Rosacea is a common skin condition characterized by a red facial rash, often affecting the cheeks, forehead, and nose. It can also cause bumps, pustules, and visible small blood vessels near the surface of the skin. In some cases, additional symptoms like a burning or painful sensation may develop.
The exact cause of rosacea is unknown, but it is thought to be associated with various environmental factors. Sun exposure, temperature fluctuations, alcohol, spicy foods, and certain medications can exacerbate symptoms. Other common triggers include stress, cosmetic products, and hormonal changes. Rosacea generally occurs in adults over 30 and is more common in women than men.
