Almost all teenagers get acne at one time or another. Pimples are caused when oil ducts in the skin get plugged up and then burst, causing redness and swelling. Although there are many myths about acne, the following are the three main factors that cause it.


1. Hormones


   When a child begins puberty, certain hormones, called androgens, increase in both males and females. These hormones trigger oil ducts on the face, back and upper chest to begin producing oil. This can cause acne in some people.



2. Heredity


   If other members of the family had acne as teenagers, there may be a chance that you've inherited a tendency toward getting acne as well.



3. Plugged oil ducts


   If a teen is prone to acne, the cells that line the oil ducts in the skin tend to get larger and produce more oil, and the ducts get plugged. This traps the oil and leads to the formation of blackheads or whiteheads. The plugged ducts allow germs in the skin to multiply and produce chemicals that cause redness and swelling. This is why simple blackheads and whiteheads may turn red and bumpy and turn into pimples or acne.



There is not much that can be done about heredity, so the best efforts to control acne are those that keep the oil ducts unplugged.



                What doesn't cause acne?


                       - Acne is not caused by foods you eat. Despite what you may have heard, there is no proof that soft drinks, chocolate and greasy foods cause acne.


                       - It's not caused by dirt. The black plug in a blackhead is caused by a chemical reaction. It's not dirt. No matter how carefully you wash your face, you can still have acne.


                       - It's not something you can catch or give to another person.


             


               If you have acne, there are some things that can make it worse. To keep acne under control, try to avoid the following:


                       - Pinching or popping pimples, which forces oil from the oil ducts into the surrounding normal skin, causing redness and swelling


                       - Harsh scrubbing, which irritates the skin


                       - Things that rub on the skin, such as headbands, hats, hair and chin straps, which also cause irritation


                       - Certain cosmetics, such as creams and oily hair products, which can block oil ducts and aggravate acne


                       - Some medications


                       - For young women, changes in hormone levels brought on by menstrual periods


                       - Emotional stress and nervous tension
