I'm so sorry to hear that. Yes, you can consume less fried foods and eat more organic and home-cooked foods if you aren't already. I would recommend some form of physical activity like walking running etc. Also, increase your water intake to a minimum of 3 liters of more daily. Good stress management techniques can also be helpful. These methods need to be practiced consistently and long-term for them to have a good impact.
I would recommend you to consult a dermatologist for this condition as well.
