EnkoreMakeup beautifully explains how to change the color of your foundation using color adjusters from Coastal Scents. I was so inspired by the clip that I purchased a set of adjusters to keep in my kit.Does your foundation look too pink or yellow on your skin? Don't settle for a lousy match. In some cases you can return your foundation and get a better match. But if the company doesn't make a perfect match, your only option is to alter it using color adjusters.
