Rosacea Causes: Understanding the Triggers and Risk Factors

The exact cause of rosacea is unknown, but contributing factors include:

• Genetics: Family history increases susceptibility.
• Immune system dysfunction: Inflammation may be immune-mediated.
• Blood vessel abnormalities: Dilated, visible facial vessels contribute to redness/flushing.
• Environmental triggers: Sunlight, extreme temperatures, certain chemicals/skincare products.
• Hormonal factors: More common in women; aggravated by pregnancy/menopause.

Rosacea is not contagious nor caused by poor hygiene. Understanding triggers helps manage symptoms.
