There exists a surprising link between your plate and face. What you eat can directly affect your skin. High-glycemic foods, which suddenly raise blood sugar, may activate acne in some individuals. 
 

This occurs through increased insulin and insulin-like growth factor-1 (IGF-1) promotion, stimulating sebum production and inflammation. Several such studies have documented the increase in breakouts among individuals with acne who are on a low-glycemic diet when they start consuming sugary foods.

Though diet is not solely to blame for acne, understanding this link could give further options for maintaining skin health regarding conventional treatments.
