Couperose

One does not know the cause of couperose but one knows that, with certain people, various factors can aggravate or favourise the triggers :

Prolonged exposure to the sun or bronzing lamps.
The UVA rays favourise the dilation of the blood vessels which, after a certain time, can become permanent. The heat exerted also has a harmful effect. In dilating the vessels, the effect of the rays is accentuated.

Sudden change in temperature.
Exposure to extreme climate conditions.

Radiotherapy.
In increasing the body temperature, it favourises the dilation of the blood vessels.

Hereditary.
Certain surgeries, for example rhinoplasty.
The number of sessions depends on the state of the vessels, generally about 1 to 3 sessions.
