Magic on your brush
PROS: Let me start off by saying that my absolute favorite MAC blush is Coppertone, it has a rosy/gold tone to it that is absolutely stunning. I can use this color in winter and in summer, I think it could go with any skin tone. It is very natural and not too blunt. Now, all MAC products have really awesome pigmentation, so you'll never be let down. You don't have to use much of the product to get the full-effect of the color, which allows you to use the product for a long time. And MAC has a rediculous amount of color choices, so you can go for a bolder look with a brighter blush, or you can stay natural with a neutural color.
CONS: If you over apply this product, your skin can end up looking oily, due to the shimmer in the blush so you have to be sparing with it. It is also pricey, not drug store affordable, but I think it's worth the cost. You get a lot for your money.
Likewise this is also my to-go blush. I wear Coppertone to brighten a cheek in a light way. The color is gorgeous and the blush is high quality. This blush blends well and lasts. Overall, I think there are better blushes, but this is such a classic.
