Acne vulgaris; Cystic acne; Pimples; Zits
Acne is a skin condition that causes pimples or "zits." Whiteheads, blackheads, and red, inflamed patches of skin (such as cysts) may develop.
Acne occurs when tiny holes on the surface of the skin become clogged. These holes are called pores.
Acne is most common in teenagers, but anyone can get acne, even babies. The problem tends to run in families.
Some things that may trigger acne include:
Research does not show that chocolate, nuts, and greasy foods cause acne. However, diets high in refined sugars or dairy products may be related to acne in some people, but this connection is controversial.
Acne commonly appears on the face and shoulders. It may also occur on the trunk, arms, legs, and buttocks. Skin changes include:
Your health care provider can diagnose acne by looking at your skin. Testing is not needed in most cases. Bacterial culture may be performed with certain patterns of acne or to check for infection if large pus bumps persist.
Steps you can take to help your acne:
What NOT to do:
If these steps do not clear up the blemishes, try over-the-counter acne medicines that you apply to your skin. Follow the directions carefully and apply these products sparingly.
A small amount of sun exposure may improve acne slightly, but tanning mostly hides the acne. Too much exposure to sunlight or ultraviolet rays is not recommended because it increases the risk for wrinkles and skin cancer.
MEDICINES FROM YOUR PROVIDER
If pimples are still a problem, your provider can prescribe stronger medicines and discuss other options with you.
Antibiotics may help some people with acne:
Creams or gels applied to the skin may be prescribed:
For women whose acne is caused or made worse by hormones:
Minor procedures or treatments may also be helpful:
People who have cystic acne and scarring may try a medicine called isotretinoin. You will be watched closely when taking this medicine because of its side effects.
Pregnant women should NOT take isotretinoin, because it causes severe birth defects.
Most of the time, acne goes away after the teenage years, but it may last into middle age. The condition often responds well to treatment, but responses may take 6 to 8 weeks, and acne may flare up from time to time.
Scarring may occur if severe acne is not treated. Some people become very depressed if acne is not treated.
Contact your provider if:
If your baby has acne, contact the baby's provider if acne does not clear up on its own within 3 months.
