Rosacea is a chronic skin condition characterized primarily by facial redness and often accompanied by other symptoms like visible blood vessels, swollen red bumps, and skin sensitivity. It typically affects the central part of the face, especially the nose, cheeks, forehead, and chin.

The exact cause of rosacea is unknown, but it may be related to genetic factors, environmental triggers, and vascular and inflammatory issues. Common triggers that can exacerbate rosacea include sun exposure, hot or spicy foods, alcohol, stress, and extreme temperatures. While rosacea is more common in middle-aged women with fair skin, it can affect individuals of any skin type and age. The condition can have a significant psychosocial impact, often leading to decreased self-esteem and social anxiety due to its visible and sometimes unpredictable flare-ups.
