Medical Description
Rosacea, or acne rosacea is a chronic, progressive disorder of the skin manifested by small red spots (papules) and persistent facial redness (rosacea). Her cheeks and nose are the first to take on a purplish tint, followed by the forehead and chin.
Rosacea can affect any person aged 20 to 70 years, but adults 30 to 50 years old with fair complexion and whose skin has a tendency to blush easily are most often affected. Approximately 10% of the population would be affected by rosacea, to varying degrees. Women are more prone than men, but they are more likely to be affected by rhinophyma. This disorder is characterized by a red nose, swollen and bumpy. It is secondary to untreated rosacea.
Though referred to as acne rosacea, rosacea has actually very little in common with acne, which occurs in adolescents. The black dots and white buttons are virtually absent.
Causes of Rosacea
The causes are unknown. Various theories suggest that rosacea is caused by bacteria, mites, fungi, malfunction of the connective tissue under the skin or psychological factors, but none of them has been proven. The sensitivity of some individuals is attributed to various factors such as heredity and skin tone.
What factors may aggravate the rosacea is known that various causes tend to aggravate rosacea or to cause outbreaks in some people, particularly factors that cause an increase in internal temperature of the body.
