Rosacea is diagnosed among adults – mainly among women over the age of 40. Although erythema and other symptoms are more common among women, severe forms of sebaceous glands rhinophyma mainly affect men. In case of women, erythematous, papular and pustular lesions during the course of acne rosacea is often of hormonal origin.Hence, the increased incidence of rosacea among women is identified during pregnancy, menopause, as well as ovulation and menstruation. The peak of the disease incidence is observed between the age of 30-60. The first symptoms of the disease may appear before the age of 25, but the acne itself only after puberty. The risk of developing rosacea is increased by diagnosed seborrheic dermatitis and acute acne that a patient suffered from. The incidence of rosacea is estimated to occur among 1-10% of the population, and it is increased among people with I and II skin phototypes. Scandinavia and Ireland are areas of increased rosacea incidence.
