What is acne?
Acne, or acne vulgaris, is
a skin problem that starts when oil and dead skin cells clog up your pores.
Some people call it blackheads, blemishes, whiteheads, pimples, or zits. When
you have just a few red spots, or pimples, you have a mild form of acne. Severe
acne can mean hundreds of pimples that can cover the face, neck, chest, and
back. Or it can be bigger, solid, red lumps that are painful (cysts).
Acne is very common among teens. It usually gets better after
the teen years. Some women who never had acne growing up will have it as an adult, often right before their
How you feel about your acne may not be related
to how bad it is. Some people who have severe acne are not bothered by it. Others
are embarrassed or upset even though they have only a few pimples.
The good news is that there are many good treatments that can help you
get acne under control.
For most people, acne starts during the teen
years. This is because hormone changes make the skin oilier after puberty
Using oil-based skin products or cosmetics can make acne worse. Use skin products that don't clog your pores. They will say "noncomedogenic" on the label.
Acne can run in families. If one of your parents had severe
acne, you are more likely to have it.
What are the symptoms?
Symptoms of acne include
whiteheads, blackheads, and
pimples. These can occur on the face, neck, shoulders,
back, or chest. Pimples that are large and deep are called
cystic lesions. These can be painful if they get
infected. They also can scar the skin.
How is acne treated?
To help control acne, keep
your skin clean. Avoid skin products that clog your pores. Look for products
that say "noncomedogenic" on the label. Wash your skin once or twice a day with
a gentle soap or acne wash. Try not to scrub or pick at your pimples. This can
make them worse and can cause scars.
If you have just a few
pimples to treat, you can get an acne cream without a prescription. Look for
one that has benzoyl peroxide or salicylic acid. These work best when used just
the way the label says.
It can take time to get acne under
control. But if you haven't had good results with nonprescription products after trying them for 3 months, see your doctor. A prescription gel or skin cream may be all you need. If you are a woman, taking certain birth control pills may help.
you have acne cysts, your doctor may suggest a stronger medicine, such as isotretinoin. This medicine works very well for some kinds of acne.
What can be done about acne scars?
There are many skin
treatments, such as laser resurfacing or dermabrasion, that can help acne scars look better and feel smoother. Ask your
doctor about them. The best treatment for you depends on how severe the
scarring is. Your doctor may refer you to a plastic surgeon.
different types of acne. The most common
acne is the type that develops during the teen years.
Puberty causes hormone levels to rise, especially
testosterone. These changing hormones cause skin glands
to start making more oil (sebum). Oil releases from the pores to protect the
skin and keep it moist. Acne begins when oil mixes with dead cells and clogs
the skin's pores. Bacteria can grow in this mixture. And if this mixture leaks
into nearby tissues, it causes swelling, redness, and pus. A common name for
these raised bumps is
Certain medicines, such as corticosteroids or lithium, can cause acne to develop. Talk to your doctor about any medicines you are taking.
It isn't just
teens who are
affected by acne. Sometimes newborns have acne because
their mothers pass hormones to them just before delivery. Acne can also appear
when the stress of birth causes the baby's body to release hormones on its own.
Young children and older adults also may get acne.
Severe acne can produce hundreds of pimples that cover large areas of
Cystic lesions are pimples that are large and deep.
These lesions are often painful and can leave scars on your skin.
Acne can lead to low self-esteem and sometimes
depression. These conditions need treatment along with
Acne develops most often in the teen and young adult
years. During this time, both males and females usually produce more
testosterone than at any other time in life. This
hormone causes oil glands to produce more oil (sebum). The extra oil can clog
pores and cause acne. Bacteria can grow in this mixture. And if the mixture
leaks into nearby tissues, it causes swelling, redness, and pus
Acne usually gets better in the adult years when your
body produces less testosterone. Still, some women have
premenstrual acne flare-ups well into
What Increases Your Risk
The tendency to develop
acne runs in families. You are more likely to develop
severe acne if your parents had severe acne.
The risk of
developing acne is highest during the teen and young adult years. These are the
years when hormones such as
testosterone are increasing. Women who are at the age
menstruation also are more likely to develop acne.
Many women have acne flare-ups in the days just before their menstrual
Acne can be irritated or made worse by:
Wearing straps or other tight-fitting items
that rub against the skin (such as a football player wearing shoulder pads), as
well as using equipment that rubs against the body (such as a violin held
between the cheek and shoulder). Helmets, bra straps, headbands, and turtleneck
sweaters also may cause acne to get worse.
Using skin and hair care
products that contain
Washing the face
too often or scrubbing the face too hard. Using harsh soaps or very hot water
can also cause acne to get worse.
Experiencing a lot of
Touching the face a lot.
Having hair hanging in the face, which can cause the skin to
Watchful waiting is a wait-and-see approach. If
you get better on your own, you won't need treatment. If you get worse, you and
your doctor will decide what to do next.
Mild acne, with a few pimples that clear up on their own, may not need any treatment. But if you are worried about how much you are breaking out, see your doctor. Getting medical treatment early may prevent acne from getting worse or from causing scars.
If you have severe acne, if your acne does not clear up with home treatment, or if you develop acne scars,
call your doctor.
Who to see
The following health professionals can
diagnose and treat acne:
When you see a doctor about
acne, you'll have a
physical exam, and your doctor will ask about your
medical history. Women may be asked questions about
their menstrual cycles. This information can help your doctor find out if
hormones are playing a role in acne flare-ups. Most often, you won't have any
special tests to diagnose acne.
You may need other tests if your
doctor suspects that acne is a symptom of another medical problem (such as
higher-than-normal amounts of
testosterone in a woman).
depends on whether you have a
mild, moderate, or severe type of acne. Sometimes your doctor
will combine treatments to get the best results and to avoid developing
drug-resistant bacteria. Treatment could include
lotions or gels you put on blemishes or sometimes entire areas of skin, such as
the chest or back (topical medicines). You might also take medicines by mouth
Treatment for mild acne (whiteheads, blackheads, or pimples) may
Gentle cleansing with warm water and a mild soap, such as
Dove or Cetaphil.
If these treatments do not work, you may want to see your
doctor. Your doctor can give you a prescription for stronger lotions or creams.
You may try an
antibiotic lotion. Or you may try a lotion with
medicine that helps to unplug your pores.
Moderate to severe acne
Sometimes acne needs treatment with stronger
medicines or a combination of therapies. Deeper blemishes, such as nodules and
cysts, are more likely to leave scars. As a result, your doctor may give you
oral antibiotics sooner to start the healing process. This kind of acne may
need a combination of several therapies. Treatment for moderate to severe acne
Taking prescription oral retinoids (such as
Treatment for acne scars
There are many procedures to remove acne scars, such as laser resurfacing and dermabrasion. Some scars shrink and fade with time. But if your scars bother you, talk to your doctor. He or she may refer you to a dermatologist or a plastic surgeon.
What to think about
Most treatments for acne take time. It often
takes 6 to 8 weeks for acne to improve after you start treatment. Some treatments may cause acne to get worse before it gets
If your acne still hasn't improved after several tries with
other treatment, your doctor may recommend that you take an oral retinoid, such
as isotretinoin. Doctors prescribe this
medicine as a last resort, because it has some rare but serious side effects
and it is expensive.
Certain low-dose birth control pills may help
control acne in women who tend to have flare-ups before menstruation.
Alpha hydroxy acid, which dries up blemishes and
causes the top skin layer to peel. You'll find alpha hydroxy acid in some
moisturizers, cleansers, eye creams, and sunscreens.
Salicylic acid (such as Propa pH or Stridex), which dries up
blemishes and causes the top skin layer to peel.
Tea tree oil, which kills bacteria. You'll find tea tree oil in some gels,
creams, and oils.
Some skin care products, such as those with alpha hydroxy acid, will make your skin very sensitive to ultraviolet (UV) light. Protect your skin from the sun and other sources of UV light.
Medicines can help manage the severity
and frequency of
acne outbreaks. A number of medicines are available.
Your treatment will depend on the type of acne you have (pimples,
whiteheads, blackheads, or
cystic lesions). These medicines improve acne

Reducing the effects of hormones
in producing acne (certain oral contraceptive pills for women).
The best medical treatment for acne often is a combination
of medicines. These could include medicine that you put on your skin (topical)
and medicine that you take by mouth (oral). Or you may take medicines such as clindamycin/benzoyl peroxide, a gel that contains two topical medicines.
Treatment of acne depends on whether
inflammation or bacteria are present. Some acne
consists only of red bumps on the skin with no open sores (comedonal acne).
Topical creams and lotions work best for this type of acne. But if bacteria or
inflammation is present with open sores, oral antibiotics or isotretinoin may
The most common types of medicines that doctors use
to treat acne include:
Low-dose birth control pills that contain
estrogen (such as Estrostep, Ortho Tri-Cyclen, or
Yaz), which work well on moderate acne in women and for premenstrual flare-ups.
Androgen blockers, such as spironolactone. Androgen
blockers can be useful in treating acne. These medicines decrease the amount of
sebum (oil) made in your pores.
What to think about
If you are pregnant, talk to
your doctor about whether you should take antibiotics for acne. Some
antibiotics aren't safe to take during pregnancy.
bacteria can become resistant to antibiotics, which means that the antibiotics
are no longer effective at killing or controlling the bacteria causing the
acne. This is called
drug resistance. When this occurs, a different
antibiotic may be used.
After acne is under control, you often
need ongoing treatment to keep it from returning. This is the maintenance phase
of treatment. Your doctor may suggest treatments other than antibiotics for
long-term use, to avoid the risk of drug resistance.
medicines usually have fewer and less serious side effects than oral medicines.
But topical medicines may not work as well as oral medicines for severe
Isotretinoin (such as Sotret) and tazarotene
(Tazorac) can have serious side effects. Women who take isotretinoin or
tazarotene need to use an effective birth control method, to avoid having a
baby with serious birth defects.
Photodynamic therapy (PDT) and other light and laser-based therapies are being used to treat acne. These include the use of blue light, red light, intense pulsed light (IPL), and infrared or pulsed dye lasers. Sometimes these therapies are used along with medicines, but they may also help people who cannot be treated with medicines.
