The exact cause of rosacea isn’t clear, but medical professionals recognize a number of contributing factors, including:
- Heredity
- Environmental conditions
- Immune system issues
- Nervous system problems
- Vascular system problems
Additionally, a number of triggers may worsen symptoms or act as triggers that increase blood flow to the surface of your skin, making rosacea flare. These triggers are different for everyone, but often include:
- Spicy foods
- Alcohol
- Hot beverages
- Sun and wind
- Extreme temperatures of hot and cold
- Emotions
- Physical activity
- Cosmetics
- Certain medications
And, if you’re a woman with fair skin, or you’re over 30 and a smoker, you increase your risk for developing rosacea, especially if it runs in your family.
