Due to the presence of hormones, your oil glands go into overdrive. They produce extra oil, which block your follicles and clump together with the dead skin cells on the top layer of your skin. When this sticky mixture works its way into your pores, it acts just like a cork in a bottle — trapping oil and bacteria inside. Unfortunately, your oil glands cannot determine when to stop so they keep producing oil thus making the follicle swollen. Your body’s natural defense system — white blood cells — rush to the area to produce an enzyme that damages the wall of the follicle, allowing the contents of the follicle to enter the dermis. This process causes an inflammatory response that results in either red, painful bumps (papules); blackheads and whiteheads (comedones); pimples or acne. Contrary to common belief, this condition has nothing to do with what you eat, or how often you wash your face.

Dermatologists point out that dietary factors neither cause nor cure acne. In almost all cases, the food you eat has almost nothing to do with your acne, except for those containing iodine and muscle-enhancing steroids. If you ingest a large amount of iodine like mineral pills, your acne will likely flare up. Steroids have also been known to cause a type of acne referred to as steroid acne.
