Rosacea is a chronic facial dermatosis characterized by non-transient erythema, and acute flares of papules and pustules, mainly on the convexities of the forehead, nose, cheeks and chin with concentration on the central face. Additional features of flushing and telangiectasia, oedema and rhinophyma and ocular symptoms are present in some patients. Rosacea affects both males and females in equal numbers, but male patients may develop more severe disease, and rhinophyma occurs almost exclusively in this sex. Peak onset is between 35 and 45 years. There may be accompanying seborrhoeic dermatitis and the orifices of the sebaceous glands especially around the nose, may be patulous in those prone to rhinophyma. The frequency of rosacea in populations vary from country to country and has not been accurately defined. Figures ranging from 0.09% to 10% of the population have been reported. It is uncommon in black-skinned individuals. About 15% of patients with rosacea give a positive family history of the disease.
