How to make foundation more creamy and less caky or fake looking?

I have combination skin, I'm oily in the T-zone area but my cheeks are super dry I also have redness and I have these weird little spots on my face kinda like hives.. There not red or anything is the same as my skin color...you could only really see it in bright light. My doctor said its nothing and that just how my skin is. Anyways anytime I put foundation on it looks good except for my cheeks...you could obviously tell I have make-up and it doesn't look good it looks kinda fake. Is there any way I can put on foundation without looking all caky? I've tried all kinds of foundation, I've used clinique, calvin Klein, sephoras collection, mac everything that's basically out. I've spent so much money and I still cant find something good for my skin. What are some tips to make my skin look nice and flawless? or is there anything you would recommend?
