Prescriptives makeup is like no other brand on the market, because it is one of the first companies to make custom cosmetics available to the public. They use a system called Colorprint in order to create cosmetics that match your skin to a tee. How the Colorprint system works is when you visit one of their stores, one of their custom blend analysts will test your skin using four neutral shades which will determine what your skins undertone is. Everyone falls into one of four categories: yellow/orange, red/orange, red or blue/red. Once this is determined, the analyst will hand blend a foundation for you, or you can order your cosmetics online.
