Rosacea
long-term human skin disease characterized by ruddy reddening of the skin
Rosacea is a long-term skin condition that typically affects the face. It results in redness, pimples, swelling, and small and superficial dilated blood vessels. Often, the nose, cheeks, forehead, and chin are most involved. A red, enlarged nose may occur in severe disease, a condition known as rhinophyma.
The cause of rosacea is unknown. Risk factors include a family history of the condition. Factors that may potentially worsen the condition include heat, exercise, sunlight, cold, spicy food, alcohol, menopause, psychological stress, or use of steroid cream on the face. Diagnosis is based on symptoms.
Rosacea is not curable, but treatment usually improves symptoms. Treatment is typically with metronidazole, doxycycline, minocycline, or tetracycline.
