Acne Rosacea Information
Rosacea is a chronic disorder involving the central face including the cheeks, chin, nose, and central forehead. There are various combinations of flushing, erythema, telangiectasia, edema, papules, pustules, ocular lesions, and deep inflammation of the nose.
These signs may be transient and each may occur independently. One or more of the features may be present. There are remissions and exacerbations. The etiology and pathogenesis are unknown and there are no histologic or serologic markers.
Rosacea is common with a prevalence as high as 10% in some populations. It appears to be more common in people with fair skin, but it is also found in Asians and African Americans. Rosacea may occur at any age but most patients are over 30.
Rosacea has been classified into 4 subtypes. Evolution from one subtype to another may occur. It is important to treat rosacea to prevent progression of disease.
