Finding the right shade of foundation can be tricky to begin with, but even when you find one you like, it may not always work for every occasion, season or look you’re going for. Some days, for example, you might want a warmer undertone to your makeup, while others call for something cooler. Or, you may want your foundation to pull double duty and serve as a contouring or highlighting product and wish it was just a tad lighter or darker. And then there are those times — vacation, summer, too much self tanner — when your skin tone changes and renders your foundation essentially useless. These instances (and so many more) are exactly why NYX Professional Makeup came out with the new Total Control Pro Drop Foundation and the Total Control Pro Drop Foundation Hue Shifters. Ahead, we tapped NYX pro artist Autumn White for tips and tricks on how to customize your foundation shade in just a few drops.
