I've had dark circles under my eyes for my entire life. It seems that two of the main causes of dark circles are wheat and dairy allergies. As part of a lifestyle change, I completely cut out wheat from my diet about three months ago. Now that I know wheat isn't the cause, I'm going to cut out dairy to see if anything changes. I'm just wondering how long it might be before my raccoon eyes start to go away, assuming that they are actually caused by some sort of dairy allergy? Two weeks, a month, two months?
