Unraveling the Mystery: What Causes Rosacea?
Published: May 17, 2024
Understanding what causes rosacea can help in managing and preventing flare-ups effectively.
The Immune System's Role
Abnormalities in the immune system can trigger inflammation, a key feature of rosacea. An overactive immune response can lead to the production of peptides that cause redness and swelling in the skin.
Microorganisms and Rosacea
Certain microorganisms, like Demodex mites and bacteria, can contribute to rosacea. These organisms are more prevalent in people with rosacea and may stimulate skin inflammation.
Environmental Triggers
Environmental factors such as sun exposure, hot beverages, and spicy foods can worsen rosacea. These triggers can cause blood vessels in the face to dilate, leading to redness.
