I know this will sound a little crazy at first, but it's worth a try! I had terrible cystic acne on my face and back and after years of trying everything I could think of, I read that nightshades (a class of plant that includes white potatoes, tomatoes, ALL peppers, eggplant, tobacco and a few others. ) can cause this issue so I quit eating them entirely for 2 weeks - TOTALLY cleared up! I had wished someone had told me long before that. So if it helps you, I've paid it forward!
