I am a teenager, 17 years old, and I have acne. I have a clean diet. I have completely stopped eating sugar and carbohydrates. I even took Roaccutane, but it didn't work. I tried all kinds of creams and lotions, but some didn't work.I am a teenager, 17 years old, and I have acne. I have a clean diet. I have completely stopped eating sugar and carbohydrates.
