Oily skin but also a lot of dead skin flakes. What skin type am I exactly and what should I use to make my skin healtier?

My T-zone & cheeks are very oily but after I shower (without using any products) it feels dry and there are a lot dead skin flakes all over my face. After a few minutes my skin will get oily again. I also have acne in my face, neck, chest and shoulders. My cheeks, chin, nose and the center of my forehead have some redness to them and have very visible pores. The pores are large/open but sometimes a thin layer traps dirt inside of my pores (e.g. nose). What skincare routine/products should I use?
