I am constantly trying new foundations, both drugstore and high end, looking for my holy grail. I am nearing 50, have dry skin, and some large pores on my cheeks. My job can be hot in the summer, so I often sweat. I put foundations through it. This foundation is awesome, and beats most all the higher end foundations I've tried. I also love the Cover Girl Healthy Elixer, and often mix the two and get the perfect finish. You won't go wrong with either one.
Very light coverage, although the colour is a bit light for my skin tone.
I also ordered 520 light and it suits better. But if you have pale skin then go for the 510 fair.
