Erythematotelangiectatic Rosacea (ETR) is one of the 4 sub-types of rosacea. It is a chronic relapsing skin condition. It causes: 

• Redness
• Discolouration
• Flushing

These frequent episodes happen mainly in the centre of the face – across the nose, cheeks and forehead. They can cause broken blood vessels, and swollen, dry and scaly skin. It often stings or burns.

When erythematotelangiectatic rosacea first develops, sufferers may notice episodes of symptoms that last several minutes at a time. Skin may also feel hot or painful and burning or stinging is common. You may notice extra sensitivity when the skin comes into contact with skincare products or water.

Erythematotelangiectatic Rosacea: Causes

Though the exact cause of ETR is unknown, potential causes include: 

Genetics

Many people with a subtype of rosacea have family members who also have a form of rosacea. 

Skin Mites

Rosacea sufferers tend to have a higher level of demodex on the skin than people without rosacea. Demodex are skin mites that live on the nose and cheeks. This suggests there is a possible link between the mites and rosacea symptoms. Demodex also carries “bacillus oleronious” bacteria.  Rosacea sufferers tend to have an overactive immune response to this bacteria. 

Gastrointestinal Infection

H. pylori bacteria infects the gastro-intestinal system. It is a common type of bacteria thar attacks the stomach lining. This infection is common in rosacea sufferers indicating another potential link.  Non-rosacea sufferers also get the infection so more research is necessary.

Cathelicidin Production

Cathelicidin is a protein that protects the skin from infection. Rosacea sufferers may process this protein differently to non-sufferers. This can cause redness, discolouration and swelling.

ETR: What To Do Next

Erythematotelangiectatic Rosacea can affect daily life. However, there are potential treatments that can help to ease symptoms. It is best to see a skincare professional to get advice on what the next steps should be. Laser therapy, such as SkinBase IPL, is often an effective erythematotelangiectatic rosacea treatment.
