There is nothing called as Roseria. I think you are referring to Rosacea. Rosacea is a chronic skin disease (long term disease) that affects the skin and sometimes eyes. The disorder is characterized by frequent redness mostly at the center of the face (nose, cheeks, forehead and chin), maybe burning feeling and slight swelling, pimples, and, in advanced stages, thickened skin. Rosacea usually affects the face. In the US, about 14 million people have rosacea. Most commonly, women (especially during menopause), people with fair skin and adults between 30 to 60 years of age have rosacea.
The exact cause of rosacea is not known and it is an area for future research. Some doctors feel rosacea occurs when blood vessels expand easily and cause flushing. It is thought that it may be inherited and those who blush a lot may be more likely to get rosacea. One or more of these factors may worsen rosacea, though it requires further research.
