How to manage skin after Accutane?

Ever since I ended accutane, my skin has been very dull, the skin tone and texture is very uneven, I have a lot of hyperpigmentation, and I've developed wrinkles on my forehead. I can't afford super expensive treatments, but I was wondering if y'all could recommend products or affordable treatments to help my concerns? I have black skin so what works for a white person in regards to uneven skin tone may work differently for me, so please take that into consideration.
