INS and acne: Many studies have demonstrated the importance of the glycemic load (GL) of foods in acne patients, showing that patients who have low-glycemic index (GI) foods in their daily diet have reduced acne lesions and post-acne percussions, as compared to those patients who have high-GL foods in their daily routine because high-GL carbohydrate intake is readily absorbed, resulting in high blood glucose and higher insulin production [6].
