Detailed answer

Rosacea flare-ups can be triggered by multiple factors. Sun exposure is a common trigger, as ultraviolet rays can dilate blood vessels, leading to increased redness and inflammation. Certain foods and drinks, such as spicy foods, hot beverages, alcohol, and caffeine, can also cause flare-ups. Temperature changes, such as extreme cold or hot weather, can aggravate rosacea symptoms. Stress and emotional factors have been identified as triggers, possibly due to the release of stress hormones affecting blood vessels. Additionally, using irritating skincare products or harsh ingredients, such as alcohol-based products or strong exfoliants, can further irritate the skin and trigger rosacea flare-ups. It is essential to identify and avoid these triggers to minimize rosacea symptoms and maintain overall skin health.
