What kind of skin do I have? Oily, or dry?

I work in a warehouse, and when I apply bare minerals foundation in the morning, it looks good. In the evening when I go to wash my face, it is very oily, and it feels oily too. I wash my face with Enzyme Cleansing Gel from Mario Badescu, and just stopped using Cetaphil. I have bad acne, especially on my cheeks. When I wash my face, my face becomes dry, but not too dry. I peel on my cheeks, but I use a moisturizer. Help?
