Way to prevent acne

Contrary to what you may have heard, acne is not caused by dirty skin, eating chocolate, or drinking lots of soda. Acne is caused by overactive oil glands in the skin. These glands become stimulated when puberty hormones become active. Some people have more of a reaction to their hormone levels than others, which is why different people have different levels of acne.

Although there is no surefire way to prevent acne, there are several ways to help reduce the number and severity of your breakouts.

Washing your skin is essential (it helps remove excess surface oils and dead skin cells that can clog your pores), but washing too much can actually cause damage by overdrying your skin or irritating existing acne.

Remember to wash after exercising because sweat can clog your pores and make your acne worse. If you work around greasy food or oil or if you've been sweating from heat or because you've been working hard, wash your face and other acne-prone areas as soon as possible.

If you use skin products, such as lotions or makeup, look for ones that are noncomedogenic or nonacnegenic, which means that they don't clog pores.

If you can't live without your hair spray or styling gel, be sure to keep them away from your face as much as possible. Many hair products contain oils that can make acne worse.

If you get acne on areas such as your chest or back, avoid wearing tight clothes, which can rub and cause irritation.

Treatments:
Some teens find that over-the-counter products can help clear up acne. It may take some time to find the one that works best for you - some may not do the trick and others may cause irritation. Over-the-counter acne products come in different strengths; the typical acne-fighting ingredients are benzoyl peroxide and salicylic acid.

If you find over-the-counter products aren't working for you, it's best to seek a doctor's advice. A doctor can prescribe special gels or creams, pills, or a combination of both. It may feel a bit awkward or embarrassing to talk about your acne with someone, especially a stranger, but your doctor is trained to help get your skin looking its best.

What about pimples you already have? It's tempting, but popping or squeezing a pimple usually won't get rid of the problem. Squeezing can actually push infected material and pus further into the skin, which can lead to more swelling and redness (not what you want before a big date!), and even scarring, which can be permanent.

If you are taking a prescription acne medication, finish your entire prescription even if your skin clears up, unless your dermatologist says you can stop. If you stop too early, there's a chance your skin could break out all over again.

Eating nutritious foods can help keep you healthy of course, and your skin will benefit from getting enough vitamins and minerals. But the bottom line is that you don't need to be obsessive about what you eat or how often you wash your face to control acne. If you don't find an over-the-counter product that works for you, talk to your doctor or a dermatologist for some advice on living through the acne years.

Myths About Acne

Myth #1: Tanning clears up skin.
Fact: Although a tan may temporarily mask acne, the sun can make the skin dry and irritated, leading to more breakouts in the future. In fact, there's no link between sun and acne prevention, though the sun's rays can cause premature aging and skin cancer. Always protect your skin by choosing a sunscreen with at least an SPF (sun protection factor) 15 that says noncomedogenic or nonacnegenic on the label, which means it won't clog pores.

Myth #2: Chocolate and greasy foods cause acne.
Fact: Although eating too many sugary, high-fat foods is never a good idea, studies show that no specific food has been proven to cause acne. Every individual is different, though. Some people notice their breakouts are worse after eating certain foods - and these foods are different depending on the person. For example, some people may notice breakouts after eating chocolate, while others are fine with cholcolate but notice they get breakouts after drinking too much coffee. If that's the case for you, it can help to cut back on that food and see if it makes a difference.

Myth #3: The more you wash your face, the fewer breakouts you'll have.
Fact: Although washing your face helps to remove dirt and oil from your pores, washing too much can lead to dryness and irritation, causing more breakouts. Also, avoid scrubbing your face, which can irritate the skin. As a general rule, wash your face twice a day with mild soap and water in a circular motion and gently pat dry when you're done.

Myth #4: Popping pimples will help them go away faster.
Fact: Popping a pimple may make it seem less noticeable temporarily, but popping can cause it to stay around longer. By squeezing pimples and zits, you can actually push bacteria further into the skin, causing more swelling and redness - and sometimes causing a red or brown mark or scar to form. Sometimes marks can last for many months and true scars (dents and pits) will last forever.

Myth #5: Don't wear makeup if you want clear skin.
Fact: As long as you choose cosmetics that are nonacnegenic or noncomedogenic, they shouldn't cause breakouts. In fact, some concealers now contain benzoyl peroxide or salicylic acid, which help to fight acne. You can also try tinted benzoyl peroxide creams that hide pimples while helping treat them.
If you've had moderate to severe acne, though, talk to your doctor or dermatologist about the best cosmetics to use - he or she may recommend avoiding cosmetics altogether or only using certain brands so you're acne isn't aggravated.
And even if a product is labeled nonacnegenic or noncomedogenic, you should stop using it and talk to your doctor if you notice that it's irritating your skin or seems to cause breakouts.

Myth #6: If you keep getting breakouts, it helps to use more acne medication until the breakouts stop.
Fact: Because acne medication contains drying agents like benzoyl peroxide and salicylic acid, using too much medication may cause overdrying, leading to irritation and more blemishes.
If over-the-counter acne medication doesn't seem to work on your acne, it's a good idea to talk to your doctor or dermatologist. Also, if you're taking a prescription acne medication, make sure you follow your doctor's instructions; some medications may take up to 8 weeks to make a significant difference.

Scars from acne

Acne stinks, and it's little comfort to know that everyone gets it. Scars from acne can seem like double punishment - first you had to suffer through the pimples, now you have marks to remind you. Is there anything you can do?

To understand scars, you need to understand acne. Acne refers to lesions or pimples caused when the hair follicles (or "pores") on the skin become plugged with oil and dead skin cells. A plugged follicle is the perfect place for bacteria to grow and create the red bumps and pus-filled red bumps known as pimples. (The usual bacteria that causes acne is called Propionibacterium acnes.) Hormonal changes during the teen years often cause increased oil production that contributes to the problem.

Acne comes in different forms:

mild acne, which refers to the whiteheads or blackheads that most of us get at various times
moderately severe acne, which includes red inflamed pimples called papules and red pimples with white centers called pustules
severe acne, which causes nodules - painful, pus-filled cysts or lumps - to appear under the skin
Most serious scarring is caused by the more severe forms of acne, with nodules more likely to leave permanent scars than other types of acne. The best way to deal with acne is to get treatment soon after the acne appears to prevent further severe acne and more scarring. If you have nodules, see your doctor or dermatologist for treatment.

If you have serious scarring from previous bouts with acne, there are some things you can do. One form of treatment is laser resurfacing, which can be done in the doctor's or dermatologist's office. The laser removes the damaged top layer of skin and tightens the middle layer, leaving skin smoother. This can take anywhere from a few minutes to an hour. The doctor will try to lessen any pain by first numbing the skin with local anesthesia. It usually takes between 3 and 10 days for the skin to heal completely.

Another method for treating acne scarring is dermabrasion, which uses a rotating wire brush or spinning diamond instrument to wear down the surface of the skin. As the skin heals, a new, smoother layer replaces the abraded skin. It may take a bit longer for skin to heal using dermabrasion - usually between 10 days and 3 weeks.

Both of these types of treatments will cause skin to turn red, and this redness may last for several months. You can only have these treatments if you don't have an active case of acne at the time of treatment.

Depending on the severity of your scars, your doctor or dermatologist may also suggest a more mild chemical peel or microdermabrasion, which are also done right in the office, to help improve the appearance of the scarred areas.

In some cases, a doctor may recommend surgery to remove deeply indented scars.

One thing you shouldn't do to deal with acne scars is load up your face with masks or fancy lotions - these won't help and may irritate your skin further, making the scars red and even more noticeable.

If you have a red or brownish mark on your face that you got from a bad zit, have no fear - it will eventually fade, just like the scars you had on your knees after you fell off your bike when you were a kid. However, it may take 12 months or longer - so your best bet is to avoid these kinds of marks by not squeezing or popping your zits, no matter how tempting it may seem.

What Is Acne and What Causes It?

If you're a teen, chances are pretty good that you have some acne. Almost eight in 10 teens have acne, along with many adults.

Acne is so common that it's considered a normal part of puberty. But knowing that doesn't always make it easier when you're looking at a big pimple on your face in the mirror. So what is acne, and what can you do about it?

What Is Acne and What Causes It?
Acne is a condition of the skin that shows up as different types of bumps. These bumps can be blackheads, whiteheads, pimples, or cysts. Teens get acne because of the hormonal changes that come with puberty. If your parents had acne as teens, it's more likely that you will, too. The good news is that, for most people, acne goes away almost completely by the time they are out of their teens.

The type of acne that a lot of teens get is called acne vulgaris (the meaning of "vulgaris" isn't as bad as it sounds - it means "of the common type"). It usually shows up on the face, neck, shoulders, upper back, and chest.

The hair follicles, or pores, in your skin contain sebaceous glands (also called oil glands). These glands make sebum, which is an oil that lubricates your hair and skin. Most of the time, the sebaceous glands make the right amount of sebum. As a teen's body begins to mature and develop, though, hormones stimulate the sebaceous glands to make more sebum, and the glands may become overactive. Pores become clogged if there is too much sebum and too many dead skin cells. Bacteria (especially a bacteria called Propionibacterium acnes) can then get trapped inside the pores and multiply, causing swelling and redness - the start of acne.

If a pore gets clogged up and closes but bulges out from the skin, you're left with a whitehead. If a pore gets clogged up but stays open, the top surface can darken and you're left with a blackhead. Sometimes the wall of the pore opens, allowing sebum, bacteria, and dead skin cells to make their way under the skin - and you're left with a small, red bump called a pimple (sometimes pimples have a pus-filled top from the body's reaction to the bacterial infection). Clogged pores that open up very deep in the skin can cause nodules, which are infected lumps or cysts that are bigger than pimples and can be painful.

There are a few myths out there about things that cause acne. Acne isn't caused by eating greasy foods like french fries or pizza, chomping on chocolate, or drinking sodas. Some people do find that they notice their breakouts get more severe when they eat too much of a certain food, though. If you're one of them, it's worth trying to cut back on that food to see what happens.

Stress doesn't usually cause acne either (although it can make existing acne worse because stress increases sebum production).

There are also myths about what helps make acne better. Acne isn't really helped by the sun. Although a tan can temporarily make acne look less severe, it won't help it go away permanently - and some people find that the oils their skin produces after being in the sun make their pimples worse.

What Can I Do About Acne?
To help prevent the oil buildup that can contribute to acne, wash your face twice a day with a mild soap and warm water. Don't scrub your face hard with a washcloth - acne can't be scrubbed away, and scrubbing may actually make it worse by irritating the skin and pores. Try cleansing your face as gently as you can.

If you wear makeup or sunscreen, make sure it's labeled "oil free," "noncomedogenic," or "nonacnegenic." This means it won't clog your pores and contribute to acne. And when you are washing your face, be sure you take the time to remove all of your makeup so it doesn't clog your pores.

If you use hair sprays or gels, try to keep them away from your face, as they can also clog pores. If you have long hair that touches your face, be sure to wash it frequently enough to keep oil away. And if you have an after-school job that puts you in contact with oil - like in a fast-food restaurant or gas station, for example - be sure to wash your face well when you get home. It can also help to wash your face after you've been exercising.

There are many over-the-counter lotions and creams containing salicylic acid or benzoyl peroxide available to help prevent acne and clear it up at the same time. You can experiment with these to see which helps. Be sure to follow the instructions exactly - don't use more than you're supposed to at one time (your skin may get too dried out and feel and look worse) and follow any directions to see if you're allergic to it first.

What if I Get Acne Anyway?
Sometimes even though they wash properly and try lotions and oil-free makeup, people get acne anyway - and this is totally normal. In fact, some girls who normally have a handle on their acne may find that it comes out a few days before they get their period. This is called premenstrual acne, and about seven out of 10 women get it from changes in hormones in the body.

Some teens who have acne can get help from a doctor or dermatologist (a doctor who specializes in skin problems). A doctor may treat the acne with prescription medicines. Depending on the person's acne, this might mean using prescription creams that prevent pimples from forming, taking antibiotics to kill the bacteria that help create pimples, or if the acne is severe, taking stronger medicines such as isotretinoin or even having minor surgery. Some girls find that birth control pills help to clear up their acne.

If you look in the mirror and see a pimple, don't touch it, squeeze it, or pick at it. This might be hard to do - it can be pretty tempting to try to get rid of a pimple. But when you play around with pimples, you can cause even more inflammation by poking at them or opening them up. Plus, the oil from your hands can't help! More importantly, though, picking at pimples can leave tiny, permanent scars on your face.
