Why do people have acne

What is acne

The sebum glands usually keep skin and hair shiny and supple. If they produce too much sebum, what is known as seborrhea develops. If the exits of the sebum glands are blocked with a horn plug, you will get pimples and your skin will be greasy. The pimples occur mainly on the face, shoulders and back as well as on the chest, because there are a particularly large number of sebum glands in these parts of the body.

So-called propioni bacteria increasingly accumulate in the sebum. These bacteria are always found on the skin. If they multiply strongly and can no longer be transported away by the closed sebum gland, the affected skin areas become inflamed.

Acne can manifest itself in various forms, which differ in severity and degree of inflammation. If your acne heals, scars may appear. The severity of these scars depends on the severity of the acne and various factors in the immune system. It differs from person to person.

With an optimally coordinated treatment, you can get through puberty - or any other pimple phase in your life.


With the TK doctor guide you will find the dermatologist (dermatologist) you trust, who will help you with all questions about your acne.

Why you?

The main cause of pimples in adolescents are often so-called androgens, i.e. sex hormones such as testosterone. During puberty, hormone levels change. If your body produces a lot of testosterone, this promotes the development of acne. Girls and women have less testosterone, so acne affects them less often. Statistically, almost all teenagers through puberty have acne, which means they get pimples. Moderate or severe courses are rare and affect an average of 15 to 30 percent of adolescents.

During puberty you suspect: your parents are to blame for everything! This also applies to acne to a certain extent, because the predisposition to acne can be inherited. The chances of developing acne are higher if your parents also had acne.

Hormones in cortisone-containing drugs, for example, can also cause acne. Anabolic steroids for building muscle also contain hormones that can lead to acne. If you have irritated skin or cannot tolerate certain ingredients in skin care products, this can also promote acne. Oily or excessive skin care treatments can also promote reactions such as acne.

Adults are also affected

Adolescents are more likely to have acne than any other age group. By the age of 25 at the latest, your hormonal balance has usually stabilized and the acne disappears. Sometimes, however, it persists, in which case doctors speak of what is known as persistent acne.

Adults, especially women, can develop new acne disorders. Stressful situations or hormonal fluctuations, for example due to the period, can trigger what is known as acne tarda or late acne. Often unsuitable and frequently used care products trigger late-onset acne.

Myth or Truth?

Only teenagers get acne.

This is wrong. Adults can also develop acne, known as acne tarda or late acne. This type of acne is common in people over the age of 25.

Poor personal hygiene leads to acne.

This prejudice persists. But acne occurs when the sebum glands become blocked. This causes bacteria to accumulate in the sebum gland, which can cause inflammation and accumulation of pus.

If you eat healthy, you won't get acne.

A diet high in carbohydrates and dairy products can promote acne. For example, those who regularly use protein shakes may promote so-called bodybuilding or gym acne. If you suspect that you may react with pimples to certain foods, it helps to keep a food diary from time to time. You can then discuss the results with your doctor. You can find a lot of information about nutrition and recipe tips in the TK youth portal pointer.de.

A black point in the pimple is trapped dirt.

That's not true. Melanin, the pigment in your skin, turns the surface of the blackhead blackish when it comes into contact with air. If the blackheads have not yet come into contact with air, they are white.

The more you care for your skin, the milder your acne will be.

On the contrary: too much care can lead to additional skin irritation, which can even worsen your acne. Less is often more now. You can do your skin a lot of good with clear water and mild care products, which you should use sparingly.
