Covers most of my dark spots and evens my skin tone. I got the 50N and 51W because I couldn't figure out which was a better tone for me. I mix them both but 50N is a good skin tone without having me look red-orange in the face. 51W works well too but 50N was a little better. I can use 51W as a foundation and act as if 50 N is a concealer for my eyes, chin, forehead, nose bridge, and eyebrow corrections. I would even just use the four ion and go about my day knowing it covers most of my facial skin imperfections. Smooth application with no smell. Only thing is I get itchy with a lot of things and also because I'm not much of an makeup person.
