Rosacea is a chronic disease which usually first appears as subtle reddening on the face. It is usually focused on the center of the face. Rosacea commonly starts on the nose and spread outwards to include the cheeks, chin and forehead. Over time this may develop into some inflammation and may be accompanied by skin eruptions. If left untreated, rosacea can worsen over time and even affect the eyelids and mucous membranes. This version is the first release on CNET Download.com.
