There is a bacteria that normally lives on the skin called Propionibacterium acnes. This bacteria lives on the sebum produced by the skin oil glands. Sometimes, this bacteria multiplies and causes inflammation and acne.
Foods generally do not cause acne. In some people, certain foods will make acne worse. The most common ones are chocolate, nuts, carbonated beverages, and milk. Most people's acne is not aggravated by these foods.

Acne is a common skin disorder characterized by clogged pores and pimples.

More than four out of five people between the ages of 12 and 24 have acne at least once. But while the disorder is often associated with teenagers, it can affect people of all ages. It's not uncommon for acne to occur in people in their 20s and 30s. And, some people continue to have acne in their 40s and 50s. Many adult women experience mild to moderate acne due to hormonal changes associated with pregnancy, their menstrual cycles, or starting or stopping birth control pills.

Acne is rarely a serious medical condition, but it often causes emotional distress and can lead to scarring of the skin. With the right treatment, you can often keep acne under control. Measures also can be taken to reduce scars left by acne.
