The Miracle Skin Transformer is a very different product from the Cover FX CC Cream. The Miracle Skin Transformer has more of a slick texture, where the CC Cream feels more like a liquid foundation. Furthermore, it offers more light-medium coverage, whereas the CC Cream is thicker in texture and offers medium-full coverage. They're both excellent products, but if you like a slick, light-weight product that offers lighter coverage, you might want to stick with the Miracle Skin Transformer. If you ever want to bump up the coverage without transitioning to a foundation, though, the Cover FX CC Cream would be a terrific product for you to try!
Love the Cover FX, it has a lot more shades and benefits! Go for it!
