Illness & Symptoms
Acne
Is this your child's symptom?
- Pimples and blackheads on the face caused by blocked oil glands
 
- If NOT, try one of these: 
 - Newborn Rashes and Birthmarks
 - Rash or Redness - Localized
 
Symptoms of Acne
- Whiteheads (pimples) are plugged oil glands that are closed.
 - Blackheads are plugged oil glands that are open. Reason: the oil turns black when it is exposed to air.
 - Whiteheads and blackheads are also called "zits."
 - Red bumps are from blocked oil glands that have leaked oil. This causes irritation in the skin around them. Larger red bumps can be quite painful.
 - Acne mainly appears on your face, neck, and shoulders
 
Causes of Acne
- Acne skin changes are from plugged oil glands. Acne has several causes.
 - Increased levels of hormones during puberty have a part. Heredity also plays an important role.
 - Some skin bacteria can make it worse.
 - Acne is not caused by diet. You do not need to avoid eating fried foods, chocolate, or any other food.
 - Acne is not caused by dirt or by not washing your face often enough.

Care Advice for Acne
What You Should Know About Acne:
- More than 90% of teenagers have some acne. Acne is a normal part of the teen years.
 - There is no medicine at this time that will cure acne.
 - However, good skin care can keep acne under control and at a mild level.
 - Here is some care advice that should help.
 
Benzoyl Peroxide Gel:
- Benzoyl Peroxide (BP) is the best OTC medicine for bringing acne under control. Use a Benzoyl Peroxide 2.5% gel product (such as the store brand). OTC means no prescription is needed.
 - It helps to open pimples and to unplug blackheads. It also kills bacteria.
 - Apply the lotion once a day at bedtime to the area with acne. Redheads and blonds should apply it every other day for the first 2 weeks. Reason: more sensitive skin.
 - Use an amount of lotion the size of a pea. This should be enough to cover most of the acne.
 - If the skin becomes red or peels, use less of it. Other option: You can use it less often.
 - Caution: avoid the corners of the eyes, nose and mouth. Reason: these areas are very sensitive.
 - Caution: Benzoyl Peroxide bleaches clothing, towels, blankets, etc. Apply it only at bedtime and put it on sparingly. Use a plain white pillowcase.
 
Antibiotics for Red Bumps:
- Large red bumps mean the infection has spread beyond the oil gland. If you have several red bumps, your doctor may prescribe an antibiotic.
 - Antibiotics come as solutions for the skin or as pills.
 - The antibiotic will kill the bacteria that are causing the infection.
 - Give the antibiotic as directed.
 
Washing the Face:
- Wash your skin twice a day. The most important time to wash is bedtime. Just use warm water or you can use a mild soap (such as Dove).
 - Shampoo your hair daily.
 - Avoid scrubbing your skin. Reason: hard scrubbing of the skin irritates the openings of the oil glands. This causes them to close off even more tightly.
 
Pimple Opening:
- Opening (popping) pimples is not advised by many doctors. But, most teens and adults do it anyway.
 - So, here's how to open a pimple safely without any squeezing.
 - Never open a pimple before it has come to a head.
 - Wash your face and hands first.
 - Use a sterile needle (cleaned with rubbing alcohol). Nick the surface of the yellow pimple with the tip of the needle. The pus should run out without squeezing.
 - Wipe away the pus and wash the area with soap and water.
 - Opening small pimples in this way will not cause skin damage.
 
Avoid Picking or Squeezing Acne:
- Many young people pick at their acne when they are not thinking about it. Picking makes acne worse.
 - Try not to touch the face at all during the day.
 - Squeezing blackheads causes bleeding into the skin. The bleeding turns into brownish blotches on the skin. They can take 1 or 2 months to fade.
 - Squeezing red lumps can force bacteria into the skin. This too leaves blotches. It can also cause a serious face infection.
 
Prevention - Avoid Triggers of Acne:
- Avoid putting any oily or greasy substances on your face. Reason: They block oil glands and make acne worse. If you use cosmetics, use water-based cosmetics.
 - Avoid hair tonics or hair creams (especially greasy ones). When you sweat, they will get on the face and irritate the acne.
 
What to Expect:
- With treatment, new whiteheads and blackheads will decrease. But, it takes 6 to 8 weeks.
 - Acne usually lasts until age 20 or 25.
 - So, you will need to continue the treatment for several years.
 - You don't need to worry about scarring. It is very rare for acne to leave any scars.
 
Call Your Doctor If:
- With treatment, the acne has not improved after 2 months
 - It looks infected (large, red, tender bumps)
 - You think your child needs to be seen
 - Your child becomes worse
