Acne

Acne

Acne (acne vulgaris, common acne) is a disease of the hair follicles of the face, chest, and back that affects almost all males and females during puberty; the only exception being teenage members of a few primitive isolated tribes living in Neolithic societies.

 

It is not caused by bacteria, although bacteria play a role in its development. It is not unusual for some women to develop acne in their mid- to late-20s.

 

You can do a lot to treat your acne using products available at a drugstore or cosmetic counter that do not require a prescription. However, for tougher cases of acne, you should consult a physician for treatment options.

 

Because acne typically occurs during a time of dramatic physical and psychological changes associated with the development of one's body image, it can exacerbate social withdrawal and even depression. Left untreated, severe acne can lead to disfiguring scarring which can be difficult to treat.

 

Several myths exist about acne.

 

  1. Acne is not a result of uncleanliness or infrequent washing. In other words, acne does not result from too much dirt on the skin or in the pores. Too much scrubbing may actually make acne worse.
  2. Acne is not caused by eating "fast" foods, chocolate or high-fat foods.

Symptoms

Acne appears on the skin as:

 

• congested pores ("comedones"), also known as blackheads or whiteheads,

• tender red bumps also known as pimples or zits,

• pustules,

• cysts (deep pimples, boils).

 

What other skin conditions can mimic acne?

 

Rosacea:

This condition is characterized by pimples but not comedones and occurs in the middle third of the face, along with redness, flushing, and superficial blood vessels. It generally affects people in their 30s and 40s and older.

 

Pseudofolliculitis:

This is sometimes called "razor bumps" or "razor rash". When cut close to the skin, curly neck hairs bend under the skin and produce pimples. This is a mechanical problem, and treatment involves shaving less (growing a beard, laser hair removal). Pseudofolliculitis can, of course, occur in patients who have acne, too.

 

Folliculitis:

Pimples can occur on other parts of the body, such as the abdomen, buttocks, or legs. These represent not acne but inflamed follicles. If these don't go away on their own, doctors can prescribe oral or external antibiotics, generally not the same ones used for acne.

 

Gram-negative folliculitis:

Some patients who have been treated with oral antibiotics for long periods develop pustules filled with bacteria resistant to the antibiotics which have previously been used. Bacterial culture tests can identify these germs, leading the doctor to prescribe different antibiotics or other forms of treatment.

Causes

No one factor causes acne. Acne happens when sebaceous (oil) glands attached to the hair follicles are stimulated at the time of puberty by elevated levels of male hormones. Sebum (oil) is a natural substance which lubricates and protects the skin. Associated with increased oil production is a change in the manner in which the skin cells mature so that they are predisposed to clog the follicular openings or pores.

 

The clogged hair follicle gradually enlarges, producing a bump. As the follicle enlarges, the wall may rupture, allowing irritating substances and normal skin bacteria access into the deeper layers of the skin, ultimately producing inflammation.

 

Inflammation near the skin's surface produces a pustule; deeper inflammation results in a papule (pimple); deeper still and it's a cyst. If the oil breaks though to the surface, the result is a "whitehead". If the oil accumulates melanin pigment or becomes oxidized, the oil changes from white to black, and the result is a "blackhead." Blackheads are therefore not dirt and do not reflect poor hygiene.

 

Here are some factors that don't usually play a role in acne:

 

Heredity: With the exception of very severe acne, most people do not have the problem exactly as their parents did. Almost everyone has some acne at some point in their life.

 

Food: Parents often tell teens to avoid pizza, chocolate, greasy and fried foods, and junk food. While these foods may not be good for overall health, they don't cause acne or make it worse. Although some recent studies have implicated milk and pure chocolate in aggravating acne, these findings are very far from established.

 

Dirt: As mentioned above, "blackheads" are oxidized oil, not dirt. Sweat does not cause acne, therefore, it is not necessary to shower instantly after exercise for fear that sweat will clog pores. On the other hand, excessive washing can dry and irritate the skin.

 

Stress: Some people get so upset by their pimples that they pick at them and make them last longer. Stress, however, does not play much of a direct role in causing acne.

 

In occasional patients, the following may be contributing factors:

 

Pressure:

In some patients, pressure from helmets, chin straps, collars, suspenders, and the like can aggravate acne.

 

Drugs:

Some medications may cause or worsen acne, such as those containing iodides, bromides, or oral or injected steroids (either the medically prescribed prednisone [Deltasone, Orasone, Prednicen-M, Liquid Pred] or the steroids that bodybuilders or athletes take). Other drugs that can cause or aggravate acne are anticonvulsant medications and lithium (Eskalith, Lithobid), which is used to treat bipolar disorder. Most cases of acne, however, are not drug related.

 

Occupations:

In some jobs, exposure to industrial products like cutting oils may produce acne.

 

Cosmetics:

Some cosmetics and skin-care products are pore clogging ("comedogenic"). Of the many available brands of skin-care products, it is important to read the list of ingredients and choose those which have water listed first or second if you are concerned about acne. These "water-based" products are usually safe.

Treatment

Since everyone gets acne at some time, the right time to treat it is when it bothers you or when the potential for scarring develops. This can be when severe acne flares suddenly, for mild acne that just won't go away, or even when a single pimple decides to show up the week before your prom or wedding. The decision is yours.

 

Think back to the three basic causes of acne and you can understand why the focus of both home treatment and prescription therapy is to unclog pores, kill bacteria, and minimize oil.

 

But first a word about ...

 

Lifestyle:

Moderation and regularity are good things, but not everyone can sleep eight hours, eat three good meals, and drink eight glasses of water a day. You can, however, still control your acne even if your routine is frantic and unpredictable. Probably the most useful lifestyle changes you can make are to never to pick or squeeze pimples. Playing with or popping pimples, no matter how careful and clean you are, nearly always makes bumps stay redder and bumpier longer. People often refer to redness as "scarring", but fortunately it usually isn't in the permanent sense. It's just a mark that takes months to fade if left entirely alone.

 

Open the pores!

Cleansing and skin care: Despite what you read in popular style and fashion magazines, there is no magic product or regimen that is right for every person and situation.

 

Mild cleansers:

Washing once or twice a day with a mild cleansing bar or liquid (for example, Dove, Neutrogena, Basis, Purpose, and Cetaphil are all inexpensive and popular) will keep the skin clean and minimize sensitivity and irritation.

 

Exfoliating cleansers and masques:

A variety of mild scrubs, exfoliants, and masks can be used. These products contain either fine granules or salicylic acid in a concentration that makes it a very mild peeling agent. These products remove the outer layer of the skin and thus open pores. Products containing glycolic or alpha hydroxy acids are also gentle skin exfoliants.

 

Retinol:

Not to be confused with the prescription medication Retin-A, this derivative of vitamin A can help promote skin peeling.

 

Kill the bacteria!

 

Antibacterial cleansers:

The most popular ingredient in over-the-counter antibacterial cleansers is benzoyl peroxide.

 

Topical (external) applications:

These products come in the form of gels, creams, and lotions, which are applied to the affected area. The active ingredients that kill surface bacteria include benzoyl peroxide, sulfur, and resorcinol. Some brands promoted on the Internet and cable TV (such as ProActiv) are much more costly than identical products you can buy in the drugstore.

 

Benzoyl peroxide causes red and scaly skin irritation in a small number of people, which goes away as soon as you stop using the product. Keep in mind that benzoyl peroxide is a bleach, so do not let products containing benzoyl peroxide leave unsightly blotching on colored clothes, shirts, towels, and carpets.

 

Reduce the oil!

You cannot stop your oil glands from producing oil (unless you mess with your hormones or metabolism in ways you shouldn't). Even isotretinoin only slows down oil glands for a while; they come back to life later. What you can do is to get rid of oil on the surface of the skin and reduce the embarrassing shine.

 

Use a gentle astringent/toner to wipe away oil. (There are many brands available in pharmacies, as well as from manufacturers of cosmetic lines.)

 

Products containing glycolic acid or one of the other alpha hydroxy acids are also mildly helpful in clearing the skin by causing the superficial layer of the skin to peel (exfoliate).

 

Masks containing sulfur and other ingredients draw out facial oil.

 

Antibacterial pads containing benzoyl peroxide have the additional benefit of helping you wipe away oil.
