You can try proactiv but it didn't work for me so don't be disappointed if you got it and it didn't work. I have never heard of exercising making your skin better. I had really bad skin when I was young and I had to take something called tetracycline internally because my acne was caused by a hormone imbalance. See a dermatologist. He can give you something stronger for your acne and he can give you something to minimize scarring. They even sell products over the counter that are for scarring. Drinking lots of water is good for the skins. Don't believe myths that what you eat and drink affects your skin. That isn't true. My daughter is a human garbage disposal and her skin is flawless.How to get rid of acne and its scars???what should be the min water intake to get rid of it?
