What causes rosacea?
Experts still don’t know exactly what causes rosacea, but there are a few factors that could be to blame.
Demodex folliculorum is a microscopic mite that lives on our skin. While everyone has the mite, experts found that people affected by rosacea have higher levels of them. This being said, they still don’t know if this is a cause or a result of the condition.
Blood vessel abnormalities may lead to facial flushing and redness, which is a common trait of people suffering from rosacea. While we don’t know what causes this abnormality, it’s thought that sun damage may play a contributing factor. Some think that it causes a dilation of skin vessels, resulting in thread veins, redness and inflammation.
Finally, we know that rosacea seems to be hereditary, with multiple family members suffering from the condition. However, experts have still not identified the specific genes that cause rosacea and research continues.
