It’s been a source of debate for years whether drinking milk can actually cause pimples, but more and more research is indicating a link between milk and acne. For some individuals who have chosen to eliminate milk from their diet, it’s paying off in the form of clearer skin.
Foods with a high glycemic index (which are absorbed into the bloodstream quickly) are also thought to have a direct effect on the severity of acne because they trigger hormonal fluctuations. Common high GI foods include white bread, white rice, many breakfast cereals, bagels, potatoes, etc. Try cutting back on these, and see if your skin gets better.
