Detailed answer

You should wear sunscreen if you have rosacea. Sun exposure can trigger rosacea flare-ups and worsen the condition. Sunscreen helps protect your skin from harmful UV rays that can cause inflammation and redness. Look for a broad-spectrum sunscreen with an SPF of 30 or higher, specifically designed for sensitive skin, and choose a physical sunscreen containing ingredients like zinc oxide or titanium dioxide. Apply sunscreen generously and reapply every two hours or as needed, especially if you're outdoors for an extended period of time.
