Try to get as all-natural as possible. The big acne gurus will suggest that diet is not a factor in acne and it very well may not be. But, the chemical preservatives, parabens, sulfates, and phosphates in your food, drinks, and personal care products may be a cause of acne. Other, less “civilized" cultures, who do not eat as many refined or processed foods and who use natural personal care products, do not experience acne or pimples like Americans.
