The exact cause of rosacea is unknown, but there are several possible factors that have been suggested. Some of the possible causes of rosacea on the face include:
-
Abnormalities in blood vessels: Some experts believe that abnormalities in the blood vessels of the face may be a major contributing factor for rosacea. This may explain symptoms of flushing, persistent redness, and visible blood vessels. Its not known what causes these abnormalities, but sun damage may be responsible for degeneration of the elastic tissue of the skin and the dilation of blood vessels.
-
Overactive immune system: Rosacea could be due to an overactive immune system, which causes the immune system to overreact to certain triggers.
-
Heredity: Rosacea often runs in families, suggesting that genetics may play a role in its development.
-
Environmental factors: Exposure to sunlight, hot or cold weather, hot drinks, alcohol, and caffeine are some of the environmental factors that may trigger or worsen rosacea.
-
Microscopic mites: A reaction to microscopic mites commonly found on the face may also contribute to the development of rosacea.
Its important to note that while these factors may contribute to the development of rosacea, they do not necessarily cause it. Additionally, some people may have different triggers that cause their rosacea to flare up.
