What causes rosacea?

The exact cause of rosacea is not fully understood, but it likely involves a combination of genetic, environmental, vascular, inflammatory, and microbial factors.

Several factors are known to trigger or exacerbate rosacea symptoms, including:

Genetics: There is evidence to suggest that rosacea may have a genetic component, as it often runs in families.

Abnormalities in Blood Vessels: Dysfunction in the blood vessels of the face may contribute to the redness and flushing associated with rosacea.

Immune System Response: Abnormal immune system responses, leading to inflammation in the skin, may play a role in rosacea development.

Demodex Mites: These microscopic mites that naturally inhabit human skin are found in higher numbers in individuals with rosacea. While their exact role in rosacea is still unclear, they may contribute to inflammation and irritation.

Triggers: Various factors can trigger or exacerbate rosacea symptoms, including:

Sun exposure
Hot or cold weather
Spicy foods
Alcohol consumption
Hot beverages
Emotional stress
Certain skincare products
Physical exertion
Medications that dilate blood vessels

Dysfunction of the Skin Barrier: Impairment in the skin's natural protective barrier may make individuals more susceptible to environmental triggers and inflammation.
