"I have tested many beauty products in my time as an editor, but the Rare Beauty Positive Light Liquid Luminiser ($22) feels so easy to use and doesn't budge throughout the day. As for the product itself, it doesn't feel super sticky like some other liquid highlighters do. Sometimes, wearing highlighter just feels like I have a layer of goop on my face, but I forget this one is on until I look in the mirror at the end of the day. You don't have to apply much product to your cheekbones to get a nice shimmer; I just tap on a few dots along my cheek with the applicator, then blend it in with my fingers." — NC
