Rosacea is a long-term skin problem 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". Those affected are most often 30 to 50 years old and female. Caucasians are more frequently affected. Chronic contact dermatitis caused by cosmetics is sometimes misdiagnosed as rosacea.

Factors that may potentially worsen the condition include heat, exercise, sunlight, cold, spicy food, alcohol, menopause, psychological stress, or steroid cream on the face. Treatment is typically with metronidazole, doxycycline, minocycline, or tetracycline.

Diagnosis and Treatment
Make sure it is not chronic contact dermatitis caused by cosmetics. Long-term treatment is usually required. Minocycline is effective for acne-like inflammatory rosacea lesions. Brimonidine can reduce flushing by constricting blood vessels.
