What Causes It?
The exact cause of rosacea is unknown, although, according to NRS, there are a number of theories about the root of the disease, which include:
● Facial blood vessels that dilate too easily, causing increased blood flow near the skin, which causes flushing
● Cathelicidins, or anti-microbial proteins that help the body fight off illness, may cause the inflammatory bumps and acne-like pimples, as well as the flushing associated with rosacea
● Triggers, which can range from UV light exposure to alcohol and spicy food, may trigger the sensory nervous system, causing redness and swelling.
● There may be a genetic component that causes rosacea. According to a study of twins conducted by Case Western University, researchers found that rosacea may occur more often in both identical twins than in sets of fraternal twins.
● Microscopic skin mites may play a role in triggering the acne-like bumps experienced by some rosacea patients
