| Oral Contraceptives and Acne
What is acne?
Acne, also called "zits" or
"breaking out," usually consists of different types of bumps on the skin. The
most common are pimples, blackheads, and whiteheads. Severe acne can cause deeper bumps,
called cysts or nodules. Acne can appear on the face, neck, shoulders, chest, and upper
back. Acne ranges from mild to very severe. Severe cases of acne can cause permanent
scars.
How common is acne?
Acne is a common condition affecting about 17
million Americans. Acne occurs most often among teenagers - nearly 4 out of every 5 teens
have acne. The condition usually first appears between the ages of 10 and 13. In most
cases, acne lasts for about 5 to 10 years, then goes away on its own. However, some adults
in their 20's, 30s, and even 40s get acne.
What causes acne?
Acne occurs when pores in the skin become
clogged with a mixture of oil and dead skin cells. The oil (called sebum) is created by
glands at the base of each pore. Normally, this oil travels up through the pore and out
onto the surface of your skin. However, if too much oil is produced, it can cause the
cells in the pore lining to make a plug at the skin's surface. Germs can grow below the
plug, causing redness, swelling, and pimples. Blackheads form when the plug goes though a
chemical process - they are not caused by dirt.
How do hormones affect
acne?
Certain hormones produced by your body can
make the skin glands more active, causing them to put out more oil. You are more likely to
develop acne during times when your body makes larger amounts of the hormones, such as
during puberty. This is why so many teenagers get acne.
Will using oral
contraceptives make my acne better or worse?
Most women find that their acne improves when
using oral contraceptives ("the pill"). The overall hormonal effect of the pill
helps prevent acne from forming, which is why birth control pills often are used as a
treatment for acne.
What can I do to
prevent acne or keep it from getting worse?
In most cases, acne is caused by your hormones
- not by dirt or oil or foods - which makes it difficult to prevent. It is important to
know that washing or scrubbing your face will not help acne. In fact, scrubbing too hard
or washing too often can actually make your acne worse. Also, do not squeeze your pimples
or pick at your skin; this can cause acne to spread and could result in permanent scars.
If you use make-up or sunscreen, choose oil-free products labeled
"non-comedogenic" or "non-acnegenic."
What treatments are
available for acne?
Mild to moderate acne can be treated with a
variety of over-the-counter (nonprescription) products, such as lotions and creams
containing benzoyl peroxide. These products come in different strengths, usually 2.5%, 5%,
and 10%. Benzoyl peroxide might make your skin red or dry. If your skin starts to peel,
try using a lower-strength formula or use it less often. Benzoyl peroxide can bleach your
hair or clothing, so be careful when using it near your hair or in areas that will come in
contact with your cloths.
A variety of acne treatments are available by
prescription. Your doctor may prescribe antibiotics, either to be applied directly on the
skin or to be taken orally, or retin A products. Some prescription drugs for severe acne
can cause birth defects in babies, so avoiding pregnancy is very important if you are
taking certain medications. Discuss this with your clinician.
For moderate to severe acne, birth control
pills are often prescribed as a treatment. This approach can be especially useful if you
also want to avoid pregnancy. None of the birth control pills available in the United
States have been shown to be better than any other pills for the treatment of acne. Be
sure to discuss the situation with your clinician - he or she can help you select the
right treatment for your acne.
Lastly, be patient: Most acne treatments
take several months to work. It is important to continue using the medication as
recommended throughout the treatment period. |
