African American with Large Pores and Oily Skin

I am an African American with very oily skin and very large pores. I have been using Tazorac cream and Clindagel for over 2 years now. During the first courses of these prescriptions, my face cleared and reacted fine, but now my face is extremely oily, looks scaly, thin, and seems to have a constant shine or gloss, and my pores seem to have gotten larger.

What do I need to do in order to minimize the appearance of my pores and control my skin's oiliness? I know Tazorac is drying but for me it makes me more oily. I feel Accutane is my next best option but it's relatively expensive.
