Rosacea Causes

        One of the biggest mysteries surrounding rosacea must be its actual causes. Now, nobody is saying that some of the rosacea causes are not suspected, but none of them have actually been proven clinically or have been accepted widely by the medical community.

        Some people believe that one of the most important rosacea causes is genetic, while others think that it goes far beyond the genes of ones' parents and straight into the shared gene pool of certain populations. For example, clear and very pale skin is almost a guarantee that that particular person will suffer from rosacea sometime in his or her life. Usually, the English and the Irish are well known for their rosacea caused skin problems.

        Other researchers believe that the genes are only one part of the mystery and that the list of rosacea causes should include overexposure to sun, a mite found in hair follicles, called Demodex folliculorum, the bacteria Heliobacter pilori, known for being the main reason behind the appearance of bacterial ulcer and medication that causes the blood vessels to expand. Basically, the physiological cause of rosacea is the dilation of the small blood vessels that exist just below the skin of the face. When these expand in diameter, their walls tend to fissure and tiny streams of blood exit and settle right beneath the skin, creating the easy to spot aspect of rosacea skin.
