Summary

For years dermatology insisted "diet has nothing to do with acne" — that was wrong: **high-glycaemic-load diets and dairy (especially skim milk and whey protein) genuinely worsen acne** through an insulin/IGF-1 → androgen → sebum pathway, so the highest-yield levers are lowering glycaemic load and trialling dairy reduction — while the old myths (chocolate, greasy food, "dirty skin") remain myths.
