What is a common characteristic of rosacea?

Rosacea is a chronic skin condition characterized by significant vascular changes, which often manifest as flushing and visible blood vessels on the skin. This condition typically affects the central part of the face, including the cheeks, nose, and forehead. The flushing is often triggered by factors such as heat, stress, and certain foods or beverages. Visible blood vessels, also known as telangiectasia, can become prominent due to the underlying inflammatory processes associated with rosacea. These characteristics distinguish it from other skin conditions that exhibit different symptoms, such as silvery patches seen in psoriasis or patchy skin discoloration related to conditions like vitiligo. Understanding the defining features of rosacea helps in proper diagnosis and management.
