Acne gives the combination of symptoms like greasy skin, white heads, black heads, pimples, inflammation and scar formation. Acne mostly affects young people in the age 14 – 25, but also sometimes older persons, like women in their menopause. Most teenagers experience outburst of acne, some only little, but for others acne may develop into a serious skin ailment with great cosmetic impact.

THE SKIN ANATOMY

To understand the acne process, some knowledge about skin anatomy and physiology is essential:

The skin has there layers: The outer layer called epidermis consists of epithelial cells. Under this lies the dermis consisting of connective tissue. At the bottom there is a layer called the hypodermis consisting mostly of fat cells.

The skin has narrow pores extending from the surface down to the top of the sub-dermis, called hair follicles. A hair extend from a growth zone in the bottom of each hair follicle and out at the skin surface. Around the hair in the dermis, there are small glands called sebaceous glands. These glands produce a fatty substance, sebum, which empty through the follicle opening and lubricates the hair and the skin.

THE ACNE PROCESS

Acne starts by the glands in the hair follicles increasing their sebum production. This will in the beginning only cause greasy skin. Eventually the sebum in the entrance of the follicles mixes with dead epithelial cells. This mix reacts chemically to forms hard props, comedones that close the pore entrances. According to the color of the comedones, they are called black heads or white heads.

Then the closed hair follicle gets filled with sebum and swell. The swollen follicle then gets infected by bacteria. The bacteria and the accumulated sebum cause the follicle and the surrounding skin to get inflamed, forming a pimple. At last the inflamed follicle burst and empties its content. Eventually the affected area heals. Sometimes the inflammation reaches deep into the skin surrounding the follicle and destroys skin tissue. This will cause more or less distinct scars that may reside permanently. Typically an affected person will have follicles in all these stages of the process at any given time.

THE CAUSES OF ACNE

The increased hormone production in the puberty stimulates to increased sebum production. The male hormone, testosterone, seem to contribute most. Also girls begin to produce more testosterone in the puberty. Also in other periods, altered hormone production may give acne, for example by women in the menopause.

Since not all teens get acne in any degree, the increased hormone level cannot be the whole cause of the increased sebum production. The follicles of affected persons must for some reason react stronger upon the higher hormone level.

Dietary factors, like eating too much fat, too much sugar or the wrong kind of fat may aggravate acne by some individuals. Lack of vitamins, minerals and essential fatty acids may also contribute to development of acne.

Poor digestion, lazy colon and constipation aggravate acne in some individuals, probably due to productions of toxins in the intestines. Lazy colon may be caused by dietary faults, like lack of fiber.

Very frequent washing and use of strong soaps aggravate acne, and does not alleviate the condition as many think. Rubbing, scrubbing or squeezing the skin may also aggravate acne.

Here are some other factors that may contribute in causing acne or aggravating the condition.

- Stress
- Some contraceptive agents
- Environmental or domestic pollution.
- Humid environments.
- Some antidepressants.
- Testosterone and anabolic steroids used for treatment or by body-building.
- Use of some types of greasy cosmetic products.
- Some antiperspirant products.
- Exposing the skin for chlorine or other halogens, or medicines containing halogens.
- Women may get aggravated acne 2-7 days before menstruation.

WHAT CAN YOU DO YOURSELF TO AVOID OR TO TREAT ACNE

Sometimes Acne is so severe that special medical treatment is required, and sometimes the causes of acne necessitate medical treatment. But you can do much yourself also. Here are listed things you can do yourself to prevent or treat acne:

1. Some advices about diet that may help prevent and cure acne:

- Do not consume a great amount of fat.
- The fat you add to the food should be natural oils. Olive oil is ideal, but use other types of oils too, like walnut oil, sunflower oil and soy oil. However, do not use only soy oil as many tend to do. Using only soy oil will give you too much of some fatty acids and too less of others.
- Eat much fish, seafood and not so much meat.
- Eat food with a high fiber content to regulate the digestion, like vegetables, whole cereals, full corn bread and fruit.

2. Here are some things you should avoid.

- If you perform body-building, do not use anabolic steroids or other hormonal supplements.
- Use clothes that allow air to reach your body surface to avoid collection of humidity and overheating of your skin.

3. Use of rinsing milk or solutions

You can rinse your skin with mild products especially made to dissolve the plugs in your pores, and to make the environment in your skin unfriendly to bacteria causing infection. Some of these products are just products to wash your skin with one ore more times a day; others should be on during night and flushed away in the morning.

Tea tree oil and Grapefruit seed extract are natural antibacterial agents used in many of these products. In other products artificial compounds like Benzoyl peroxide are used.

Whenever body suffers any injury, the body rushes its soldiers to protect itself. Acne infection is also an injury that needs repair and body sends white blood cells and other molecules that fight the infection and repair the infected site. After the repairing job is completed, a scar forms that is the sign of repair. Skin never becomes as smooth as it was before the acne. Some scar is always left. Let us find out more about acne scars and how doctors can repair them so that you get something similar to your earlier look again.

Types Of acne scars- before we discuss about the type of scars, let us also note that everyone has different tendency of scar formation. Some people develop very less scars, while others may have major scars for the same type of acne. Acne scars are of two types- scars that are caused by loss of tissue and scars caused by increased tissue formation.

Depressed Scars- these scars may be of different types such as Ice-pick scars, depressed fibrotic scars, soft scars and macular types. As the cyst expands with pus, bacteria, oil and dead skin cells it ruptures and attacks the dermis. to protect the dermis the white blood cells rush in. This rupture may cause loss of collagen giving rise to deep recess or depression. The skin above is left unsupported because of loss of tissue below it and a saucer shaped or jagged ice pick scar is formed. Ice pick scars are more common on face.

Keloids- In some people the scar forms in a reverse fashion. With the loss of collagen, body triggers fibroblasts that produce excessive collagen producing scar tissues called keloids. Keloids are more commonly found on male torsos. Other type of increased tissue formation scar is called hypertrophic scar. Hypertrophy means overgrowth.

Scar Treatment- scars can be treated by your dermatologist using different treatments. Before proceeding for scar treatment, you have to discuss your feelings about the scars with your doctor. The cost involved may also play a role in choosing the treatment. What results you desire is the third factor. The severity of the scar, the location and type of treatments that can be done are other factors that have to be used to treat acne scars. The common treatments for acne scars are- collagen treatment, laser treatment, dremabrasion, microdermabrasion, skin surgery, skin grafting etc. Keloids may be left untreated if it is felt that treatment will form further keloids. Injecting with steroid injections may also treat keloids.
