Why do my zits get bigger, then smaller, but never really go away?

Answer 1

If you eat greasy foods, your skin is greasier and acne forms. If you want to get rid of your acne, eat healthily or use acne cream or astringent. I use Clean & Clear Deep Cleaning Astringent that cleans oil from your pores and makes acne disappear in a few days.
Also, make sure they're actually zits...you may want to see your doctor if this is a serious problem.
