Acne: which are the causes?
Black spots, white points… With adolescence, the acne very often prevents from seeing the bed of roses. But which are the causes of this skin disease which assigns nearly 80% of the young people to the hour of the first agitations in love? Passage in review of the three principal culprits.

The acne is a disease affecting the pilous follicule, with the root of our hairs. With its base the sébacées glands responsible for the production of sebum are, fat contents preventing the drying of the skin. But at the time of puberty, this well oiled mechanism is stopped!

Acne in three stages
The appearance of a button on the level of the follicule is due to the conjunction of three events:

Excessive secretion of sebum in the follicule;
Obstruction of the follicule (for a still unknown reason);
Bacterial development inside the follicule.
At the time of puberty, the production of male sex hormones (androgens) involves an excess of sebum on the level of sébacées glands. The sebum in excess runs out on the surface of the skin which becomes fattier then. But the channel can be encumbered and the pore is stopped, it is the appearance of the black spot or comedo or a white microkyste. 

Cut skin 

Thereafter, the development of one ignition inside the follicules and the infection of those by a bacterium, Propionibacterium acnes, involves buttons (papules, pustules and nodules).

Stress and heredity

The stress is shown of all the evils, thus one sometimes shows it to be responsible for the appearance of the acne. It is known in addition that the stress can have an influence on the hormonal concentrations. It could thus have an influence on the development of this cutaneous disease. But according to the last review in date, its role to date remains the object of controversy and one singularly misses scientific studies validated on the subject.

In addition, of many études2 note a big number of patients of the two sexes in the same family. Although a genetic susceptibility could be suspectée, no scientific proof could be made to date.
