- It is believed that acne rosacea is caused by genetics and the environment, or a combination of both. People who have acne rosacea often have family members who have it as well. Also, excessive sun exposure and damage can lead to acne rosacea.
- Many foods and beverages can aggravate acne rosacea and raise the blood flow to the skin's surface. Spicy foods, alcohol and extremely hot foods or drinks (such as coffee) can all make acne rosacea worse and result in the skin flushing.
- Drugs that are capable of dilating the blood vessels (like some hypertension medicines) are also possible culprits of acne rosacea. Corticosteroids (drugs that are highly similar to cortisol, which is naturally produced within the adrenal gland) can also cause acne rosacea to appear.
- Certain people have a much higher likelihood of getting acne rosacea. These people include individuals with pale, light skin (especially with freckles), people who blush or flush frequently, and people between the ages of 30 and 60 (particularly women going through menopause).
- Other common causes of acne rosacea (for people who are prone) are saunas, hot showers or baths, vigorous physical activity, extremes in temperature (whether hot or cold), sunlight, being embarrassed or angry and emotional stress.
