Pat McGrath Interstellar is a very cool-toned, medium-dark purple with a sparkle finish. It is a limited edition eyeshadow that retails for $25.00 and contains 0.04 oz.
Interstellar is a medium-dark, bluish-purple with cool undertones and a sparkling finish. The texture was denser and a bit stiffer compared to other shades in the palette with a firmer press. It had nearly opaque pigmentation that applied evenly to bare skin when I patted and pressed it on using a flat, synthetic brush. It blended out nicely along the edges, but some of the sparkles pulled away from the base color a bit too easily so it was harder to avoid getting sparkle a bit beyond where I had initially intended. It wore well for nine and a half hours with slight fallout over time.

The creamy, soft shadows ignite metallic, pearlized pigments and amplify color. Experience an emollient-like texture and sensorial feel that glides on with one-stroke, fully-pigmented, opaque color saturation and a polished, bright, multidimensional finish.
