Before the advent of modern medicine, it was commonly believed that rosacea was a side effect of excessive drinking. Today, of course, we know that rosacea is not a symptom of alcoholism, nor is there any reason to think that people with rosacea necessarily drink more than the average adult — in fact, even a teetotaler may have the condition. 

While some people may enjoy a drink or two as a way to lift their spirits or relax and unwind, many rosacea patients find that alcohol simply adds to their stress level by causing an outbreak of signs and symptoms.
