I have (or I should say had) cystic acne. I woke up one day and had them on my face! One day my face was clear, the next it was not - it was a nightmare. I had never really had a problem with Acne when I was a teen. Within two hours after eating peanuts the Acne would flare. I found this out really quickly. I did a couple experiments myself to figure out what else causes my Acne - all food related. My face is doing much better now that I try to refrain from these foods and also using a niacinamide topical (vitamin B3) on my face that I get from a compounding pharmacy. I will have to try the melons and I already know I should stay away from sweets.
My mother kept telling me to go to a dermatologist to help clear up my face. I know that they only medicate the symptoms not the cause. Thanks for the input!
