These blushes as far as I know are only available on the Tarte Website. I'm not sure why oit's not on Sephora, but maybe it'll pop up on there soon.
Here is what Tarte says:
A first of its kind! This creamy, long-wearing blush fuses the ease and blendability of a cream blush with the soft-focus and long-wear finish of a blush that has been airbrushed on the skin. The airsprun formula melts into skin, delivering a powerful dose of skinvigorating™ maracuja oil, and then dries down to a feather-light, long-wear flush with a subtle dewy finish. Awaken your complexion with a pop of maracuja-infused color on the cheeks and treat your skin to the repairing and hydrating properties of maracuja for a brighter and smoother complexion.
Both of these blushes have shimmer and tiny glitters to it. However, the shimmers aren't intense when you apply to the cheeks, they look nice! The texture of the blushes is much like Maybelline Dream Bouncy Blushes. They definitely have a bouncy feel to them. It's a cream-powder hybrid, kind of hard to explain unless you feel them yourself. The pigmentation is fabulous, not like the bouncy blushes at all. You can layer on for a brighter cheek, or use one layer for a soft pigmentation. I find fingers work best with this product, you can use a brush but I really feel fingers work better.
These definitely don't last as long as their amazonian clay blushes, so you might want to bring it with you during the day to touch up. After you apply it it feels satiny, not particularly dewy or matte. I really like them. $25 at Tarte.com
