2. Disorder of the Blood Vessels
Something that makes rosacea somewhat frustrating, is the fact that experts aren’t quite sure what causes it. In fact, there are several different leading theories which include the likes of ‘skin mites’, allergies, and more.
One of these current theories is that the rosacea is caused by a disorder of the blood vessels. Blood vessels are of course the veins and arteries that carry blood around the body. As well as veins and arteries though, they also include the tiny little blood vessels called capillaries. These can be seen just beneath the surface of the skin, and especially where the skin is very pale and/or thin. This is partly why those who are older, or who have very pale skin are somewhat more likely to experience the issue.
Whether this is the cause in some cases, all cases, or none at all is uncertain. However, what we can be certain of, is that rosacea often appears alongside the appearance of tiny blood vessels around the face. If you have very small, blue, spider-web looking veins appearing on your skin, then this would suggest that there is at least some role for blood vessels to play.
And in this case, you might be well-served to address issues such as blood pressure.
