Rosacea Causes  

Contrary to what is often believed, rosacea is not caused by either alcohol or unhealthy lifestyle, although they can aggravate the disease. Medically, the causes of rosacea are unknown, however there are assumptions. Rosacea can be attributed to : 

  • strong emotions 
  • prolonged exposure to sunlight  
  • malfunction of the connective tissue under the skin of the face  
  • Blood congestion (blood flow is impeded) in the front area accompanied by vascular dilation (abnormal increase in size of tiny blood vessels).  
  • Bacteria : acne rosacea might be resulted from helicobacter pylori. In this case, the disease is associated with inflammation of the lining of the stomach and a lack of development (atrophy) of the mucosa of the jejunum (part of the small intestine) or a lipase deficiency (an enzyme the body uses to break down fats in food so they can be absorbed in the intestine). 
  • Parasites : demotex folliculorum is a species of parasite of the form of worm that can be found on the surface of the skin, particularly in the sebaceous glands. The sebaceous glands are located in the epidermis, causing an oily secretion called sebum. In secreting sebum, they allow the skin to protect against external aggression and to keep certain elasticity. At the onset of rosacea, demotex folliculorum would grow excessively leading to development of papules and pustules. The causes that lead to the proliferation of demotex folliculorum are still ignored by scientists.
