Rosacea is usually unavoidable in most people. However, certain trigger factors that may worsen the condition can be avoided. These include:
The main effect of rosacea is disfigurement due to scarring. This is particularly true in men, who are prone to develop thickened tissue on the nose. In serious cases, the eyes may be involved, and that may cause vision problems. The person may suffer emotionally from having a chronic skin disorder.
There are no risks to others, as this condition is not contagious.
