Generalized flushing often accompanies the papules, pustules, telangiectasia, coarse skin, and hyperplasia that are characteristic of this condition. These episodes of pimply red rash may be transient, but chronic hypertrophy of the sebaceous glands, called phyma, can produce persistent sometimes irreversible skin changes, such as a bulbous nose in rhinophymatous rosacea. Burning, stinging, and facial edema often accompany active lesions. Vision impairment can occur in those with ocular involvement, but serious complications are uncommon. Rather, the disease burden derives largely from psychosocial consequences of facial lesions, which have been associated with negative effects on quality of life due to depression and anxiety.  The variable estimated prevalence of rosacea, which typically first develops in individuals between 30 and 50 years of age, ranges from 2% to 22% in predominantly fair-skinned populations. It is more common in women than in men. It has been estimated that more than three million Canadians have rosacea when extrapolated from an expected prevalence rate of 10%. The underlying causes of rosacea are unclear, but many patients associate the onset of flares with triggers such as stress, spicy food, hot beverages, ultraviolet light, and alcohol. Avoidance of triggers is a foundation of intervention. Although a long list of medications offer potential benefit based on empiric reports of efficacy, controlled trials with pharmacologic agents remain limited."}
