How do I get rid of this?

In september of last year I decided to buy neutrogena water gel because I got told told that my skin was too 'oily'. Before my skin was completely fine and I was using cerave moisturising cream and la roche posay sunscreen 400, along with cerave foaming cleanser. I also stopped using sunscreen from september. A week ago I bought back the cerave moisturiser and sunscreen.

When will my skin clear up and what stage is it in?
