Damage to facial skin caused by overconsumption of caffeine and processed and sugary foods for over a year?

I have been drinking A LOT of coffee for more than a year (I stopped few months ago). That is all I used to drink all day, and junk food on weekends. Caffeine made me urinate a lot. Now, my problem is, it left my face totally dried, with A LOT of deep wrinkles under the eye, and very deep dark circles, they all are really apparent, and they look really bad! And my skin texture has completely changed!!! I look SO old! I had zero wrinkles before! What can I do?
