Dietary influences on acne have been explored by several clinical studies. Preliminary evidence suggests that dairy products influence the development and severity of acne through the actions of Insulin-like growth factor 1. Additional studies suggest that high-glycemic diets impact acne. Omega-3 fatty acid supplementation influences on acne show conflicting results. Further large-scale clinical studies are needed to definitively explore the influence of diet on the development of acne. Providers should consider assessing dietary patterns in patients with acne and counsel those individuals who are found to intake diets that might adversely affect acne.
