However first determine the cause and then definitive recommendations can be made. Start with your internist or dermatologist.

Not a short answer: Where is the skin oily? This is typically a facial problem. Seek consultation with a dermatologist (or facial plastic surgeon if appropriate). Depending on the details of your condition, there are different treatment options. Rough skin can be helped by an appropriate moisturizer. A retinol type product can help with oily skin.
