INS and acne: This finding is in contrast with recent studies that have shown a significant association between acne and high glycemic load diets.14 Indeed, high sugar levels have been shown to increase insulin and IGF1 release, leading to androgen secretion, sebum overproduction, and keratinocyte proliferation.15,16 The hormones found in milk can also increase IGF1 levels.17 In our study, 46% of participants reported a daily consumption of dairy products equivalent to one glass of milk, which is low compared to other studies.
