Light to Medium Colour

I purchased this product in the light to medium shade. I'm very fair, and always the lightest colour in all foundations. This product is much too dark for fair/light skin. What I do is mix this in with my foundation, which creates a better skin match. I did wear this one day on its own and I didn't find that it was an effective moisturizer. I do have to apply my own moisturizer (lightly) before priming and putting this one on top. The overall reason why I purchased this product is because all foundation/concealers clog my pores by the end of the day, and I wanted to find something to put under my makeup to prevent that. I did notice with repeated use that less and less clogged pores showed up. Overall, I think this is an average product. It is about 70% effective, is really sheer coverage, and way too dark for me. Unfortunately I won't purchase again unless they come out with a lighter shade.
