Powder highlighters are makeup products in a powdered form that add a glowing shimmer to specific areas of the face, such as the cheekbones, nose, or brow bones, to emphasize and enhance those features. Full definition
I use powder highlighters in the summer because my skin tends to be more combination / oily, but in winter I like to use liquid highlighters and blushes because my skin is more normal to dry. (playdatesandpearls.com)
Then I sweep a coordinating golden powder highlighter on top. (allure.com)
I always have several highlighters on hand, but I'm currently loving Urban Decay's 8 Hour Powder Highlighter in Aura and NARS The Multiple in Copacabana. (bourbonlipstickandstilettos.com)
