Highlighter sticks are used to highlight, brighten, and illuminate your features. We love using Wonder Pencil for precise detailing and micro-highlighting on smaller areas, like the brow bone, inner corners of your eyes, and your waterline. You can also use Wonder Pencil to outline your lips to fake a plumper pout. If you try this at home (or on the go), make sure to use the matte, rather than shimmer shade, for the best results.
