Pat McGrath's eyeshadows are, generally, supposed to be "super-saturated" with "creamy, soft textures" and "extreme blendability and adherence without creasing." A lot of how well they perform (and to some degree, how they are supposed to be applied and marketed) depends on the type of shades, but by and large, the eyeshadows perform very much as they are described.
The mattes are velvety, blendable, and dense without being thick or too heavy, and they have semi-opaque to opaque pigmentation where a little can go a long way with some of the deeper and richer hues. The satin and pearl finishes are smooth, lightly creamy, and firmer but not dense or thick with good pigmentation, blendability, and easy application. The more metallic finishes tend to be softer, creamy, and smooth with a bit more denseness and no powderiness. The sparkly/glittery shades are often designed to be applied wet for richer coverage or intensity, which has largely been my experience. Most of the shades last between eight and nine hours.
