The exact causes of the occurrence of rosacea remain, even today, unknown. Certain risk factors can promote the development of the disease, without being the cause.
Rosacea particularly affects women with skin and light eyes between 30 and 60 years - the peak frequency is around 45 years. In Sweden, where there are many fair skins, the prevalence of this condition is 10%. In France, it is less than 6%.
UVs play an important role in triggering disease or outbreaks. Photo-protection is therefore essential: little sun and sunscreen imperative! All screens are valid if you choose a high index (minimum 20). If your skin is very sensitive, prefer screens based on zinc oxide or titanium dioxide. Some day creams and foundations also include sun protection.
Another cause: a prolonged local treatment with cream containing cortisone (corticosteroid), we speak of "steroidal" rosacea.
It should also limit drinks and atmospheres too hot, sudden changes in temperature, spices and alcohol since they promote flushes and redness.
As for stress, it may be necessary to learn how to manage it if you feel that it intervenes a lot in your illness.
