Acne is a skin disease that affects individuals of all ages, especially teenagers who begin puberty. Based on the research of Robyn N Smith shown that the subject with a low-glycemic-load diet was shown a significant reduction of acne lesion counts and improvement of insulin sensitivity when compared subject with a high-glycemic-load diet. These findings are consistent with earlier suggestions of the association between hyperinsulinemia and acne. According to the research of Jennifer Burris, Glycemic Index and Glycemic Load are implicated in acne pathogenesis due to diet-induced hyperinsulinemia, stimulating an increase in insulin-like growth factor (IGF-1) concentrations and androgen hormones, thus resulting in amplifying acne-promoting pathways.
