I have sensitive skin, made dry by this terrible climate, so I've tried just about everything I can find. Here's what I've seen in drugstore/Walmart/Target....
I used CoverGirl's NatureLuxe for a while. Odd shades, but it was medium coverage and didn't break me out. I have really dry skin, though, and it was a very dry foundation. Their pressed and loose powders don't do anything for me. Even their lightest shade isn't light enough. Their Aqua line isn't bad. I'm trying it out here and there, but it has broken me out in the past.
You can find Elf at Target. Their HD Foundation and Powder is $6 each. Not terribly bad, but some people have said it breaks them out. Their primer also breaks me out. But REALLY REALLY cheap make-up! And I don't mean cheap is a bad thing. I have all their eyeshadow palettes, I've tried their lip products, and you can't beat $1 for some brushes, although I like the $3 line much better.
Neutrogena's Healthy Skin has a higher SPF, so it causes white casts in photos. Good coverage, smooth and easy to apply. But broke me and 90% of the make-up wearing population out, though.
Revlon's Colorstay Pressed Powder is AMAZING. I LOVE IT. If I didn't have dry skin, that is all I would wear. I'm trying out their liquid foundation now. The Photoready foundation has sparkly bits in it. Their AgeRewind sucks, stinks, and streaks.
Maybelline FitME is terrible. Streaky, light coverage. I liked their AgeRewind in the past because it was medium to full coverage, went on smooth, blended well, all good things.
Hard Candy's Glamoflauge (at Walmart) is the BEST concealer. It will cover anything and everything, and you only use a TINY dot to cover a large area. It is used to cover tattoos, so, go figure! Only issue is that is is very heavy, so you need a good powder to set and a good foundation to go under it. Otherwise, it gets oily and cakey easy.
I.D. Minerals aren't really that great for you. And personally, they made my face BURN. It looked like I had a sunburn for days afterwards. I couldn't even make it through the day, I had to wash it off. Apparently, that isn't uncommon. It's the only "high end" make up I've tried before.
