Zinc is one of the longest-studied nutrients that correlates with statistically significantly less acne. Some months ago‚ I discovered that around 200mg/day of zinc picolinate could‚ under some circumstances‚ make me dramatically acne-free for the first time ever. That led to a very long course of study‚ research and experiments. For a megadose of zinc to affect acne dramatically‚ a good bet was that zinc is a cofactor in a reaction that affects acne. If you have a chemical reaction in the body
