 diet is a huge, huge factor. It's often diets that are high in sugar, high in animal fats or refined carbohydrates. So people that have a diet that really messes with their blood sugar is often sort of the precursor for having problem skin, particularly in terms of oily skin, excessive sebum production, and then acne. I think, you know, a testimony to that is that people that do things like intermittent fasting or adopt a low-glycemic load or low-glycemic index diet often find that their skin problems, in relation to acne, particularly, really clear up.
