For spring 2012, I'm drawn to Roses quint, the pinks and purples are so feminine. I also like the nail polishes, the green reminds me of Jade Rose!

The Rosy Glow blush is pretty in the pan, but I'm quite skeptical. It sounds gimmicky, and I tried on their Rosy Glow lip balm they had earlier on, and to my disappointment it remained colourless on my lips. At least for a balm if it is colourless it still gives moisture, but if a blush gives no colour what use is it, lol.
I have to admit that I'm drawn to the blush and the Roses quint, but I'll have to see them first. I was intrigued by the description: "Rosy Glow works in the same way as those gel blushers that turn a different shade on everyone and rely on the heat of the skin to change colour".
Sounds like an interesting new formulation -
