Rosacea is a chronic, inflammatory skin condition which principally affects the face. Rosacea worsens with time if left untreated. It is often mistaken for acne or eczema, or some other skin allergy.
Rosacea appears to be more common among fair-skinned people and affects an estimated 5% of Americans. Although the causes are not fully understood and there is no cure, there are a number of ways to relieve symptoms.
