint Laurent Spring 2010 collection are very low-key. The face highlighter didn't entice me at all in its pink glory, and the blush is nothing we haven't seen before, except that it's actually very pretty and has a luxurious low-shimmer and very silky finish. The palette is made of three colors and with a little practice you can control how much your brush collects from each one of them.
The colors are on the lighter side and my complexion in all its winter pallor is probably the darkest one that can wear them (I suspect this holds true for the entire YSL spring collection). If I were tan the Y-Mail blush probably would have been impossible to detect on my face. I tested several brushes and found that such a light blush- both in color and in texture- benefits from using as dense a brush as you can find, be it angled or even a kabuki-style. A fanned brush is utterly useless here. The silky finish is pretty and the very low shimmer makes it office friendly and very natural looking.
Bottom line: Nice but too pricey for what it is.
YSL Y-Mail Palette Blush Harmony Silky Finish ($65) is available from most decent department stores and online. I bought it directly from the company's website.
