What is gilbert's syndrome & acne?

Unrelated. Maybe 4% of people have gilbert's, a mild treatment-worse-than-the-disease kink in bilirubin metabolism that's usually just a glitch on a lab report; you can confirm it (if you think it's worthwhile) by going hungry for a day or two -- gilbert's folks get a little jaundiced. It's unrelated to your acne -- today all acne is treatable with prescription medications. Glad you're proactive, good luck.
