Causes of Rosacea?

- It runs in families. Many people who get rosacea have family members who have it too. People may inherit genes for this specific skin condition.
- The immune system may play a role. Scientists found that most people with acne-like rosacea react to a bacterium (singular for bacteria) called bacillus oleronius. This reaction causes their immune system to overreact. Scientists still do not know whether this can cause rosacea.
- A bug that causes infections in the intestines may play a role. This bug, H pylori, is common in people who have rosacea. Scientists cannot prove that H pylori can cause redness. Many people who do not have this skin condition have an H pylori infection.
- A mite that lives on everyone’s skin, Demodex, may play a role. This mite likes to live on the nose and cheeks, where the redness often appears. Many studies found that people with rosacea have large numbers of this mite on their skin. But there are people with this mite on their skin who do not experience any redness.
- A protein that normally protects the skin from infection, cathelicidin, may cause redness and swelling. How the body processes this protein may determine whether a person gets rosacea.
