Rosacea affects an estimated 14 million Americans. Adults, especially those between 30 and 50 years of age who have lighter skin, blonde hair and blue eyes, are most likely to suffer from rosacea. However, rosacea can affect children and people of any skin type. It is a chronic skin condition that causes redness of the face. Symptoms range from visible blood vessels (telangiectasias) with a tendency to flush easily to acne-like pimples.
