Some days a girl just needs a little complexion coverage, and some days she needs a whole lot more. Hey, we've all been there. Happily, this liquid foundation lets you go from sheer to full (and anywhere in between) with the squeeze of a dropper. Start with one to two drops, and gradually add more, depending on how much coverage you crave. (And for extra-smooth application, use the NYX Cosmetics Total Control Drop Foundation Brush, $14.) Bonus points for the impressive range of 24 shades.
You know when you buy a foundation and then realize the color isn't quite right? Maybe you've lost your summer tan, or maybe you're more bronze than usual. These drops are here to save the day (and save you a trip to the store to return said foundation). Available in either a lightening or darkening variety, they subtly transform the color of any complexion product: The former lightens and neutralizes yellowness, while the latter darkens and adds depth and warmth. We suggest having both on hand, just in case.
