Desperately need help!

I have severe dry skin and cystic acne, I need to find a good drug store moisturizer and drug store foundation! Do any of you ladies have any suggestions?! I've tried maybelline fit me, and revolon color stay and neither of them work. They make my skin look cakey and try. I can't afford the expensive makeup from ulta or sephora so I need only drug store brands. Thank you!!!
