Rosacea is a chronic skin condition in which the facial skin appears red. Small red bumps filled with what looks like pus may accompany the skin redness. For this reason, rosacea is sometimes referred to as "adult acne." However, acne and rosacea are 2 separate skin conditions.
Rosacea usually begins in middle age, but it can also affect young adults. People from 30 to 60 years old are most commonly affected. Although women are more often diagnosed with the condition, men are more likely to show severe symptoms. Rosacea is more common in individuals with fair skin.
Without treatment, rosacea can get worse over time. However, early diagnosis and treatment can help prevent this from happening. Rosacea does not endanger a person's physical health, but unfortunately it is a chronic (ongoing) condition and there is currently no known cure for it.
It is not known what causes rosacea. While genetics likely play a role, alcohol is not a cause. Drinking alcohol may simply cause flushing of the skin in people who already have the condition.
Scientists also point towards other potential factors that may include skin mites, gastrointestinal infection, a blood vessel disorder, and sun damage of the skin. These and other theories are still under investigation.
