Foundation Primers

Andrea

Just wondering if anyone can suggest a great primer to make foundation stay all day. Or any other tips? I feel like my foundation fades? after several hours even with a primer, liquid foundation, concealer, and setting powder. I just want to look flawless all day!! I also use Mac's Fix+ and Urban D All Nighter setting spray. I have noticed too that halfway through the day you can see foundation like in my pores. Not sure how to explain it. Primers I have tried include Make Up Forever, milk, dr. Brandt pores no more, Mac, becca.
