What is the best drugstore make up and the best department store makeup? Foundation?

I have skin like you. Oily skin can make some products look blotchy at the end of the day. So what I use as a base is....Well, it looks like a lot of brand names, so I would just look up Farle Couture, & it's a very good one. It also has SPF 20 in it, so it will protect you from the sun. Don't use a bunch since it's sort of on the expensive side. You don't need that much, anyways. & then put on some mineral powder on top. I use Mabelline New York Mineral Powder. It has micro minerals in it & the powder's pressed. You just use a little pad & rub it on your face. The base I used for that stuff though before, made me look very fake & robotish. So, Farle Couture is very good & doesn't blotch! :)
