I have finally cleared/managed my moderate, persistent adult acne using diet. I've tried accutane (multiple times), antibiotics, Retin-A, benzoyl peroxide etc...

1. No dairy (or casein, whey)
2. No sugar
3. No/low fodmaps
4. No/low carb (sweet potatoes/rice okay)
5. Nicotinamide Riboside supplement
6. Water
7. 16 hour intermittent fasting
