The cause of rosacea is unknown, but researchers believe it's likely due to some combination of hereditary and environmental factors.
A number of factors can aggravate rosacea or make it worse 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, saunas
- Drugs that dilate blood vessels, including some blood pressure medications
One thing is certain — alcohol doesn't cause rosacea. Although drinking alcohol can lead to flushing of the skin and may worsen rosacea, people who don't drink alcohol can get rosacea.
