Rosacea is a chronic disorder that mainly affects the skin of the central face. The most common and best-known symptom is persistent redness or flushing on the cheeks, nose, forehead, and/or chin. As the condition progresses, the redness lasts longer and becomes more noticeable. Small blood vessels may also appear on the patient’s skin. Rosacea typically develops in people who are over 30 years old. While it is more common in women, men tend to develop more severe symptoms.
What Causes Rosacea?
While researchers have not yet determined a cause, they are investigating several hypotheses that include the following:
• Microbes and Demodex mites
• Autoimmune disorder
• Changes in facial blood vessels
• Changes in the neurovascular system
There is evidence that rosacea can run in families. Similarly, it is more common in certain ethnic groups. Some geneticists have identified genetic components in rosacea. Other researchers, however, believe that it is only partly caused by genetics and that environmental factors also contribute.
What are Triggers?
Triggers are environmental factors that can cause a rosacea flare-up or make it worse. According to a survey conducted by the National Rosacea Society, the most common triggers are:
• Exposure to the sun
• Hot weather
• Strenuous exercise
• Alcohol consumption
• Hot baths
• Cold weather
Researchers hypothesize that these triggers demonstrate involvement of the sensory nervous system. They speculate that the triggers stimulate some of the sensory nerves around blood vessels, which may cause the inflammation and flushing.
