MAC Mineralize Eyeshadow Duos are my absolute favorite eye shadows, and Polar Opposite is a great example of why these shadows are so fabulous. On one side is a shiny silver shadow, perfect for layering with a dark eyeliner (I recommend MAC Fluidliner) for a night out on the town. The other side is a mosaic of different colors...browns and silvers. When swirled together, it produces a shiny taupe color that is very complimentary to any eye color. Worn with an earthy eyeliner, it would be low key enough for daytime wear and professional enough to wear to the office. The MIneralize Eyeshadows are perfect for anyone who wants a shimmery eyeshadow that is versatile enough to blend for any occasion. And because MAC created these using minerals, they are easy on the eyes and don't cause irritation. The shadows also don't use chemicals that might irritate the skin. They also last all day long without creasing or fading. I recommend all MAC Mineralize eye shadows, and this shade in particular.
