Why do we get acne? There are three main reasons

Acne is more common in adolescents, so it is also called [acne], and the incidence rate can reach about 85%.

The incidence rate is so high that when we see people who claim to have never developed acne, we always feel itchy palms and wish to paste his bear face. Although acne is not a serious life-threatening illness in what, it affects his appearance, thus causing anxiety, depression and social maladjustment of patients and significantly affecting his quality of life.

Teenagers are just socially active people. Just think, you just talked and laughed with your new friends yesterday, and today you are about to meet for dinner again. When you get up early in the morning and see two huge acne acne growing on the tip of your nose, there is no place to hide it, how can you feel good?

Why on earth does acne happen to teenagers? Today we will briefly talk about the causes of acne.

Acne is a multi-etiological skin disease, mainly involving three aspects.

First, accomplice: acne bacillus

In the past, it was always believed that acne was caused by acne bacillus. Now, we have realized that acne bacillus is one of the normal flora on the skin surface, but is naturally oily.

If your sebaceous glands are well developed and produce a lot of oil, they will happily come to settle down and have children. Then, their metabolites can induce and aggravate local inflammation.

Therefore, acne bacilli, although not the [culprit], is also an [accomplice], and their arrogance should be extinguished during treatment.

Second, the culprit: abnormal hair follicle keratosis

Acne bacillus is an anaerobic bacterium. It can multiply in large quantities, or does it have to be blocked by hair follicles? So, is what blocking hair follicles? In addition to grease and bacteria, there are many cutin debris.

If there is no bacterial infection, only acne, combined with bacterial infection, inflammatory papules will form.

Abnormal keratinization of hair follicle mouth is the real culprit causing acne.

Three, behind-the-scenes driving force: sebum secretion is excessive

Will sebum secretion be excessive in what?

Some people say that they eat too much? Some people say that they don’t like to wash their faces? In fact, these are not the most important.

The secretion of sebaceous glands, Is directly affected by androgens. Both men and women, There is a certain amount of androgen in the body. After puberty, androgen soars rapidly so that the host can grow up. By the way, many chubby sebaceous glands also grow up, resulting in a large amount of sebum. The whole face is oily. Even if there is no acne bacillus infection, this lump of oil alone can form acne.

In addition, there is a special situation, that is, pregnant women are also easy to grow acne, because progesterone also has a certain role in promoting sebaceous gland secretion. Mothers-to-be are carrying a small youth, long acne is also possible. This is the role of progesterone, and the sex of the fetus is not necessarily related. It is as good as giving birth to boys and girls, so there is no need to guess any more.

IV. Summary

Now let’s sort out our thoughts.

Changes in hormone levels cause exuberant oil secretion;

Abnormal keratinization and desquamation of hair follicle orifice cause hair follicle blockage;

Oil and hair follicle blockage together constitute a good condition for acne bacillus to multiply in large quantities.

Both of the above three are related to puberty, which is why acne always occurs in puberty.
