This all-natural multitasker is the true definition of a skin-care-makeup hybrid. The formula combines brightening vitamin C and licorice extract with a trio of acids (glycolic, lactic, and azaleic) to knock out dark spots and dullness, while squalene and hyaluronic acid pack a hit of hydration. So, yes, you could use this as your daily skin-care serum, but it also pulls double duty as a primer and/or highlighter, delivering the perfect amount of natural-looking luminosity. One makeup artist explained it as "the all-natural version of Becca Cosmetics' Backlight Primer."
