Acne: what are the reasons?

Home

Black points, white points. To adolescence, the acne prevents to see life in rose well often. But what the reasons of this skin illness are that affects close to 80% of the young at the hour of the first agitations in love? Passage in magazine of the three main guilty parties.

The acne is an illness affecting the pilous follicle, to the root of our hairs. To his basis the sebaceous glands are responsible for the production of sébum, fat matter preventing the drying up of skin. But at the time of the puberty, this well lubricated mechanism stopped himself!

The acne in three stages

The apparition of a button to the level of the follicle is due to the conjunction of three stages:

Excessive secretion of sebum in the follicle;
Obstruction of the follicle (for an even unknown reason);
Bacterial development inside the follicle.

At the time of the puberty, the production of masculine sexual hormones (androgens) drags an excess of sebum to the level of the sebaceous glands. The sebum in excess flows out to the surface of skin that becomes then fatter. But the channel can clutter itself and the pore plugs itself, it is the apparition of the black point or comedo or of a white microkyste.

Thereafter, the development of an inflammation inside the follicles and the infection of these by a bacterium, Propionibacterium acnes, entail some buttons (papules, pocks and nodules).

Stress and heredity

Stress is accused of all pains, so one sometimes accuses it of being responsible for the apparition of the acne. One knows otherwise that stress can have an influence on the hormonal concentrations. He could have an influence therefore on the development of this cutaneous illness. But according to the last magazine in date, his role remained on this day the object of controversy and one lacks scientific studies validated on the topic curiously.

Otherwise, numerous studies note a number important of patients of the two sexes in a same family. Although a genetic touchiness has can be suspected, no scientific proof has cannot be made on this day.
