Acne

What is acne?

Acne is a skin condition that occurs when the oil-secreting glands in the skin are clogged and become inflamed or infected. Ninety percent of teenagers get acne.

How does acne occur?

Acne is caused by inflammation of the oil glands in the skin and at the base of strands of hair. In the teenage years, hormones stimulate the growth of body hair, and the oil glands secrete more oil. The skin pores become clogged and bacteria grow in the clogged pores. When the body works to kill the bacteria, whiteheads and blackheads form in these areas.

How is acne treated?

Treatment is aimed at cleaning out the pores, keeping oil and dirt out of the pores, and reducing inflammation.

First you and your doctor will talk about how you are currently taking care of your skin. You will discuss which products, such as soaps and lotions, you should continue using and which you should stop using.

Several products may be used to help prevent pimples or blackheads. Treatment usually begins with putting products containing benzoyl peroxide on the areas of skin with acne. If benzoyl peroxide alone is not effective, then you may also put antibiotic medications on your skin or your doctor may prescribe antibiotics to be taken by mouth. You may also need to use a skin cream or gel containing tretinoin (Retin-A).

An oral medication called isotretinoin (Accutane) is available for severe acne. However, isotretinoin must be used very carefully because it causes birth defects in babies born to mothers who become pregnant while they are taking the drug or who have taken it 1 or 2 months before becoming pregnant.

Large cysts may be injected with medicine by your doctor so there is less scarring.

How long will the effects last?

New whiteheads usually stop appearing after 4 to 6 weeks of treatment, but usually you will need to continue the treatment at least 6 to 8 weeks. If you are taking antibiotics, at some point your doctor will ask you to stop taking them to see if they are still necessary.

Many factors may make acne worsen temporarily. For example, women may notice that their acne gets worse before each menstrual period. Thus, even if you are receiving the proper treatment, results may vary over time. Try to discover and change, when possible, the factors in your environment or lifestyle that make the acne worse.
