Detailed answer

Sun exposure can worsen rosacea symptoms. The UV radiation from the sun is a common trigger for rosacea flare-ups. It can cause redness, flushing, and increased blood flow to the skin, leading to the development of more visible blood vessels. Sunburns can also exacerbate the inflammation and sensitivity associated with rosacea. Applying a broad-spectrum sunscreen with a high SPF and seeking shade during peak hours can help minimize sun-related flare-ups in individuals with rosacea.
