While the ingredients listed above are what you can put together in a diet to get rid of acne in a week, there are certain foods that count as bad food for acne as well. To benefit from what is good for your acne and skin, you must make sure the bad stays out. Greasy food and junk food, dairy products, and high sugar processed foods can trigger the inflammation of your pores. Including more greens, fruits, whole grains, and even chocolate are how you feed your skin the good stuff.
