what is rosacea

Rosacea is a common and chronic skin condition that causes redness and visible blood vessels in your face. It may also produce small, red, pus-filled bumps. The condition can vary from mild to severe and typically affects the nose, cheeks, and forehead. Rosacea can be mistaken for acne or other skin problems, and its symptoms may flare for weeks to months and then go away for a while. The exact cause of rosacea is unknown, but it is believed to be a combination of genetic and environmental factors. Triggers for flare-ups may include sun or wind exposure, hot drinks, spicy foods, alcohol, emotional stress, and exercise
