Problems with Your Immune System

When your immune system isn’t functioning well, it could lead to the development of rosacea by creating abnormal proteins. These proteins affect the way blood vessels work and can cause redness or swelling (inflammation). The human immune system protects your skin from microorganisms, damage from the UV rays and also physical or chemical injury. Problems with your immune system can lead to long-term redness or inflammation, as well as blood vessel dysfunction often seen in rosacea.

A Reaction to Microorganisms

Reactions to germs on the skin may be the cause of skin redness or swelling. There are a number of different germs or microorganisms that can cause this:

Demodex Mite and Bacillus Oleronius Demodex causes rosacea by way of a reaction to the proteins produced by bacillus oleronius, an allergic reaction to Demodex or other microbes that may be associated with Demodex mites.

Helicobacter pylori Most commonly known for its role in acid reflux (heartburn), this bacterial infection in rosacea is debatable.

Staphylococcus epidermidis, chlamydia pneumoniae, and small intestine bacteria.

Sun Exposure

Ultraviolet rays from the sun are often a trigger for rosacea. People with rosacea often also experience photosensitivity. Wearing full-spectrum sunscreen and clothing to cover up the skin will have immediate benefits.

Inappropriate Blood Vessel Function

Facial flushing is common in rosacea and it’s due to increased blood flow in the skin of some rosacea patients. This means overactive blood vessels could be a cause of rosacea. Overactive blood vessels are a potential link to abnormalities in the nerves that control them, including those regulating body temperature, which is why overheating can lead to flushing in rosacea patients.

Genetics

People with a family history of rosacea are more likely to develop the disorder. However, at this time genes related to an increased risk for rosacea have not been identified.
