As mentioned earlier, the actual factors that are responsible for rosacea are not known as yet and research into this matter is ongoing. There are however a number of theories about the elements that are believed to be responsible for this condition.

What elements are believed to be responsible for rosacea?

A very common belief is that rosacea may be caused by a microscopic pest known as Demodex Follicuralum, or the demodex mite. These pests live around the hair follicles and are mobile mainly during night time. Their invasion of the follicles in humans is known as demodicosis and is usually free from any symptoms, but may trigger reactions accompanied by rashes and skin irritation. Demodex mites may be found in abundance in the cheeks and the use of antibiotics does not reduce their numbers significantly. Many believe that the reactions that are triggered by demodex mites arise due to the blockage of the hair follicles, although their exact mode of contribution to this disorder remains unknown. Studies have found that the prevalence of demodex mites in people with rosacea is far higher than their prevalence in people who do not suffer from the disorder. Studies have also revealed that the successful removal of the mites results in a significant improvement in rosacea symptoms.


However, a significant number of experts believe that the mites play no part what so ever in the aggravation of rosacea. Such people argue that the removal of demodex mites from the hair follicles may not be directly linked to the improvement in one’s rosacea symptoms, and that the actual process of removing the mites may indirectly have some benefit.

Other factors that are believed to be responsible for triggering rosacea include:-

  • Increased exposure to the sun, resulting in damage
  • Other environmental factors such as humidity and wind
  • Gastro intestinal diseases or lesions in the hypothalamus
  • Increased levels of exercise
  • Mental stress
  • Certain cosmetic products
