I Have Been Experiencing Acne And Or Roseacea On My

I have been experiencing acne and or roseacea on my face since puberty. almost 40 years. I have been able to control it using benzoyl peroxide night and day. This has become such a battle to keep under control. I have been wondering about a more reliable solution long term. I have been told by medical personnel that taking pills to control this condition can harm the liver. This condition is genetic. I have oily skin anyway, and try to avoid oils, sugar and yogurt, since sugar causes inflammation and yogurt contains bacteria. Any suggestions?
