what I've seen helped several people,including me,is "Brewer's Yeast"
=whole range of Vitamine B's(health food store)Strangely,I never see it mentioned on curezone in aiding acne.
If the directions say on the bottle for instance "take 3-6 pills 3 times a day",I would double that amount to 6-9 3times a day
Try it for a minimum of 14 days
Increase intake of clean water
Hope this will help you
