While the cause of rosacea is not known, some risk factors (characteristics that identify a person as more likely to develop rosacea) have been identified. One of the risk factors of rosacea is skin type. People with fair or light-colored skin, blonde or red hair and blue or green eyes are more susceptible to rosacea. Also, rosacea also has a "hereditary" component, which simply means that rosacea tends to run in families.
Certain environmental factors, known as "triggers", can cause flare-ups and worsening of rosacea symptoms.
Triggers can be found everywhere. Certain foods, beverages, cosmetics, changes in temperature and humidity, wind, emotional stress - these are just some of the things that may trigger a rosacea flare-up. What's more, triggers vary from one person to the next. One person may need to avoid chocolate entirely or risk a bad flare-up, while another can eat chocolate but not cheese. Still another person may enjoy both, but start flushing after a few sips of hot coffee.
While medication is an essential part of symptom management for most rosacea patients, learning to identify and avoid triggers is also important. You can find out more about triggers by visiting the Food & Drink, Lifestyle and Tracking pages of this website.
