Rosacea is a persistent skin condition identified by facial redness, noticeable blood vessels, and, occasionally, acne-like bumps. It typically affects the central areas of the face, such as the cheeks, nose, and forehead. While the exact cause of rosacea remains unclear, factors like genetics, abnormal blood vessel function, and an overactive immune system response are believed to contribute to its development. Triggers such as sun exposure, spicy foods, alcohol, and certain skincare products can exacerbate the condition, leading to flare-ups of symptoms.
