L71: Rosacea

Rosacea is a chronic skin condition characterized by facial redness, swelling, and small, red, pus-filled bumps. It predominantly affects the central areas of the face like the cheeks, chin, nose, and forehead. The exact cause of this condition is unknown, but it's thought to be a combination of hereditary and environmental factors. Different triggers can worsen rosacea, such as hot drinks, spicy foods, alcohol, temperature extremes, sunlight, stress, and certain medications. Although it's prevalent in individuals with fair skin, it can affect people of all skin types and typically begins after age 30. It’s not contagious or infectious, meaning it cannot be passed on by touching or through sharing personal items. Rosacea's progression varies from person to person, with some experiencing mild symptoms and others severe. It regularly cycles between periods of exacerbation and remission. The skin, and occasionally the eyes, are the body systems primarily affected by this condition.
