The cause of rosacea is unknown, but it could be due to some combination of hereditary and environmental factors.
A number of factors can trigger or aggravate rosacea by increasing blood flow to the surface of your skin. Some of these factors include:
- Hot foods or beverages
- Spicy foods
- Temperature extremes
- Stress, anger or embarrassment
- Strenuous exercise
- Hot baths or saunas
- Corticosteroids, such as prednisone
- Drugs that dilate blood vessels, including some blood pressure medications
